I was giving some thought to the often maligned valve issues on the VF500F and thought I would post an RFI here. I have read in previous posts that the number one cause of dropped valves on the VF500F is valve spring float due to the limits of manufacturing back in the day (as noted, this can be corrected with modern springs and retainers from KPMI or R/D Springs). My tech question is whether an incorrect valve lash setting can also contribute to premature wear and subsequently a dropped valve as well. For example: too small (lash < .13mm) and the oil does not have enough room to properly lubricate between cam and the follower leading to premature wear of the surfaces of each too large (lash > .13mm) and the rocker arm tappet screw creates a hammering effect on the top of the valve stem which can lead to the spring retainer coming loose - never a good thing Any insight would be most appreciated. Thx!
