I just purchased a full yoshi comp system, I am currently running with a K&N airbox lid off and a hrc end cap...not hrc kit though. My questions is will I have to change the needle and pilot jet with the new system. and if so do I have to take the carb off the bike to change the needle and pilot. Also when you talk about needle clip position which is richer and which is leaner. sorry about the newbie questions. going to try and jet the bike myself, any instructions would be appreciated.
