Default Re: REAL 80+ CC Happy Times!

Stroke is not relative. It is dependent on the length of stroke from TOP to BOTTOM.
If you increase the top by the same amount as you increase the bottom, you haven't increased the stroke or anything else, except a bit of metal. Now, if you say you can increase the height in which the piston travels, yet maintain the lowermost point the piston we're talking! (Of course, you'd need to modify the crankshaft and case to match the increased throw...and oh yeah...don't 2-strokes need super-precise intake/exhaust porting!
