No, you can do a small modification to your 5 speed starter motor and retian everthing 5 speed. Flywheel, clutch, fork, hydraulics, wiring for reverse lights, x member, front driveshafts etc. Only thing you need is a tailshaft, or get your 5 speed one shortened. Who said they were hard to fit?
Send me a PM if you have one that you need fitted.
