mad OK just learned you dont hit the backspace key just as you finish typing....30 min all gone lifes to short to do it all over......again..... cry

I did have a heap of numbers typed out in a nice format for your parusal and comment but at the end of the day it worked out to 1/2 thou oval @ 1cm with 3/10 of a thou taper @ 6cm with 1/2 oval there too. Piston clearance works out to 0.0056" with 8/10ths piston ovality. The wide groove was barely there and I wasn't able to measure a difference.

Whats the verdict Grumpy? might be a bit slappy? just re-ring using the old piston?
