Has anyone ever had any valve issues/concerns on '00-'02 426's? I'm thinking of going back to a big bore (sold my 250F) and I'm considering going to the "dark side" (Honda 450) but I'm not sure because of all the valve concerns I've read about in the Red Forum. I'm a little leary to go Red. I had an '01 YZ 426 that was rock solid reliable. In nearly two years I had it I never had valve issues, never needed adjustment, nothing. The bike started 1-3 kicks when cold and 1 kick when warm, guaranteed everytime. It was a great bike. I'm narrowing it down to YZ 426 vs. CRF450. Since I never had any valve problems with my trusty '01, does anybody else have any valve horror stories on their four-two-six?? Lets hear it.
