Pulled out the spark plug to run a compression test on my newly acquired 700xx and found this; some moron installed a Denso IKH20 Iridium plug, this plug has a 26.5mm reach the correct plug is a 19mm reach! amazingly there appears to be no damage to the piston, also the compression is 110 psi. any comments about that?
