hey guys just got together a new pit bike it was running fairly terrible ( when i got stuck into it, it seemed to drop in and out of power and genrally running shit) so into the motie store she went for a tune. When i picked the bike up the guy said that he had tuned the bike to the best possible with the existing jet needle installed. he said that the one in the carbie is wrong because it doesnt suit the exhuast ( i think, i wasnt really listning) so i took it for another burn and same deal, bike did run marginly better but still fairly shithouse. There is a possibility that it is another problem but i would like to know
firstly: what jet i need
secondlu: where to get it from
and also if anyone can understand what my problem is it would be appreciated greatly.
(the carbie is a 30mm flatside on a yx150cc engine)
