Manual trans minibike project

[sparkwizard]

Not mine, but I want a transmission. The guys at Cars and Cameras build some wild and expensive projects. Look at the kickstart BSA transmission.
Enjoy!

watching the video now are the transmissions stock to those engines?

Yes but you couldn’t tear them up if you tried….ran one on a Panhead for years…

The guys in the video mentioned Harley divorced transmissions, they said they are too big for their project.

That one looks like it has an internal clutch. I don't know what else that lever could be used for.

That is a BSA A7/A10 transmission, the lever on top actuates a rod through the center of the the input shaft to operate the clutch, which would be attached to the other side of the case. the input shaft goes through the center of the output shaft so the clutch and output sprocket would both be on the other side of the transmission.

I love the idea of a manual trans on a minibike. I never knew where to get one.
Maybe this spring, we will find some money while we plow and plant the gardens.
