Looking for good or bad experiences with aftermarket square O-rings for the CB750 cylinder stud oil passages.
These are supplied with a generic Japanese made gasket set and appear to be intended to be used in place of
Honda # 91310-426-000 O-rings (11 x 2.5), cylinder base and cylinder top deck.
Previous discussions i see from site search leads me to believe the 11 x 2.7 dimension of these should be OK.
Anyone know if these original round were superseded ?
Also, while I'm at it, what success has anyone had with copper coat spray on stock type head gaskets?
Thanks,
Jim
