Pretty new to the Rs 50 and just wanted to know what set ups you guys have and what kinda speeds and bhp if anyone has done a dyno? Cheers Glen:banana:(Dont know why i put set twice can't work out to edit it?)

This is gonna be funny ;)

Setup is below and top speed is 70mph on the clock with 15 52 (I think it's 52 not sure I do know it's stock though) gearing but it's still got plenty in it to go down a few teeth on the rear. Gps speed unknown but I would guess at about 65mph mabey :/

i would of thought you got more than that with that set up :( tbh ive not rode my rs as its getting the engine and stuff rebuilt atm im told it does 70mph. if you changed the gearing would you get more?

Glen1990
04-08-2012, 02:47 AM
but i did have a rx with am6 and just a cheapish 70cc everything stock but arrow exhaust and that did 60 to 65ish with stock carb not sure what rpm that was at since my rev cable snapped i was hoping to tune my rs to do around 70 ish ive heard of people getting more :S

what aftermarket parts has your bike got ? it would never hit 70mph stock ?

what aftermarket parts has your bike got ? it would never hit 70mph stock ?

For a 1999 to 2005 model? Normaly no, on Bonneville they got one to 75mph fully stock with just difrent sprockets, but realisticly you never get that out of a streat bike, 50mph they do stock with no restrictions in place, ad a faster pipe and a bigger front sprocket and you get up to 60mph.

Derbi engine has more friction so it looses some power just driving the engine round, and the long under seat exhaust isnt gonna help much also, so 70mph sounds reasonable, i hape it does accelerte really good though than.

Similar setup on a 1999 to 2005 model i exept to see 75mph~80mph, the trick is to balance your sprocket gearing so it accelerates good trough all gears with out screeming in 6th.

ive got a 2000 (am6) ive got a full arrow exhaust(well for my birthday) and 21mm Dellorto carb. sport clutch and 70cc what would you say is the best set up? i know this 70cc is one of the really nasty cheap 70cc heads that cause like 100. i was thinking of getting

http://www.adrenalin-pedstop.co.uk/p/Polini_80cc_cylinder_kit_for_Minarelli_Am6_engines-1774.aspx

do you think its any good? 19bhp seems a very high bhp clearly this is with a really well tuned set up im guessing.

what set up would you say? am i going the right way? you seem to know your stuff very well.

i may be wrong here but if i remember right then you should stay up to 19.5mm carbs with 70cc and then when you get 80cc - 90cc kits you move up to a 21mm carb from some of patricks previous replys - cud a slightly to BIG carb cause some lack in power?...............

yeah there's tones of power it's geared for acceleration at the moment that's why it only does about 73mph on the clock, i plan on gearing it for top speed when i have the money hopefully should get 80-90 maybe Patrick what do you think ?

again just going off what i remember patrick posting ages ago but i think patricks had up to 105mph with his Rs80 and the rest haha but the main thing is he geared it up like mad i think (obviosly wud dramatically effect acceleration) - bare in mind its gettin late so im tired so might be wrong but i think i remmber him putting something like that........

my bike still has the standard 50cc head piston etc, ive only put on a 19.5mm deloreto (or how ever its spelt) carb with an 85 main jet and a polini evolution exhaust, new 12tooth front sprocket and 47tooth rear sprocket and new D.I.D chain (ive still got my 14tooth in my room to go on ;)) and it will sit at 65 easy and will do just over 70mph on the clock.... so how mumbl3s have you only got 73 on the clock with that setup may i ask? :P

my bike will accelerate though the gears like nobody's business, i don't like to brag but if it only does 73mph top i think you can imagine how quick i can get thought the gears. but im more of a top speed guy i dont really like my current gearing but as im still breaking the engine in it doesn't bother me at the moment

i got the bike with the 21mm carb and plan on getting an 80cc kit my mate who i got it off said when working he got 72mph hes 6,7 and 15 stone keep in mind. and his friend whos 5,8 around 11 to 12 stone got 80mph im 5,11 and 13 stone just shows you what weights and stuff do.

