bike has good power, new clutch, cleaned powervalve, but during my yearly check i found a small piece of carbon fiber reed missing on the corner of one of the reeds(pretty small), but idk it might contribute to the problem. the bike has normal low end power like ever other 125 but when i get on it the bike will rev high almost like the tire is spinning but i went on the road and its not spinning. so idk maybe it could be to lean on the top end. and also in between shifts when im on the pipe it will make a quick hesitant pop so idk what ya guys think? reeds? jetting? tranny?
