After an extended powwow with Denny, we have figured how to get our Berzerkeley back on track. The plan involves retaining the front gearbox, as we think the design is quite sound; the gears are rather large and the case itself is quite thick—much thicker than it needs to be.
We also need to make …
Why not just use the factory bike trans and make a single-gear reverse-rotation diff? It seems like you are over-complicating this part of the build.
What about the 90's goldwing setup? Not quite sure of how it worked but might be something to look at.
Hey guys. Not sure if you have heard of the Geo Metro Gnome. It's a motorcycle powered Geo Metro that we race out here at west coast LeMons races. Here is a link to some coverage:

We are using a bit of a different setup but the two cars have a lot in common. The #1 issue was getting enough links into the chain. Your setup looks great but that super short chain might have some trouble overheating and thus stretching very fast. We solved the problem on ours by running twin chains with a smaller pitch. If you would like to get the contact info on the guy who made the rig for us on a budget, feel free to email.