but i do know alot of people with 21mm carbs on 70 set ups just harder to set up my k&n aint helping anything. plan on buying a used stock air box and fitting an 80cc kit i want to find somewhere to get my bike dyno tuned if i can

looks really good, but it is very cheap which makes me think a little

i wudnt advise buying cylinder kits off ebay ALTHOUGH i have just done it (stock 50cc cylinder kit) as im very short on money atm and saved a fair bit. and its running really well so far! :)

there are many ways you can look at it like you wud be saving like 200

Its a FAKE, Top Performance Pink kit, it should be 49.5mm wich is exactly 75cc (no where near 90cc)
I can tell in an instand the kit is fake, on the reall one the cilinder head says TOP, (but theres much more that tel me this is a fake) and on the orther side wich is not shown here it also says TOP, but not here, clearly a fake, and if i where you guys i would stay as far away as posible from it.

Please only buy Stock cilinders of Ebay, ive seen so many fakes on there from the big brands like Malossi, Polini, Top Performances, Metrakit, Hebo etc. only a expert can see that there fake, but sometimes even i find it really hard to spot (some do say the brand name on the cilinder, but that doesnt mean there reall)


@Glen: if that Top Performance kit was reall it would leave that Polini kit in its dust and be just as reliable at least but that Polini kit is still a nice set.

P.S. note there claiming 19hp for that polini kit, wich is not true, the single piston ring kit does that at +-14.000rpm, but this one is about 15/16hp at most with a really good set up, pink top performances gets 17hp~17.5hp.

Glen1990
04-10-2012, 12:06 PM
really? tbh i knew it was fake for that price. what would you say would be the best kit to get? ive heard you bring up this pink top quite a few times ive not seen it forsale in the uk tho :( i was hoping to get over the 15bhp mark tbh cause im 13stone and hoping to get around 70mph without any worries i know its alot to ask for a 50cc bike. i can't seem to find many 80 kits.

well the top end that was fitted(engine still getting rebuilt) was one of them very cheap 70cc heads same one as the one in the link i had one fitted on my rx they don't seem to give that great of a power boast.

i did take my old one to yamaha motorbike shop(nearest shop to me) and they said something about the porting being rubbish or something same as stock? :S i know it cant be stock bored out to that what im pretty confused about

chrism15
04-10-2012, 02:50 PM
if your willing to pay that for the polini kit then id just go for the same pink top performances kit that patrick"s got (a bit more pricy but think about it.... reliability good and the increase in power you want!) :) just make sure you upgrade carb, clutch springs and plates but most of all the crank! but youv already said you are after the doppler er1 which is a good choice.......

also iv heard them polini kits are not very reliable and are not a true 80cc but 75cc

dont mean to hijack the thread but can you get a flat top piston and flat top piston head for RS 50? ino you can get them for Rs125 and do they make a difference? if so then this might be a option for you glen............

Glen1990
04-11-2012, 12:17 AM
Think ill be going with this pink top engine, im rebuidling my engine now since my friend dont wanna anymore lol so this could be fun. and dont worry i made this for everyone not just my self :P any tips for engine rebuild guys? im getting the whole engine in parts ive got al bearings and gaskets new race clutch etc etc will be getting the crank too and ive never heard of the piston


from what i can see you get a flat top piston with pink top kit


if i got one from away do most places ship over to uk? ive noticed theres a hell of alot of fakes!!

RS_Patrick
04-11-2012, 05:43 AM
50mm kits are 76cc

Flat top head? what you mean? you mean a head with a shallow combustion chamber along the edge and than a little sphere shape in the center?

Flat top piston gives a bit more power, but its not a difrence you will notice.

www.easyparts.nl ships to the uk, i can make a whole list (wich i did in the past) but easyparts is more reliable/responds quick to email.

well if you have a flat top piston (litrally the top of the piston head - flat not crown) then you need a flat cylinder head for it to match - flat again not crown shape

44 products down is a flat top pisyton head for flat top piston on a Rs 125

You dont need such a head with a flat top piston, but you can, its just a way of raising the compresion.

what sort of difference wud it make? with a flat top piston straight onto a flat top head so MAX compression

Not so much that you would really notice it, only good is for racing where every tiny little bit of gain helps.

