the bike just had a top end rebuilt, and was in the shop for almost 2 weeks, when i was breaking it in, it kept stopping when idling- i drained the carby and found alot of sh*t in there,ithen it went fine, but then stated doing it again. when i got home i drained the carby again to find more sh*t in there and i cleaned the jets to find i had a partially blocked pilot jet. when i went to take it for a ride the other day- it kept bogging when id crack the throttle but when i would rev it slowly it would be fine. i tried adjusting the fuel mixture screw but it did nothin and when it would be screwed right in it still idled. im thinking accelartor pump promlem but im not sure??
