M-21 top speed incresed with larger drive sprocket?

[QUOTE So I would suspect the engine sprocket to be a sidecar one rather than a solo one.

Hey thanks for the data AFJ. Also I think you're right about the gearing. There is some hardware on this bike that makes me think that it originaly had a sidecar.
Thanks,
