everybody in my area says not to rejet it when i put on exhaust and filter. they say it will run like crap. all the manufactureres say i have too. so tell me whats the deal because i dont know.

depending on what kind of exhaust you went with......will vary with your jetting demands. If you have a high flow exhaust you will def. have to re-jet b/c you will be lean. But that will depend on the altitude your at. After you put the pipe on see how it goes.....if its back firing when you let off thats usually a good sign of being lean. Buy a k-n jet kit follow instructions.....yur golden

u have to rejet, even if ur only putting on a k and n...if u put more air/fuel into motor, u must rejet or ur quad will run like a turd.
