    These kits are normally designed for a steel frame with thick walled tubing. Your Felt has big diameter, thin walled frame tubes. Are your frame tubes collapsing a bit, causing the motor mount to loosen?

    Steel won't (unless it's thin wall 853 or so). Aluminum might.

    I figured that on aluminum there was a thread covering running 1/2 round (short)lengths if steel pipe under the clamps too stop the crushing,,,I was just thinking the crushed in ring would act like a weak point like threads do on a bolt

    I think the OP is saying he's using these motor mounts designed for Felt frames

    AMPT is the guy who is (was?) developing an aluminum frame with a built in tank. Interestingly, Iv recently saw what appears to be the same frame being sold by Grubee.

    He's also marketing those nifty offset mounts. If your mounts are sliding around, you could perhaps drill them and the frame and insert a roll pin which would index the mount to the frame.

    Why not just buzz a hair off where the clamps bolt together with a belt sander? just enough so they dont touch when bolted together on frame.

    Hello felt masher, you have the wrong sized mounts, felt has two down tube sizes. They will send you the right ones. They are aware of your issue and have already mailed them to you
