    Or weld a vertical plate straight up to the rear stud holes. Drill two holes in the plate to mount it to where the rear mount usually goes. I think it would just look cleaner that way.
    I've been using the u-bolts for years now. When I first started out I drilled a couple frames. Looking back I can't believe how dumb I was. I'm pretty sure those frames are in the scrap pile now.
    I use the single u-bolt on a lot of customer builds. I wanted something a little firmer on my personal bike, so I went with the double u-bolt. The pic of it on my bike is not a GOOD pic, but you can kinda see it.

    In order to provide the needed strength and stability for the motor there needs to be a tube from top tube to bottom tube. The tube could have angle brackets welded to each end and held to the top and bottom tubes with U bolts.

    Do you guys think one of these mounts would work in replacement of having to weld anything onto the frame?

    Also do you guys know anything about freewheel jackshafts? Cause looks like thats what im gonna need to do if I want to keep my rear disc brake

    thanks,

    A lot of people are using this type of mount on OCC's and bikes like that. I haven't heard anything bad about them yet, and they've been out for a while.
    As far as a jackshaft goes, that's gonna be a personal choice. Someone on the forum might know a way around your jackshaft dilemma, I got nothin.
