The clamps were too tight and started to dent the tubes, but they are very small and hardly noticeable. So I'm not terribly concerned at the moment since I already have some other frame repair/repaint planned.
I've already got some lower bars mounted and I think they'll work out great. I've got the head removed and getting the exhaust ports fixed up so I can't really test the new bars yet. However, I've got similar euro bars on a 73 cb750 that I absolutely love, very comfortable.
Before I revert to the 19, I need to know what is the general consensus on Avon roadriders? Or what other tire would be a suitable (yet economical) set or tires to buy. I don't plan on racing or anything but may attempt a +1000 mile trip at some time.
