Back to report... The Protaper bar install went pretty much as expected. I did sand out the inside of the enricher lever a bit, but when I tried to put the oxford heated grips back on, there was no way that was going to happen. Must be a smidgen smaller than stock. I ended up filing down the knurling on the bar, not completly, but pretty much got rid of all the "peaks". Grips went on pretty smoothly after that. They sure felt wider than stock, but about a thousand miles, I don't notice it a bit. The wrist angle is *much* better, and I'm much more comfortable on the bike now. Should've done it years ago! Thanks for the comments and tips!
