I have an 02 400ex thats pretty nice, it just leaks oil like crazy!
it cranks up perfect, runs perfect, and doesnt smoke except for a few seconds right after I crank it every now and then, not all of the time.
I ride it pretty hard and im interested in making it a little faster.
I do EVERYTHING myself and was wondering how hard this would be to complete?
Also Ive seen a bunch of diagrams online from when I rebuilt my kx125, anyone have one for a 400ex?
thanks for any advice/help