04-15-2012, 02:43 PM
patrick what exhaust do you have? im thinking of ordering ordering all my stuff from easy parts and get it posted to the uk the prices are shockly cheap compared to the uk! and im guessing you can't get the pink top from the uk can you link me to what you think is the best exhaust on easyparts

http://www.easyparts.nl/showarticles_info/010633632HF/0-4019-121-88-1790/303/Exhaust_Giannelli_Street_Rs_1999-06_Tuono_50_2003-06_%28without_muffler%29.html

is that any good? its beween that or the full arrow carbon system or this

http://www.myscooterparts.co.uk/motorcycle/exhausts-performance/scooter/motorcycle/leo-vince-v6-exhaust-with-titanium-muffler---e-marked/v6l4127/82/

the Leo vince v6 is almost half the price of the arrow carbon exhaust i dont know much about them tho the giannelli chamber with carbon end can is only little more than the leo vince v6 tho

RS_Patrick
04-15-2012, 09:24 PM
Mines no longer being made/for sale mate, got Giannelli Racing pipe, also got a Giannelli Street, theres no big difrences between them, have to put them next to each other to see it. (and theres no "E" marking on the Race pipe)

Glen1990
04-16-2012, 02:39 AM
if you had the choice of the 3 what one would you get? my bikes set up ready for the arrow. im gonna be gettin the pink top as well so im wanting one to work well with that


also Polini aluminium 80cc or pink top? both are the same price for me to buy but i can get the polini in the uk as well as spares,

i think the Giannelli pipe is the way to go with any aprilia personally (although i think leo vince are pretty good pipes TOO - i put one of them on my Sr50 and that made a big increase and nicer sound)

and polini top end or top performances pink, well from what iv seen patrick has spent time tuning Rs"s and thats what hes got so id go for the pink! :)

PLUS IV HEARD THAT POLINI KIT ISNT RELIABLE S0 GO FOR THE PINK ;)

Glen1990
04-16-2012, 07:00 AM
with the giannelli pipe im more worried about the pipe being a street pipe rather than the race pipe tbh

RS_Patrick
04-16-2012, 10:34 AM
Pink Top is extremly powerfull and reliable like i said before, Atleast as much as the 2 ring Polini kit wich is a bit more sensative/less reliable.

Giannelli Street is still good enough for a Pink Top and with the Kevlar silencer it sounds really nice also.

Glen1990
04-16-2012, 11:09 AM
so would you pick that exhaust over the arrow racing one with carbon endcan?

RS_Patrick
04-16-2012, 01:43 PM
Carbon is difrent than Kevlar, and the Giannelli Kevlar silencers really sound difrent to me compaired to Carbon or Aluminium versions, but its big silencer compaired to others also.

lol that been bought up that many times? i was just seeing if the exhaust was any good :P

their was a discussion on another thread coz i think ryan thought his Rs50 did 70mph with stock gearing and cylinder, polini exhaust and carb but anyway lets forget bout that haha

the exhaust ryan has is a good one but designed for 70cc/80cc but since thats what your getting then it will be suited

what can a 70cc - 80cc rs50 do 0mph to 60mph ?? roughly? just want to know if it will keep up with a hatchback like an audi a3 for examples sake ?

uugghhh thats a hard one in rekon

a Rs 125, mx 125, rx 125, sx 125 will pretty much PISS over most little cars up to 1.4 but a audi a3 wud hav more top end on stock

a Rs70/80 will keep witha small ish car but if u get like performance cdi and more then maybe faster

0-60 i dont know

i won a 1L corsa on my old aprilia rx 70. with stock carb not tuned right. only to 50mphish tho caused my top speed was only 55/60 cause of gearing but thats with take off gearing. oh im taking photos of most of the stuff i do this is my first bike ive put alot of money in to and work but i will add photos and stuff :D ive got my mind set on the engine. oh ordering Doppler ER1 tomorrow my mate got my rx off me with same 70cc kit as mine and the crank broke and totally messed up his engine like REALLY bad.

Audi A3 wouldnt have had a chance with mine, i got to 60mph in 4th gear, and than shifted to 5th. And my mates Golf GTI's are easly left behind wen accelerating away at the stoplights.

