Last night i took the motor out of a trashed bravo and lodged it in place in my 200m roller..the motor fit good with lots of clearance for the motor and carb.. i was wondering about the clutch and saw a centrifugal clutch at a industrial parts stor. They have the correct size for the shaft off the motor and everything else I would need . It would slide on in place of the primary clutch on the motor. The clutch is used oftenon a go kart or a simmalar thing . When it engages it engauges on a 12 tooth sprocket that is the same the front sprocket on a trike. and with the right motor mount the chain will allign with the rear sprocket. This would be a project for the fun of it. Anyone wanna add to this or make any suggestions would be great.
