I haven't updated in awhile, and I'll post some pics soon that show how Bro in Law and I have unceremoniously chopped the Roketa frame.
Before we get to that, we pulled the motor apart last night and determined a very strange setup. The bore is a whopping 68.5mm, but the stroke is only 52.5mm; this motor is obviously designed to rev, but that's not our plan. I'm going to try to stuff a 66.2mm crank in out of a 223, which will produce a theoretical 244cc. I'm geeking out just thinking about it.