04-18-2012, 07:39 PM
a landrover freelander (old shape) was up my arse on my favorite road so i slowed down a bit to piss him off, and he tried over taking me so i dropped a gear and opened the throttle i think i was in fifth and he was still beside me at 12000rpm so i though fuck this im still breaking my engine in it's not worth it and let him pass
but if i kept at it would have i have left him do you think ?

also whats my setup like compared to your pink top bike ?

Glen1990
04-19-2012, 01:10 AM
with my set up ill be happy if i get 70mph when i get the full set up anyways. i know ill get more i just dont wanna set my target too high. shockly ive only had a honda cg that could do 70mph on flat out screaming and a chinese honda cbr copy so its gonna be faster than both my 125s they were only around 10bhp

Had yeah, and did 90mph top speed at something around 14.000rpm, made me wish i had an 7th gear sometimes outside of town.

We see if i rebuild her whats comming under there, got 2 engines and i rebuild them both at the same time, good fresh parts all go onto the engine with the least miles on it, and the other parts all go into the engine thats been under there for 12 years and that one will be stock maybe a little faster and that will be my regular running engine than.

have you heard of that really old suzuki? erm cant remember model but 50cc with 14gears!! me mate told me about it but chances of finding one now is RARE as they are collectors items and you"d be paying alot for one........... oh and i think it did like 100mph but it is a really old bike

so what havnt you done to yours then patrick?

and whats the plan now for you then since one of your bikes got impounded? coz surely its pointless having one stock and oninto the tuned to max because at some point you will take the tuned one out and get into the same mess again and be left with a stock one ect ect

Thats what your talking about mate.
1967 Suzuki had 2 cilinders 17,5hp, 17,500rpm and 14 gears, the 1968 had 3 cilinders, 19hp 20.000rpm and 14 gears, both did close to 110mph

They didnt impound my bike mate, they just took the registration papers and it had to go trough a kind of MOT to get my papers back.

I run the legal engine most of the time, i probably rarely run the other engine.

Was thinking the end pipe was a bit thicker but dont have it here to mesure it up.

Glen1990

its like 18mm and 16mm on the inside one the one i checked is arrow pretty much the same pipes are giannelli? the welding and everything looks the same

Top Performance Pink - 75cc
Hebo Titan Race
Dellorto 24mm
Malossi Powerfilter
Doppler Endurance Rod

Top speed is over 100 km/h, haven't got the chance to check the real top speed because i have 15-50 sprockets which sucks..

RS_Patrick
04-21-2012, 11:58 AM
Why such a big rear sprocket? stock is 47, and 15/47 is a nice gearing for that set up, gets you plenty of top speed and verry good acceleration.

Well, I changed my rims and unfortunately there was a 50 tooth sprocket on the rear wheel..
Will probably order new sprockets and a new chain soon! :)

What is the ideal sprocket combination for high top speed and nice acceleration?

Michelet
04-21-2012, 07:15 PM
Yeah, I saw it but I want to know if there is an even better combination..
A friend of me said that I should go for 14-47, so I'm a bit unsure.

I want to get better top speed (so 100km/h shouldn't be a problem) and an acceptable acceleration.

RS_Patrick
04-21-2012, 07:46 PM
15/47 mate with your setup.

Bike should do well over 120kmh.

The only problem you have is the Malossi pod filter, especaily you in Norway can really benefit from a Airbox.

Michelet
04-22-2012, 11:21 AM
Thanks Patrick!

I thought about the air box, but I'm afraid it won't give the engine enough air?
And it won't fit the 24mm carb?

Which jetting do you recommend with TP75, Hebo Titan, Dellorto PHBN 24 and stock air box?

stock airbox will give well more than enough air.......... and patrick replyed in another thread showing how to modify it so it has more air IF needed

with a open./cone/pod filter you need to jet up to near 100! and doesnt increase power that much so just keep a airbox on

RS_Patrick
04-22-2012, 01:05 PM
Openfilter causes problems in your climate mate, and you need a uge mainjet with it wich increases feul consumption.

I ran my bike fine with a completly stock airbox, it just didnt respont right on the throttle sometimes so i modded the airbox a little (do not just drill extra holes in it, this will make it worse) and added an extra intake tube in it after wich it ran perfect, responded perfect to the throttle and could pull away from 2,5~3k in 6th with out the engine spluttering or strugling to much. (goal was to be able to drive 50kmh/30mph in 6th with out the bike splutering or sounding really tuned up, wich worked also fine)

Glen1990
04-23-2012, 11:54 PM
im gonna have to get stock air box mine came with a k&n style with a 92 jet main.

