do you have to rejet it if you get a slip-on

 

I would. They come lean from the factory. If you add a high flow air filter and a slip on the you must or risk burining it up. There's not much to it just dont tighten the jet down too much or you"ll strip it and then the headach starts.[img]i/expressions/face-icon-small-disgusted.gif[/img]

 

most of the time you dont need to. if you get a high flow filter and pipe though i would

 

At the very least, vent your airbox lid and jet up. Otherwise, it's a waste of $$$ imo.
