[QUOTE="sick 96 250, post: 1336708, member: 54932"] For easier starting I would focus more on the reeds, take them out completely and look and see if they are sitting flat on the cages with no gaps. It could also just be a pilot jet issue for starting as well. Have you tried to turn the air screw in and see if it helps? If its not getting past half throttle it does sound like a main jet issue, could also be the powervalve is adjusted wrong or not even connected properly, esp if he put the whole motor back together and had the same issue then. I would check that real good and clean the carb yourself, not just pull a jet and say its clean, completely remove the carb, disassemble and clean the crap out of every hole in there. How is your clutch adjusted as well? I never had it happen to me but I have seen people over adjust there clutch way to much and when it would try to get into the higher RPM's just slip like crazy.
