03 ktm 525 sx question for james


Just got your kit in the mail the instructions are really straite forward and all but I am going to install an exhaust at the same time I do your kit and I was just woundering what changes if any should I make to the jetting.

The 525SX setting is for a more free flowing exhaust like most aftermarket pipes. If it is a straight thru design, use the same setting. If it is quieter, try 1 clip position leaner (#3 instead of #4) and lower the main jet 1 step.
