Ive recently added a FMF slip on exhaust to my quad. Will i need to re jet it?

 

anyone?

 

its a slip on-so no. u may want 2 slightly turn out ur air fuel mixture screw like a half turn but nothin else. if it were a system yes. but its a slip on so no. run it a lil, check ur plug and see what it looks like. if its back fireing when u "engine break" then turn out ur air fuel a half turn and chech again but u should be fine

 

It couldn't hurt. The jets wont cost more than 30 minutes and no more than an hour of your time if you really dilly dally.
