I am thinking about using a legends thunder roadster as a basis for a DM car for SCCA Solo autox. The 13b is allowed in DM and the thunder roadster comes with yamaha 1250cc engine which is not allowed in DM but the transmission is not disallowed.



I was wondering if there is a way to mount the 13b to the yamaha trans or any other motorcycle trans like the hayabusa trans?



If nothing else I know I could use a 2nd gen 13b with the stock 5speed for this car, but I want to keep the weight down and keep the fast shifting motorcycle trans.



Any thoughts?
