Ok, the dealer just got my W/B slip on pipe today, of course, I put it on, took it for a ride..... but now at high rpm's it falls on it's ass and sputters... Do you think I need to bump up the main jet a couple sizes??? I thought it was supposed to work with stock jetting. I also took off the end of the pipe then put it back on, is it possible I tightened it too tight (highly doubtful but something to think about).... what's the stock jet size, maybe i'll try to go up a couple sizes..

if it didnt do that before you put the pipe on, then most likely it is because it is too lean. so go up a couple of sizes on the main jet and probably move the needle clip down a notch.

I am pretty sure its your float bowl. Mine does the same thing. Tell me this, do you notice it alot more when you hit the whoops too?? Or when in airtime jumping>? Try it on the whoops and tell me if it does it alot..If so, then its your float bowl I would say.. when its slappin around in ther its else getting too much or not enough, most likely not enough .In my case, with a direct K&N to the Carb, its breathin bigtime and injesting more fuel if your flaot bowl is off, this will cut out and sputter and cause power loss and sound alot like a bad plug or cutting out sound..... Also do a good plug reading.. Whats your elevation? and what main are you running right now?? TINA :) BTW. Are you running stock filter too???Or a K&N??

I'm running the stock filter as of right now, can't decide whether to get the Clamp on K&N or the Airforce...... Ii haven't touched the carb, i'm still running the stock main jet... 150?

If it is the float bowl then how do I fix the problem??? How do you adjust the float?

Thanks, Sean

Mine sputterd and popped realy bad from mid to full throttle, the float was adjusted and the spacers removed from the needle and now it runs great. It revs much quicker to the limiter, almost like a 2-stroke.
