Got a replacement Namura piston in and it's not like the OEM model.
It's got higher intake windows, reinforced crown, and a place milled on the exhaust side of the crown that advances the exhaust.
Anybody ever seen one or used one before?
We cleaned up the ports on the cylinder and after bead blasting, will install.
This thing looks like it will not have very much bottom end but will probably scream.
My buddy Sam told me the old Bultaco guys would have pistons like this for top end flat track racing.
