I have read different threads about removing the exhaust cones and improving airflow as well as neutering the throttle restriction which are all relatively simple to do. But what else is involved?
I have read different threads about removing the exhaust cones and improving airflow as well as neutering the throttle restriction which are all relatively simple to do. But what else is involved?
excuse the typos it is late and i am tired ..i too just purchased a svx 550 had it a week today ...was trying to purchase a left over o8 from ridershill in daloniga?? i was suppose to be up there riding this past weekend ..riding up there is why i bought the bike my r1 is giving the new baby dirty looks ..it was suposed to be raining... so i opted to stay in fla ... the price was good but they didnt have any reasonable financing avalible... so i bought mine in palmbeach fl ...stock it was omg slow i think a vespa scooter passed me it had a whoping top speed of 63 ...
there is a throttle stop...it only alows the throttle body to open about a light 1/8 inch... you need to remove the tank ...and the top and middle sections of the airbox.. i needed to make a special tool ....a reg 6 inch # 2 screwdriver with the handle cut off to the size of a stubby handle ....to get to the front screw on the right side of the airbox...needed the reach but there wasnt enough room for the handle ...the stop is located on the front of the front throttle body likage ... it is about 1/2 inch around silver on the inside of the linkage you can get to it from the left side w a long screwdriver .. it has a plastic cap over a straight slot screw ...i just smacked the cap w a screwdriver and broke the cap out it is dificult to see let alone get to make sure the pieces dont get into the motor ...then unscrew remove it and that is done...
there is also a restrictor in the top of the airbox it is in the front of the top.... it is just behind what reminded me of horns.... it is s pop out it is about 1/8th away letting very little air in ...push it with your thumbs remove it and reassemble the box ...twin air filter is preferred but noone seems to be able to get me one ...they arnt listed in the catalogs for a xv ...part # anyone ...xv asylum has a good article on synching the bodies ect ..if you feel inclined ill trust the italian to start if it isnt right then i look there .. the whole site hase alot of good tips
the corks in the exhaust you need to remove the headder pipes from the motor just as the pipes enter the mufler there are 2 cones ..i dont think i could get my pinky in them .. you will need to take a die grinder and cut the tacks ...a dremil tool will aslo work ...it you feel enthusiastic you can clean up the welds on the inside of the head pipes just inside the flanges as the gases come out of the motor... it is weld it is real hard will just chew up and spit a cheap bit back at you ... so get a good one...
the spark arestor... well they dont really inhibit the gases enough to worry about and you have fire roads to ride up there so you need them in to ride them the park ranger love to bust you so i would leave them ..
you also have a smog pump or air recirculating stuff the little 1/4 inch tubes boming off the head pipes ...i cut mine off and welded them up with stainless but that is not practical for everyone just go to the local automotive store and get rubber vaccum caps and cap them ..the tubes are long enough the heat doesnt travel up ... far enough they wont melt.... it was a rubber hose you took off ..remove the pump from under the black cover on the right side as well the charcole canister from the left there is a small hose that went into the airbox i just pluged it ...
that is what you can do ...now you need to get the new map in....e axone?? is one system... my dealer now used a navagator system ...or you can get a tune boy but for 500 !!! well ill pay the dealer for a half hour to flash the comp ...if i were racing well different ..
very important they must recalibrate the throttle position sensor to see the 100% you now have or it will not run properly ...
i think 15007 or 150017 the 15s are for the svx 550 is the current program for the sxv my tech said something else i was being usherd out of the bay..and didnt hear what he said aprilia told him to use i think he loaded the rxv map i need to check ..xv asylum had a list ...i was the second aprilia they ever sold... they didnt know anything about them yet ...they were great but about it all but 4 trips over an hour away i was teaching them ..the look on the techs face after the test ride said it all ...totaly different bike
tips i didnt like the orange side panels ...i skuffed them and painted them with the plastic paint from rustolium ..then cut black vinle and covered the flat that is exposed and most likey to get scratched ..the vinel was leftover from my dirt bike number plates ....i need the part # for balck side panels my dealer is new and welll.....
