In what way is copper better than aluminum? Seems like the aluminum gasket works fine - IF you retorque it about 3 or 4 times from new.
Some this idiot (ME) forgot to do this yesterday before a long ride. After installing a new head gasket after lapping the head last week, I forgot to retorque it when it was cold. On the way home my bike was down on power, going all funky noise time at high RPM, generally just limping by the time I made it to me street - acorn nuts were just about LOOSE!!.
Does copper and or sealant help with this retorque regime?