Go-Kart style airbox will work also.

best filters are the ones made out of 2 layers of difrent material like Polini makes for the stock airbox.

i had one of them polini filters in my SR50 stock air box, changed it to a deeper and louder sound (not much just so you would notice) and it ran alot better like that with all the other mods

with a tp pink 75cc and my arrow racing exhaust and 21mm carb and stuff prob a tp cdi too and 14/47 gearing do you think ill be able to get around 75mph?

RS_Patrick
05-29-2012, 12:11 PM
yeah, piece of cake, you probably want to foit a 15 front sprocket though, might overrev in 6th with a 14.

Glen1990
05-29-2012, 03:43 PM
i live in a very hilly part in the uk (the lakes) so i need alot of hill power too its lost a fair bit of power on hills (my mate said since he went from 13 to 14) it lost around 10 to 15mph on hills. it was abit weird getting on my rs today after riding a gsxr 600

Glen1990
05-30-2012, 05:37 AM
i forgot to ask did you ever dyno your tp set up? or ever run one theres nothing said on the bhp on any of the websites ive seen

RS_Patrick
05-30-2012, 11:19 AM
No, i never dyno'ed it mate, only setup i dyno'ed on my own bike was a Black TP with 19mm carb and Giannelli pipe wich got to 12hp.

Michelet
05-30-2012, 12:17 PM
How many HP do you think an Aprilia RS50 with TP75, 24mm carb, power filter and Hebo titan has? :)

05-30-2012, 12:25 PM
im kinda hoping for 18bhpish... :( is the pink top more powerful?

Sweet cylinder :D

RS_Patrick
05-30-2012, 04:48 PM

Yeah, a lot more powerfull, between 15 and 17,5hp should be posible if you get your setup right.

Glen1990
05-30-2012, 05:12 PM
do you think its worth up grading from my 21mm to the flat side 24mm ?


also i have one racing peg rearset? and a stock pegset the racing one is TCM? i cant find much info online about them ever heard of them? ill love a matching pair

btw patrick im guessing the tp pink has fancy porting?

RS_Patrick
06-11-2012, 05:02 PM
Some nice transfer ports and a big exhaust port.

Glen1990
06-12-2012, 01:50 AM
i had a look at my bore and the porting is totally the same at the stock the sizes and everything :S oh yeah patrick i feel little silly now you know when i was doing the rear shock test i noticed something when i thought the rear shock was soft bouncing on the bike(me sitting on it) i didnt notice it was the front forks that were bouncing softly lol

oh thats what i wanted to know is it worth going from my 21mm carb to the 24mm(same one you have)? im gonna get a stock air box too im fine to do the mods

RS_Patrick
06-13-2012, 10:11 AM
I would fit a 24mm Mikuni Flatslide (TM24) yeah, biggest that works with the stock spliter and oilpump and it fitts with the stock airbox.

Michelet
06-13-2012, 11:55 AM
Patrick, are you sure that its the biggest one that fits with the splitter?

On my Dellorto 24mm I have the stock cable with the splitter on.
I just don't use the oil pump.. ;)

Glen1990
06-13-2012, 12:35 PM
the splitter isnt a problem i had to mod one to fit my 21mm tnt carb on my old rx cause it came with stock carb was easy to make it fit

RS_Patrick
06-13-2012, 05:07 PM
Patrick, are you sure that its the biggest one that fits with the splitter?

On my Dellorto 24mm I have the stock cable with the splitter on.

Its still a 24mm mate... and if you try to fit the stock airbox with the dellorto carb you notice that the airbox wont fit into place anymore as its 10mm to much to the back.

@Glenn:
You never mod the spliter, you just adjust/change/mod the cable from the splitter to the carb, all i did was make a custom throttle cable for the TM24, but AF1 also sells a ready made cable for the TM24 carb.

