HArley tranny, Billet rods, Dual springs and retainers, Precision 265 cam, very mild and will give it that little extra umph ya need. Go with standard length rods, Keep the dish in the pistons so you don't have that wild higher compression motor. You need the charging system for the battery and lights so a stock wheel is needed. But the setup above it should run 5500 easily for the road trips and the cam will allow those quick bursts for the extra go when ya need it for passing or just to get on it to enjoy it. You will be able to turn 6500 with this cam and stock wheel. USE a tach and keep it under that and you will be good to go. These motors make great lil bike motors. You don't even need the cam the stock cam with the right spring pressure and head work will turn 6000. But the the etra go is nice to have.
