Wow that is a nice project! :D Really original.

Nice Fabrizi pipe with Yasuni silencer. Nice LED light and tasty Smirnoff Ice :rollin:

that's genuine Fabrizi silencer it just looks like Yasuni silencer.


you sure are a big person you made the scooter look like a minibike now i know why 10" tired scooters never became popular in Europe.:lol: :rollin:

also when i'm finished setting up my Jog scooter i'll post the pics here for everyone to see.

Nice work, post some pics when youre done!

Query: from that link, are those rims anodized or painted red?

01-27-2003, 11:58 PM
tiba look at the drop bar i told you about ! you need one !it worth 10kh on the top plus really transform the handling --i just made one from bicycle tubing and upper clamps

sure 12 has more grip but isnt NRG come with 10 and wining all races in europe ?

NRG has 13" wheels you may be referring to the Piaggio Zip SP LC which has a 10" wheel.

oh so that was the drop bar you're telling me about, i can get one from Kymco Sniper scooter from the breakers here in Manila & they cost only a few hundred pesos.

01-28-2003, 11:31 AM
the one in picutre is adjustable and extends forward quite a bit --plus sloped down and back a little so you can lean forward and down to catch less wind -- when cornering your body sit lower so lowering center of gravity

if you sit back and hit front brake your front wash out (assuming you have decent disk up front)-- but if you put your weight on front forks its will grip and stop --

The silincer on the Fabrizi pipe IS from a C20 if you take a look on the following picture you will see a:
Fabrizi with C20 silencer. Metrakit Pro Race with Fabrizi silincer. The rest of the C20 and a Ixil twin:

Thanks for the pics! It is great to see other's scoots, especially from other countries. The red-on-black scheme is sharp, go with it!

01-28-2003, 04:45 PM
It is Acctually funny that it looks like the LEDs are on. There is 5 LEDs in the NRG "wing" but there are NO power on it...
Strange thing..

Told ya it was a C20 silencer :lol:

And his Scarabeo now has Yamaha Aerox / MBK Nitro wheels, which are 13".

Stock Scarabeo is 10".

NRG has 13" also, while the older TPH (Typhoon) models had 10" wheels, but the TOTAL wheel+tyre size is almost the same (130/60-13 vs 120 or 130/90-10) Now zip has 100/90-10 which are indeed the small wheels+tyres.

NGEK!:lol: you got me there Dutch.

Velo you have a nice collection of exhaust pipes on the rack do you think you could give me C20 pipe if you're not using it anymore? Joke!!!:lol: :rollin:

IP i'll try that drop bar you suggested on my 50cc Dio i road race and of course i have DECENT brakes up front it's KRS 220mm big disk mounted on 10" alloy wheels, i also have EBC pads, steel braided hose (KRS).

01-29-2003, 04:26 AM
Valo how you compare pro race pipe with yasuni ? metrakit look even shorter than yasuni so must rev for ever or is it ?..

i assume fabrizi used for street riding while the other two for track

01-29-2003, 04:35 AM
bigger heavier tire and wheel combo take more force to spin and stop --so 10s accerlerate faster but are handfull in rain also a bit scary when you hit a road bump at 100kmh with those 10s-

Yasuni C20 pipe (no silencer) much shorter tha Metrakit Pro-Race pipe, they say Pro-Race is a very peaky pipe and has very narrow powerband so it's a nightmare to set them up correctly.

i also want Mr. MBX to make a race pipe custom made for both our scooters but do you think 120mm belly section is too much for a 70cc scooter? we'd better as Mr. MBX about that. i'll send him an E-Mail.

01-29-2003, 11:30 AM
he is using Mota so must input paramaters -- like bore stroke -etc .. -- chinoy pipes come very fat with imposible ground clearance with record breaking power

tiba i need your help --i need to calculate top speed with my RPM counter--so i can choose right gearing for given track -

i need to know max overdrive ratio with big pullies --you can measure max underdrive --its same thing -- i think its 2.8/1 for stock pullies -- does mallosi pecify exact overdrive ratio ? is my set up same ratio as mallosi overdrive?

how many turn rear pully does for one front revolution--or viseversa --whichever easier--

also tell me bridgestones tires cricumfrance if you know--
here is the formula :

RPM x wheel circumfrance in meter X 60
max overdrive ratio X primary ratio X secondry ratio X 1000

Sorry. But you are WAY off. The Stock Scarabeo is 16"
I have this pair for a "Street" Bike:

Tiba Karotsu:
Do you have any pictures of your racer?
The Pro Race IS WERY difficult to setup. That Is why I made my own pipe out of an old Nardo.

I could manedge to drive the C20 with the Pro Race cylinder and actually not the Pro Pipe ither. But on a 40.2 mm Polini Evo cylinder the Pro Race starts to pull at around 13500/14000 where the C20 begins to roar at 14000+ rews on the 50 ccm. Allso when you are close to them. The Pro Race seems wery long and it is easy to see on the cones that it isn't easy. Is is just a long piece of pipe with a wide middle.

The Fabrizi Scarabeo will be used on steets and Highways for fast cornering and HIGH speeds I was promised 100 MP/H at Fabrizi in Rome. So I'll see if it is possible.
It is allso going to be used in illigal Danish street racing scooter movies sometime...

