Also, wanna give me a breif explaination of what Knife edging is and does. I've always heard it but never had it explained.
the ctr pistons are "dome top" pistons creating less space in the clyinder resulting in greater compression and more power/torque. Haven't heard anything negative about them exect the taller piston may cause some clearance issues to the valves...properly put together, clay tested, etc. and it's not a problem though.

As for the knife blading/edging...there's a couple ways to do it but i'm mainly interest in machining the trailing edge and maybe rounding the leading edge. The trailing edge is practically squared off but can easily be cut down to a point shaving quite a bit of weight and allowing it to cut through the oil much more efficiently....

Check out the left side vs. the right side on this pic...


With that done combined with my 8.5lb Cusco flywheel it will rev insanely quick...w/ just a blip of the throttle will give any honda lover a hard on
