Hi can anyone tell me why the pistons in a Yamaha cs3 have cutouts halfway up the side of the pistons. I have just removed the barrels on mine and the pistons dont have the cutout I think they are wrong for the bike, I think this is stifling the performance. Any ideas people. Thanks.

Hold on, have we got a Hollywood A Lister on the forum?

Are you doing another anchorman film? 

Nah, 'scavenging' for answers..
