i got a 98 900rr that coughs like a ****** when i clutch up a wheelie. it will get right to the balance point and then cough and almost die! if you keep on the throttle it will suddenly clear up and then jump up again and almost kill me!!!! it does'nt do it when you just accelerating though????? any body know what to go after first? i need it fixed fast for florida.

 

I used to have a honda 3 wheeler that would do that. took the carberator out, soaked it in gasoline over night and cleaned it out. put it back in, ran like a champ

 

they run like **** when they are low on gas.try it with a full tank.if you still have the problem then you probably have to clean and sinc the carbs.

 

full tank and cleaned carbs...... still ******' up! it's pretty cold out could that do it?

 

let me ask you this...what kind of air filter do you have?is it jetted?and inside the tank on the petcock there is a filter.there is a o-ring that sits in the middle of that filter dividing the the on and reserve settings.is it in place?also check the plugs.how do they look?sometimes because the bike is up in the air so much the cylinders load and foul the plugs.let me know if you still have a problem

 

thanks for the help! the plugs are new and the kid i got it from would'nt know a wheelie from a *** hole!. I'll go after that o ring though. got a k&n two bros pipe but i'm not sure who jetted it. you know jetting specs? i could pull them to see whats in there.

 

rub some tussin on it

 

i had the same type of problem with mine and it turned out that it was a number of things.one that o-ring turned on me and two they put a k&n without jetting it.the bike would fall on its face and then kick a second later.i put a stock filter in it and the problem was solved.the only other time i had a problem was when i would ride idle and it would feel like it was running out of gas with a full tank.that was the o-ring.put that back in it's place and the bike runs like a champ.just sinc the carbs every 2 months and you wont have a problem.or just listen to Roger and buy FI

 

tired that..... just made it smell weired

 

lol...

 

what's so great about an f4i for stunting anyway??????? I alwase rode v twins and think they are perfect! you barley even have to change the gearing!

 

yea they do stunt nice ,like sv 650's but they don't oil well and tend to blow up

 

good point! i blew the crank on my 03 sv. so i sold it after repair and my bro did the same! i'm going to weld a baffle in there to keep the oil up near the pick up.

 

check the piston return spring pressure...

 

way out of my relm!!!! i got a non heated garage and i drink beer until it is fixed! thanks though!

 

well if your #3 cylinder has a weak piston return spring its going to cause spikes in the power... these springs have a rare failure rate but i highly suggest having them tested, it only runs about 200-300$ and they cost about $100 to replace. if one does completely fail your going to ruin your top end, the piston rod will throw the piston into your valves etc and it will cost you 10x more...

 

i'm a certified bike mechanic and i have no clue on what spring your talking about.the 900rr doesn't have rockerarms so there is no springs in the head outside of valve springs.maybe your thinking about something but calling it something else.explain what your talking about.nice job on the kawi by the way.polishings a bitch,check my myspace for my custom zx9

 

cool, i'll check it out! can i do it my self? i have a good relationship with my dealer and they let me borrow ****.

 

yeah im just totally bullshitting him so he goes to the dealer and ask's them to check his piston return spring pressure

sorry man but ur bikes carb'd, thats the problem haha.. n/m the piston return springs !

 

oh any yeah about the polishing thing, prepping it for polish is easy... making it shine sucks! ima stick to chrome powder coating or anodizing etc.. never again polishing a damn thing !
