I am new to the forum here, but i have always read the discussions from time to time and decided to change my WR426F over to the YZF cam timing. The jetting that I had prior to the change seemed to be OK. I was just wondering if I would need to re-jet and maybe what others have jetted their bikes to. I live in Colorado in Ft. Collins and haven't gotten to ride it since our huge snow storm to see how it seems to be jetted. Thanks again!
