Power Problems on YZ 80

[YamahaMan09]

I recently bought a 1991 YZ 80. Its a great bike, and it has a new top end and everything. But sometimes when i hit the powerband in 1st and 2nd, it doesn't really kick in. I'm not sure why this is, because the other gears are fine, but 1st and 2nd don't hit in the powerband like they should. Could it be carburetor settings? Any help would be greatly appreciated. Thanks alot!

If it hitting in the higher gears i would think your carb is fine. It could be your clutch is slipping.. Heavy duty springs would be a cheap fix?? Otherwise you may be in need of a new clutch. If you do install heavier springs, you could also check the clutch plates for wear.. Good luck!

are u completely surei ts not kicking in? 1st n 2nd gear on a yz80 unless u are on pavement spinn the wheel easly. take it on ur drive way or some where u can get traction and try. next go where u have traction and hold the throttle open and slightly pull the clutch(its called faning the clutch) this will let the engine rev and let it go into powerban.

DONT do this in your driveway.

Hey, YamahaMan09, do you know of any good companies that make aftermarket parts for a '90 YZ80? I haven't been able too find too much and i thought maybe you would know something.