Michelet
06-13-2012, 05:39 PM
Im gonna use one of the air box intakes I have and try to make it fit ;)
Only time will show wether its going to work or not! :D

RS_Patrick
06-13-2012, 05:43 PM
Maybe if you cut a bit of the airbox rubber it will fit, but if i where you i start using the oilpump also aigain if you fit the airbox or its gonna run a bit rich with oil up to 2/3 throttle or so.

Michelet
06-13-2012, 05:47 PM
Yeah I know.. But I don't know how reliable the oil pump is.
When I turn the throttle the "oil pump" part moves as well. Will it work then?

RS_Patrick
06-13-2012, 05:51 PM
errmmm... you had it hooked up but there was no oil in there? thats not good :( pump gets seized up because its not getting lubricated, and causes extra friction, and posible damadge to the gears, so now its not reliable anymore no...

Glen1990
06-14-2012, 12:58 AM
ahhh right i get what you mean now so will i see much diff from my 21mm carb??

and heres all the info on the tp pink i found

http://www.rrd-preparation.com/en/Kit-70-with-80cc-cylinder-piston-cylinder-head-for-MINARELLI-AM6/93-product-93.html

noticed theres two diff head types ?

Michelet
06-14-2012, 02:47 PM
It's one inner head and one outer, just like on RS125 ;)
Improves the cooling! :)

Glen1990
06-14-2012, 02:50 PM
ahh ill get that one then i see how it works now really good how ever thought of doing it i will be dynoing it once i have my full set up my aim is 17bhp plus. i have heard of 20bhp with the tp due plus with a very nice set up not sure if its true or not

Michelet
06-14-2012, 03:19 PM
About the hp I don't know, but it's a really nice cylinder! :D
No problem to downshift and pass cars ;)

Glen1990
06-14-2012, 03:21 PM
yeah theres not much info on the hp if i get 70 to 80mph ill be one happy bunny

RS_Patrick
06-14-2012, 07:05 PM
It's one inner head and one outer, just like on RS125 ;)

The one with the inner and outer head is the later (3rd) version, should have slightly more power.

What i dont like though is that the first version had pistons coated with a Teflon layer to reduce friction, and they done away with that since the 2nd version, no idea why... posibly to expensive?

Glen1990
06-15-2012, 01:01 AM
hmm that is abit weird i know is the piston is flat i wish they sold tp stuff in the uk i dont know why they dont.


I have set up :top due + , dopper crakshaft , dellorto 28 mm , later i change exhaust with yasuni r3 ratio 15 -47 top speed is over 150 km/h and it has around 20 hp


thats what the guy told me about his set up hmm im thinking 150km/h is a little lie tho lol

RS_Patrick
06-17-2012, 12:27 PM
mine did 170kmh+ according to the cops that followed my with there camera car, but that wos with a smaller rear sprocket and it took a good while to get to speed in 5th and 6th.

Changed it later to 15/47 got 140kmh+ pretty fast. (100kmh/60mph in 4th gear)
Pulled way passed the redline in each gear, in 6th is got to 13,500~14,000rpm.
20HP is B.S. i think, never seen more than ~18HP out of it.


I wouldnt do a 28mm, but its your choice... if i where you i first would change the cilinder and maybe the pipe and see what you get than, 24mm Mikuni Flatslide setup like i had if its not enough for you.

Glen1990
06-21-2012, 02:58 AM
sorry didnt see this. yeah ill be happy with around 130kmh when i get it set up i wasnt gonna do he 28mm its this guys set up so my plan is tbh get the pink top kit and see how it is with my 21mm not sure about my arrow exhaust my mate has the same one as you the racing one not the street and the pipe is self is almost 100% the shame we checked the sizes and bends but thinking about the jolly moto then ill hope to be able to sit at 110kmh in 6th kinda thing but be able to get up hills still

Glen1990
06-22-2012, 04:41 PM
saw a new rs today my god they are ugly and small and you can tell they are a 50cc right away :( so glad i got the older model im looking forward to this set up with the tp pink would you get it ports smoothed? or is it not worth it

RS_Patrick
06-25-2012, 07:19 AM
Dont mess with the cilinder it self, think you could do if you got the engine split is match the transfer ports of the crankcase to the cilinder.

Glen1990
06-27-2012, 05:42 AM
found info that the pink top due plus 75 is 15cv any clues what bhp that is? :S the normal tp 75cc is 14cv

RS_Patrick
06-27-2012, 06:23 AM
CV means HP in french...

