[QUOTE="kirrbby, post: 185604, member: 3972"] The stock H has a short rod. You just need a piston for a short rod crank, and a new 70 dome. New 70 dome means it will work with the new 70 head...big bearing head. Dratv has the piston(s) [URL]http://dratv.com/kitpiston.html[/URL] I'm not sure how much you have to gain with the newer head tho... More choices of cams, and...it's a newer part and easy to find in good tic. If I we're building that engine back to 72cc, I'd probably bore the stock cylinder, and have the stock head properly rebuilt. A stock H engine is the MOST widely accepted and appreciated engine on a H bike, IMO. Some folks might shy away from a, even slightly, modified engine when shopping for a H. You could probably still do a little porting on the head, add a bigger cam, and run a fancy carb. Something else to consider...I was told that a stock CT cylinder could be sleeved to take it out to 51mm...88cc sleeper..? [/QUOTE]