My BIG typo. I knew the Scarabeo had indeed 16" wheels, I really mad a big typo there.

Yeah Pro Race is too hard to setup good. Some people here have tried it, but its peak power is near 16.000 rpm's. And the wear of piston and ring is insane.

Ow and 100 km/h?? That is way too slow for that setup.

With a Cast-Iron Polini Corsa (Ghisa) 21mm and Ginalli Nardo I went 100 km/h.

Evo/MHR/Manston go anywhere from 115 - 140 km/h

i don't know the circumference of the BT39SS 90/90-10 tires installed so you'd better use tape measure 'coz yours is already mounted on the alloy wheels i sent you.

so far on big tracks like BRC & 1/4 mile drag racing we use 17 x 31 secondary gear kit, shorter go kart tracks like CRC we use 16 x 31 to 15 x 31.

final gear ratio for those gears is as follows using stock 13 x 48 primary gear.
17 x 31 = 6.73 FGR (final gear ratio)
16 x 31 = 7.15 FGR
15 x 31 = 7.63 FGR

i also don't know about Malossi MHR over & under drive but the variator i sent you has more underdrive than MHR 'coz of smaller 18mm OD hub pin (Malossi only has 20mm OD hub pin). i think overdrive is the same that of MHR variator 'coz maximum belt travel is limited by the rear pulley assy. 'coz it won't split apart anymore than it's designed so only 95mm of pulley is used from the 99.5mm Malossi MHR variator i use. your variator has a slight advantage compared to my MHR variator 'coz yours have more underdrive.


once it is finished i'll post the pictures here the engines is still apart waiting to port the transfer tunnels to match MHR Speed cilinder. it's only a TDM (Taiwan domestic market) Jog 50 AC scooter which is fully stripped down for maximum weight reduction then the frame is painted over.

i believe Dutch, Ace & Micah still has a movie from one of our drag races and it shows my scooter in action, you can ask to send them to you the MPEG so you can see my scooter.

01-29-2003, 11:11 PM

he said 100 Mph = 160KMh -- i think w/big wheels can reach that speed because of taller ratio--
also he said C20 is more peaky than pro race pipe --

if it comes on 13500 on a 50 it should start puling around 12500 with 70 which is not too high


how that EVO pipe works if put on 50cc with race porting ? i unstrestand it designed for a 70 not 50 --

tiba karotsu

evryone seems to have typo errors nowadays? i wonder why?:lol:


yes EVO 70cc pipe will work as well on 50cc cilinders, i have used it on my other Jog Super Z scooter (JDM) with mods listed below;

Stock 50cc ported to 180 deg exhaust (up from 16:cool:
transfers are stock just cleaned them up
.35mm Polini CF reeds for stock reedcage
21mm carb Dell'Orto
stock crankshaft
"hot wired" stock CDI (6 wire)
lightened stock magneto 480g (down from 750g)
"tuned" stock variator with 18mm hub pin
stock belt
Malossi rear torque drive half pulley (115mm OD)
Malossi yellow big spring
Keli 2G race clutch
14 x 34 secondary gear up kit

this combo ran a best of 115kmh and this has mild port duration and no race crank. it will run faster if it had more radical porting & high volume race crank like SEF, MHR or Polini. TP cranks have 40mm stroker but looks exactly like stock crank except for the race con rod it has.

do not run inner rotor ignition on 50cc set-ups lightened stock flywheel & total loss ignition is the proven set-up for drag & road racing just get very good racing CDI.

EVO 70cc & 50cc has the same chamber & stinger only different header pipe diameter (EVO 70 is 30mm & 50cc is 25mm) so insert a sleeve to reduce the ID of 70cc pipe to 25mm and port the mouth of stock 50cc cilinder exhaust port to 24mm.

fastest 50cc drag scooters here run a 40mm stroker crank (TP & SEF) and 41.5mm piston dia plus exhaust port height is 21mm measured from BDC to top of exhaust port so duration is well over 190 degrees. they reach speeds of 125+kmh and have ET's of 16 seconds in the 1/4mile.

Hmm my second mistake. I really need some glasses I guess, he indeed said miles, not km/h 8o

01-31-2003, 08:47 AM
Tiba check your email -- i tried to send by online bank but they need bank swift and routuing -

i was thinking to use a vacum operated pumps as water pump --it works by intake vacum so no electricity needed nore it has drag like mechanical ones plus it cant fail -it used by Kart racers as a fuel pump-it weights only 50gram and made by Mikuni and is very cheap but i have to improt it from us or australia --so please look for one -- i left only one coil in stator --all lightening coils hacked off --

i couldnt find a machine shop in this little city --so i cut the flywheel using a small angle grinder -i didnt want to ruin the original magneto so given a spare by shop --after 6 hours of hard work i find the spline to be wrong size ! now i must repeat the job again on original magnito -i got it down to 490gr but got blisters all over hand and went over 6 grinding wheels --

i dont know when parts arrive because of holiday here despite spending another $100 on express

115km is nice example for low cost mods and stone reliable too-- now you should raise the cylinder at least 1mm and cut the top by same amount to atain more overev and top speed , now i wish i had access to machine shop here--
