01 02 4433 piston super head 54mm 115124cc Ok here is the second part... stroke crank shaftassy 12v monkey gorilla 124cc takegawa Ok here is the deal when this piston was on a 50mm crank the decking was almost flush with the top of the cylinder I mean real close.. Without the 10mm thin metal gasket it would hit the head so it was close... I got the DR-ATV cylinder longer studds and all.. But now the piston is a little ways down instide this cylinder.. The decking is like 2mm away from the top of the cylinder.. So I figured no way the compression would be really low with it like that.. No I didnt put it together and test it or nothing and maybe if the longer stroke increases compression ok then i could see where it works.. But you use the SAME piston for the 2 different cranks. So you stroke it 4mm and if you use a 6mm taller cylinder than before didnt I just add 2 extra mm.. I know that piston with the same head can come up all the way to the top of the cylinder and not hit the head. With the extra travel of the 54mm crank does it increase compression, and you have to run it lower in the cylinder to keep the compression from being to high?? Kinda lost here lol..
