ok i bought a 97 yamaha rt100 dirtbike to mess around with till my blaster is going again. thing ran great for the last few weeks. the day i got it, even tho it ran fine i took apart the carb and cleaned it all up just to be sure and it went great for a few weeks now out of no where it boggs at full throttle. like its having trouble reaching the higher RPMs. no mods at all on the bike. all stock. i took the airbox lid off, and it seems to ride fine.. i just cant remember what that means. lol i remember reading it on the forum i just cant find it. any help guys?
