Modified for Open Desert 02 CR450F or early CR450X!

Recommended Posts

I have an 02 crf 450 that I have done the following modifications.

Lowered the compression to 10:1-Weisco Piston

Heavier Flywheel for lights-Baja Designs

FMF Q Pipe

Taller gears with an 18" wheel..etc.. etc..

I ride between 1600ft all the way up to 3000ft.

I have never adjusted the jetting from stock and the bike seams to run fine except on the top end. It seams like it is pinging a bit. I am going to be running a rather long ride from Lucerne Valley to Stateline (Nevada) and I don't want to get stranded. How can I tell if my jetting is on?:cry: Would a JD kit help? They seam more directed at a stock bike with no mods.

Thanks for any advice anyone can give! Anybody have a simular set-up?:cry:
