The test revealed 130PSI on one side and 100PSI on the other, so the engine has to come down, no point in fiddling with it with a 30% difference in compression.
Good thing i pulled it down because there is a spot of corrosion in the bore on one side, probably from the bikes long storage. So, to re-sleeve, re-ring and keep my Venolia pistons, or to get the power kit and swap them out, then offset the cost by selling the rare Reg Pridmore Kit on to a vintage racer that would love to have some old, unobtainable speed equipment? Decisions, Decisions…..
