klx jetting

Recommended Posts

just wondering about jetting/ piping my 2003 klx 400. i have never jetted a motorcycle before and I am a little nervous as to how and what kinda jet i should get :applause: . im looking at getting an full fmf exaust with a power core 4 header,mid pipe, and a titanium 4 muffler. and jetting charts or anything would be greatly appreciated. also would the power gain be worth all this money/ time?

thanks for allll your help
