No leakage. Then I knew the pistons were getting tired and I was due for an overbore and new pistons. So, I releaved the piston crowns at the exhaust port to increase the timing (like installing a camshaft with large valve overlap on a four cycle). It was a screamer at high R.P.M. but had trouble producing enough power at lower R.P.M. to ride two-up.

I wouldn't do this kind of stuff today but when I was younger it was fun. That's what this is all about - FUN. Have at it. You're making memories that you can tell your kids about to make them certain you are nuts.

Photos please.

Cheers,
