Engine loses power after warmup??

ಠ_ಠ Jon Folks ಠ_ಠ /

Hello, Ive got a Yamaha RD125, which isnt really a moped, but I was wondering if any of you guys had any insight into this. Basically, when I first run and drive the bike, its fine, but after its warmup up for awhile, it beginning to go slower and weaker.

Does anyone have an idea of the cause of this?

Thanks,

Jon

Well...........it could be the piston is starting to seize due to lack of lubrication or too little jetting. don-ohio
