Bicycle Motor Preperation And Care

My issue has been dealing with the front motor mount and the larger frame. I just looked at the on line directions. I see to use longer studs. I was wondering if I could just ease the old ones out or this a pulling operation. thus threading the holes.

The stock studs will just unscrew. They still won't (usually) ebwide enough to clear and there are several ways to get around that.

I was thinking if i just do a little filing on the frame without putting stress on the frame this could work. Otherwise add some pipe to the frame that would fit. I looked at that over the weekend and did not like that system. Has anyone come up with an idea?

There are several ways....one is to run the stock mounting studs through a piece of plate steel and then drill holes outside and above or below those that are far enough apart to clear your frame, then fasten it to the frame with a muffler "U" clamp.
