Hi @tricky I'd love to pick this thread up.
It looks like you left off with exhaust mount but never closed the door on the chain drive issue.
I just finished modding my '68 S90 frame and fabricating my version of mount brackets based off your design - thanks. Everything fit up just nicely until I noticed the sprocket on the motor is not centered with the swing arm. It is low enough so that it will chafe. Did you swap sprockets to a larger size / tooth to allow for clearance? I don't think there is enough material to remove from the frame to allow for me to raise the motor to make clearance.
I would love anyones feedback / solutions. I am board line considering chopping the rear and going rigid. Not my first choice as this will be my commuter bike for work. A square 20 mile daily drive. Oh the gas money I will save.
Cheers