want a black fender as well ,,,note.... the difference between the street version and the supermoto is ....the super moto is only the front half ..the rear section catches the air and contributes to head shake ... i hit 115 and it was trying.... weight back and get a good grip suspesion adjustmet nessisary think stiffer rear ..she is still stock and i weigh 160
i also need a part # for a black supermoto fender it is like 45 bucks... for the short i cut the back off mine mine and cut about 2 inches off the front matched the shape to stock sanded the edges w 600 and look fine just isnt black ...
us 12 liter tank they didnt remake the sub frame they used spacers ...i JB welded mine to the sub frame so i dont need to chase them around the shop
26 psi seems to be a good starting air pressure for a supermoto bike ...
i reeled the blinkers in in the rear they look similar to stock but are smaller they are led ...they just seem to stay on and not blink ineed to wire in a resistor somehow need a little help size ohm how to wire ect ..they look good
the front... i have the zeta hand guards w blinkers mounted in on my wr vancoversupermoto.com..they have the same angular look as the aprilia... i think in am going to steal them from my wr ..whatever ones you buy make sure they have metal in them or you will be replacing them ...they say the blinker need to be 10 inches apert here that works ....
the stock tail is lanky at the least i just nipped mine sanded it smooth and bolted the tag part up next to the tail light ...then drilled small holes in the plastic where the blinkers attach and stuck white leds i bought at the auto parts store in the holes from the inside for flush tag light real bright over the sides not so in the middle ....kinda hard to read at night.... but it is well lit i am ..well ok with that ...
sliders small hard skateboard wheels 3 ft of stainless all thread and some washers if you take your dremel and open the inside of one up it will cap the rear axle ..and i even got them in italian colors and have less than 45 in both axles ..i have sms on my wr these look just as good and probabley work better will keep that swing arm off the pavement
if i have said anything wrong someone please correct me ...i have only had my sxv a week this is just what i have learned ..i havent seen all this info in one place here could be good for all the newbees it is a really cool bike in looks and performance ...and when the cop pulls you over play dumb and sell it is a dirt bike ...i couldnt have been going that fast ...it worked he didnt give me the ticket ....

Thanks for all the great info! I used to live in Boynton Beach off Gateway Blvd, but escaped the asylum 4 years ago. Been doin a ton of offroad riding on my KTM 06 300XCW. And a little street stuff on my '01 KTM 520 motard. Had a '01 R1 with 150 to the rear wheel which I sold before I moved so I was missing the power - but not the weight..aaaargh!
Anyway, always loved the look and twin config of the SXV so figured it was time to update my motard.
Once I get my '08 SXV 5.5 (this week) plan on making some molds and doing some CF parts - front fender, tank, and chin brow - still have the old one off my 84 FJ1100 to cut and fab up for the tool. Should give the bike a unique GT look.
You were right about the weather, wet all weekend! I had planned to go to the trials event at Trackrock Campground but opted to work instead.
Im a Palm Beach county guy too. I was at the dealer today talking about a 550 they did work on and said it was a rocket. Im sure they are talking about your bike. I just left a $3000 deposit on a new 08.
I also lived in Boynton and Gateway, how wierd.

if it was broward it probably was ...i just got it back friday ..they are new with aprilia so getting there computer set up was a challenge ...rudy stayed with me and we got through it ..so he is good now ...i did all the removal of stuff ..they just set the comp but the look on his face when he got back was well priceless...he took off in first ..the front came up ...second the front came up... the rise in the parking.lot??? ..both wheels off the ground about 8 inches... slide sidways to get it slowed ..running out of parking lot ...came back telling the other tech that in 3 rd he hit it and she stood up and that it was a monster ...they all thought it was a cool looking bike but didnt really get the supermoto thing ..they do now ....and mie is still stock i still need a pipe and airfilter ...i weighed mine today full of fuel 304..did you see marcio ..i am suppose to go to a supermoto track in miami this upcoming weekend i am using my wr though ...my boots need to get here ...30 buck and go have fun im in
What converted me was a few years back '03 I was in Tennessee at a friends house and we had come back from riding our motards and decided to take our sport bikes out - R1 and Honda 600. We both came back and said the same thing simultaneously - "I'm selling my sportbike".
If you go west off of I-95 on Gateway about a mile, the first apartment complex on the left is where we used to live. You turn left and drive between the lakes. Quantum Lakes that was the name of the complex.
