Very Solid System Just got my HD Motor Mount assembly. At first i thought it would not be long enough, but it just fit perfectly on my .7 liter gas bike frame.. I have not painted my bike yet until all my personal up grades are made to my frame. I could had waited to order it with my motor kit but that will be the last item to buy. I know. The kit includes the motor mount, but this one wont have the bolt threads outin the open. Besides. I might all use the extra parts on my old BCA Mountain bike frame.
