Is it better to be on the low end or higher end of the specs. I replaced the friction plates after the clutch wearing down until you couldn't go until about half throttle. I installed the new friction plates with all the same steel spacers as I did with the initial install but the gap was far to wide. After replacing some steel spacers I got the gap to be about .035 and was wondering if it's good enough. This is for an 04 yz450. Some of the steel plates were blue. What does the blueing mean? I was using 20w50 rotella t oil.
