Neal,
Not off hand but I can tell you what they had:
3.625" crank
6.5 Rod
You would need somewhere around a 4.002 bore
They were 9.2:1 with a 38 cc head and .040 gasket
I can check the pin hieght this weekend or better yet if you think you can use them let me know and I'll just send them to you if you cover postage. If you need them and can use them just send me what you think they are worth. I have pins and locks also. The pistons were built by BME and are a turbo piston. I only removed them because I went to a 48 cc head and a fresh hone would've put me at .010 piston to wall clearence.