Glen1990
06-27-2012, 06:33 AM
ahh sorry i didnt learn french or anything cause i never went to school. so its only 15bhp? :S

RS_Patrick
06-27-2012, 06:52 AM
I dont know any french also, just that CV means HP, dont confuse it with the Citroen 2CV though, in that case it means 2 Cilinders. CV is short for Ceval wich means horse or horses

You can skip the reedcage if your buying the Polini Alu 50mm kit mate, your best of using the reeds suplied with it.

Personaly i would go for Top Performances 50mm Alu kit (9924130) instead of the Polini, costs a bit more though...

I was checking for both of these state side, an it seems us us guys just dont have any luck with those kits popping up here. I'll have to search uk stores that reliably ship to us.

http://www.rrd-preparation.com/en/Kit-70-with-80cc-cylinder-piston-cylinder-head-for-MINARELLI-AM6/93-product-93.html tp pink first data sheet ive seen for it still not got the bhp :(

http://www.rrd-preparation.com/en/Kit-70-with-80cc-cylinder-piston-cylinder-head-for-MINARELLI-AM6/41-product-41.html the polini alloy kit same porting at the cast by the looks for it tbh

http://www.rrd-preparation.com/en/Kit-70-with-80cc-cylinder-piston-cylinder-head-for-MINARELLI-AM6/1352-product-1352.html tp alloy kit?

i really dont know what one to go for. i was stuck on the tp pink but ive seen some lower bhp and speeds than what ill like and both polini kits are cheaper than the pink tp kit for me im so confused

how long does an alloy kit last? do you have to changes rings alot or is it just the whole bore goes? What kit would you get if you were me? For power i keep going back to the polini alloy as i feel at the 200 i can get it for with next day post its really good and i can get rings and pistons next next and spares but then i think the tp pink does sound good but i feel it lacks power like on the exhaust test the guy on there only got 15bhp on dyno with the due 2 tp 75 with it ported and race fuel :(

ryanperkins
07-25-2012, 04:47 PM
the polini kit is double ring so will last longer and be little more reliable and its like the porting on mine.. i think :P

Glen1990
07-25-2012, 05:08 PM
yeah the exhaust port is pretty nice and yeah looks to be

ryanperkins
07-25-2012, 05:29 PM
if i was you id get the polini as it'll be more reliable if set right :) and being cast iron it will last alot longer :D
i reckon it will be a killer on performance :D

Glen1990
07-25-2012, 05:36 PM
ahh i was thinking of getting the alloy polini tho

ryanperkins
07-25-2012, 05:55 PM
get the alloy then :P i have killed mine everywhere!! :L and not had any problems!! although ive had a problem with my little end bearing :( and gudgeon pin look in my project thread :L

done over 350km's in one day (more than once now!! :L ) i think its very reliable! :P

Glen1990
07-25-2012, 05:57 PM
im just thinking it will easy do 70mph and like i say mines more of a fun bike for tuning its not really an every day bike anyways =]

ryanperkins
07-25-2012, 06:54 PM
should have no problem doing 70mph! my 50cc will do 70 mph ;) really easy but then just over rev in 6th :L

chrism15
07-26-2012, 12:40 AM
go up a tooth on front sprocket to stop it over reving in 6th.. more top speed in it too! ;) @ryan

ryanperkins
07-26-2012, 12:36 PM
go up a tooth on front sprocket to stop it over reving in 6th.. more top speed in it too! ;) @ryan

i did but it takes abit longer to get 70, but will go off the clock on a nice road ;) but i prefer the acceleration as i dont go on really long roads :P

chrism15
07-26-2012, 01:10 PM
top performance 6th gear sounds like the perfect remedy! ;) even more top speed without losing accleration.. just rev it a lil higher before shooting into 6th :burnout:

You should just pull to the end of the powerband like usual in 5th gear... if you rev it past the powerband you wont accelerate much anymore and your just wating time in 5th gear.

The point to me with the TP 6th gear is that instead of changing the sprockets to get the bikes speed up and to keep it from screaming in 6th at top speed, as a bonus you dont loose acceleration in the first 5 gears.
