    read my thread... your biggest concerns should be adapter plates, pump efficiency, drive shaft to motor coupling, (remember that the throttle cable gets mounted to the intake manifold ... on a 650 its different... plus are you going to be going performance... you maybe need to re-jet the carbs... etc..

    you have some work ahead of you but its quite doable.!
