Hello,

I'm looking for Popy 836 piston ring.

What I can use, and where I can find them?

With best Regards,

Julien

Is that Pop Y as Pops Yoshimura? Did he ever make 836cc? I thought the biggest he offered was 823cc. Bill

The bore is 64.5mm

Julien, Like Billy says, 64.5mm bore gives 823.504.8cc.

64mm PopY is 812. It uses 1.5, 1.5, 2.5mm rings. These are stock Honda CB350 twin rings. 1968+. 64.5 would be those +2 and 65 would be those +4

Hello,

You re right . I stripped yesterday night the bore is 64.5. Sorry for my confusion.
The Piston are Popy casting.

Regards,
Julien.

Julien, as Jerry says, the CB350 twin is 64mm bore so you would need two sets of 2nd overbore size (+.50mm) if indeed they are 1.5 1.5 and 2.5mm thick, check them.

If they are your problem is solved.
