Just to add a bit of confidence. I used my set of cheap ebay cylinders that had approximately 2000 miles on them already and traveled on route 66 for 450 miles to the Amboy crater. I had no issues. There was one point on an incline I held the throttle open for a few minutes as I was loaded with packing gear to try to keep up with the other bikes. I passed them up on mountain roads though lol.
The top end still sounds quiet and tight no rattling sounds. I ride the bike hard but run premix and timing at 1.8 btc. It's jetted on the fat side so i'm sure that helps.
