"I know what your thinking and the answer is the GT750 engine is way too big for that frame without hacking it to pieces."
Yes, you sure did know what we were thinking PTW!! <LOL>
TZ, I'm a little confused by what you stated.... that there is a power gain up until about 8K....but then said it's a problem though because they never see those sort of revs on the street.....so why would there be a problem? Sounds like a perfect match!

You never did say if the wider ports expose the transfer opening in the piston ?

Jeff, That wasn't what I was trying to say.jeff kushner wrote:"........

Running a single ring on a 2 ring piston typically loses power compared to both rings up to about 8k revs. Above 8k the single ring makes more power than a stock 2 ring piston with both rings fitted.
Is that clearer?

That's what I guessed you were trying to say but I don't like to assume that I know what someone is thinking...it's easier just to ask.
