got my kit, mounts too big?

[pickled]

I've searched on this but it seems most people have issues with the engine mounts being too small for their big tubes, I have an old bike so the problem is reversed -- the mounts are too big for my frame.

is this common, is there an easy fix? it looks like it might work if I put enough inner tube wrapping in there, but that seems like it would lend itself to a weaker mount overall.

any tips would be greatly appreciated. thanks!

Need pictures, would help determine the options.

I'm sure you could shim it out nicely with something besides junky inner tubes (which will quickly disintegrate.)

Lead sheet had been mentioned. Soft copper? Aluminum? Some other polymer?

lead sheet is an interesting idea. I wonder how that will do with vibration in comparison to rubber?

I'll see if I can get a pic or two shortly

I would go with the lead sheet
you would think it will help with vibrations as well

I've never used lead sheet as a spacer....would it be too soft with engine vibration?
Personal recommendation at the mo would be aluminium.

good point, fetor !

I never have been a fan of the 'cast' mounting clamps. The 'stamped' steel straps always conformed better to the bike frame, for a more versatile fit.

Dax has some motor clamps on their site they claim are unbreakable.
