Thanks all,

I think I may try and flatten them out and if that fails I will stick them on the walls like a trophy set of antlers.

Looks like the British custom ones must have a bit longer on the throttle tube as their brake reservoir isn't hard against the collar, but you are right friar John, going for a 1" bar would be the smart choice to avoid much of the same.

Wasn’t until I started taking of all the cabling and fitting the controls properly for doing the measure for the brake lines that I noticed the problem.

Hopefully this will save someone else making the same costly mistake.
