older 250r motor in 300ex frame

[atom]

i know that the sprocket is on the wrong side, but is there any way that this can be done? using a different axle? any info would be appreciated

use the swingarm/axle combo from the 3 wheeler as well.i wouldnt mind finding a 84 model as they were the most powerful of the aircooled and doing one myself

so i can just swap the swing arm from the 3 wheeler and it will fit right up to the 300ex, same bearings and stuff

You'll probably have to do some fabricating to get the swingarm to fit onto the 300ex frame. Doubt that it'll bolt right up. I'd find the swingarm you are going to use and take measurements on it and line it up and see what needs to be done.

Btw - Where in WI do you live?
