    I thought the wave raiders had 760 engines but maybe not. 62x would be a 701 engine. Bore is 81. If you go to 82mm then it becomes a 718. Non nikasil walls.

    61x should be a single carb'd 701 engine. You should be able to go quite a bit over. Look up GoupK to find a lot of porting boring info for these engines. You may be able to turn it into a 736 at 83mm easily or a ~780 with sleeves. Pro-X pistons.
