Anybody else here with the older RFVC doing the valve spec upgrade?
Hey GM. For what it's worth, my machinest guy who knows these (RFVC) engines very well has always said the stock Honda clearance was too tight. I think mainly because of oiling issues but also .002 doesn't allow much for thermal expansion. And we all know these bikes have their fair share of both.
