Hello
I have 4 Rocky over bore piston sets for CB750, size S12 (+4,00mm), part nr. 05-3912. I have not mesured them with micrometer.
The problem is I have only 3 ring sets for CB750, size S12 (+4,00mm), part nr. 06-3912. I have not mesured them with micrometer. Probably CB750 SOHC standard compression ratio. Have to find them somewhere on a shelf and check.
Where can I find one Rocky ring set or a identical set? Any ideas?
I have one CB750A engine in a basket and imagine to make a +4,00mm overbore spare engine. I don´t know if I will need one!;-)
