datz510,
So are you going to weld the one half to the rear motor mount or are you going to leave it as a separate part? Either way will work well just trying to figure out which way you are going to go. I can see this being an upgrade kit for the aluminum framers out there.

I had to weld it to the rear engine plate due to tire clearance issues on my particular install, but whoever is doing the installation could easily slot the U bolt mounting holes to allow these to simply bolt on to the back plate, especially if the back plate is made a little wider in the affected areas.

Oh Man! I have a big Dax on a Schwinn Point Beach and it keeps breaking the mounts and the motor wants to lean out the left side of the frame. I'm loosing it trying to find a way to mount the motor better. I have a bench grinder and the time to make those. Are there some for sale anywhere? I can't risk breaking the brand new motor or bike.

My china engine I'm pretty sure the piston bushing went for it was making a racket and busted my front mount it was vibrating so hard man those bolts were $2.50 a piece.
When I get around to it I'll take it apart. But I'm going with mounting the front mount the way it was meant to mount and extend out the back mount by getting longer studs and putting a few washers between the inside clamp and where it normally sits by the engine.
I thing the clamps are meant to go around the frame for strength. Just getting a plate I think puts too much stress on them M6 bolts/studs.
