A little (off topic) PW-80

I just bought my 7-year a new PW-80 (had to get him a Yamaha, start him young in the Blue family :) ). I'm trying to find a web site that is similar to TT, that I can ask some performance question about carb jetting, specifically to this bike..... Or maybe someone here might know. Should I follow the general rule of changing the main jet (125#) by 8 - 10% to compensate for the altitude of Colorado and drop the main needle by a clip or two?

Thanks for any help,


Have you removed the restrictor in the exhaust pipe ?, If you haven't it make a HUGE difference :)

Other than that mine is stock, but fair rips for an 80 :D

Yep, that was the first thing that was removed...
