Stripped RB down to check wear

[davidblythe]

This was a barrell bought secondhand that had holed a piston just under a year ago, cleaned ally off the barrell and just reused it

used a racetour piston with one ring only (to tight to buy another piston, second ring land in a bad way)

not sure exact mileage as speedo broke but possibly 3 thousand miles

performance had tailed off, down to high 70's

only real wear is around the bridges, the ring is slaughtered and very uneven wear esp where the bridges run

assuming the marks over the central part of the piston are where i didnt chamfer the exhaust port (didnt know about diamond needle files then)
