Ed, I found that measuring the head clearance using the solder wire method indentation is quite high using stock 0.3 mm shim on a NovaMax and a RR12L5 casing. I found that without any shims under the button head, the head clearance is already 0.5 mm which is more than enough I think... I might be wrong. Using 25% nitro with 7tf turbo plug. Is this normal?
Since the head clearance can differ from one crankcase case to another and therefore shim info cannot be used, what should be the correct head clearance for the .12 BRB piston sleeve?
