can anyone help me please?? every time i wheelie on my fiddy for more than 2-3 seconds, it just dies and wont start for a minute or so. if i just ride around both wheels on the ground, it rides normal

 

used to allways have an answer to everything in 2 minutes on this forum..........now its ****.....most the people who made sl great is now mad at shugga or not registered anymore.....sl is going down FAST

 

is it all stock or is it modded?
you mean regular wheelies or 12's?

need more info, and then i'll try and help you.

 

its stock with airfilter and 65 jet, only got like 2 hours on it

and about wheelies its just normal wheelies

 

wow, 65 mainjet? kinda big dontcha think? i run a full tbr pipe and k&n on mine, and i only have a 60 main.
that could be your problem right there, it's probably running very rich. i'd try leaning out the carb. i'd be willing to bet that'd fix it. if you don't have a bunch of jets laying around, try putting the stock one back in and see what it does then.
one of the guys i ride with has an all stock motor, stock pipe, and a k&n filter, with the stock mainjet, i opened up the mixture screw a lil bit, and it runs fine.
a 65 i.m.o. is way too big for a stock motor with the stock exhaust.

 

THANK YOU !! i bored out the stock jet straight to a 65 when i got it so ill have to buy a new one soon as possible.

is it possible to make the stock airbox run as good a airflow as a kn type filter? also do you recomend modding the exhaust, i mean will i notice the difference?

 

Well, i have a tbr full exhaust, k&n, rev box, and a 60 mainjet, and top speed wise, it's not that much faster, deffinately has more grunt at lower revs though.

you bored the jet? how the hell did you do that? ANY movement by the jet or the drill would throw it way off. why not just buy a $2 main jet?

 

My 03 came with exhaust (bought used), I put the stock one back on and it wheelies better now. Leave everything stock, put a stock jet back in there and just ride it.

 

yes i bored it out with oxygen i think its called in english cos the dealer did not have any jets this small.

do you think the pipe makes the extra "grunt" cos thats what i wanna have low end power, and not too loud

 

are you running stock airbox?

 

depending on your speed i dont know if your riding wide open
usually the symptoms you are talking about are cause by the float level being off main jet is working from 3/4 throttle to wide open no where else
when you drilled out the jet you may have messed up the float level id would check that also

 

true, main jet is "technically" for 3/4 throttle and above, but an oversized mainjet will cause problems elsewhere in the rpm range also. you have to keep in consideration that the stock carb isn't a cv carb like on most fullsized carb'ed bikes, so main jet sizing is going to have more of an effect on overall performance, not just at bigger throttle openings. the needle/slide is opened directly with the throttle cable, not with vaccuum like on a cv carb.

but like z50 said, i'd check the float hieght while you've got the carb open, it's easy to bend the tab on the float if you're not carefull.

 

maybe im gonna look into that soon a possible. floatlevel was off the day i got it brand new.

 

im gonna try a 60 jet and check floatlevel, and maybe go back to stock airbox what do you think?

 

i have a 60 in mine, but thats with a k&n and a tbr pipe. still may be on the big side, but it'd be better than a 65.
