Hmmm, the sharp of eye might say, "hold on there... some of those exhaust valves seem to be thin of margin"......




and you'd be correct....... 4 exhaust valve were marginal on the margin



although .8mm will likely still have "enough" margin after being cut, once you add in a stronger spring, and likely hotter temps, I want exhaust valves with a bit more than the minimum, so I dug up some exhaust valves to replace those I've removed.


More to come.......
