This bikes motor reminds me a lot of my old Big Red 3 wheeler from way back, the only thing lacking is the little switch/lever near the countershaft for high and low range gearing.



No chance of an old yamaha with similar style motor that had that feature? I have no idea how it really worked but have to think it was a pretty simple gear reduction system.



Its OK to dream, isn't it?

I have an old Yamaha Moto4 a 1986 that has 225cc,a five speed,and dual range with reverse. Something like that might fit into your plans.

The Moto4 was a shaftie. I've been wanting to take one apart to see if this was doable.



There's a remote chance that the output shaft could be similar enough to do some parts swapping.



I think Wayne should take one for the team and sacrifice his.

My big red was an '83 with chain drive, my buddy had an '84 and it was shaft to give a rough idea of the years involved

I have a chain drive Big Red. But I think the Moto4 stands a better chance of donorhood. I've never heard of anyone who's looked into it.

Boy that reverse would be nice. More than a couple of times have I been on a narrow trail that started to go downhill into an area that I thought best to avoid. In those situations I find it difficult getting the bike heading back uphill. Gerry
