what do you need to do with the jets when you put an hmf slip on... do you need to buy a jet kit? when you buy the pips does it come with instructions? i know im stupid

 

Your signature says you have a yoshi pipe and the carb is jetted...what main jet is in it now? I put a 165 in mine,(came with the pipe), but havent checked the plug yet. It's not hard to do though, loosen the clamps on both sides of the carb, pull the boot off to the air-box, and twist the the carb clockwise (on the left side of the bike). You'll see 4 screws that hold the bowl on, take the bowl off and you'll see the main jet up in the carb.I did have to turn the air screw out about a quarter turn too.
