Try a contra or 070, then bang an 090 pot on it, I have

This works in that it physically fits on the 070 crankcase, and on the Contra if you mod it slightly, however the clutch will end up giving you issues.

 

The only components which are different between the 070 and the 090 are the pot and piston, starter and clutch. The starter is OK if left alone, so long as you can pull it over. It does put slightly more stress on it, but doesn't have any noticeable effects that I'm aware of. The clutch however does give you a longer term issue as the 070 (and early Contra/Lightning) clutch couldn't handle the torque. The clutch was uprated to the six-shoe version, for the Contra S/090. This can still be obtained, but is expensive (about £180).
