Yesterday I hit 10,000 miles on my build. More I ride it the more I like it and am impressed with it. I have done a couple 700 mile days on it, half interstate at 80 and half 2 lane roads. Performed flawless, I have done a large group ride on the BlueRidge Parkway, again no issues, rode in the rain, just be careful with your right hand. It I road it in the 90's and it does get a bit warm on the right thigh.
In AR had to run a couple tanks of 89 and it did fine. The bike is a pleasure to ride, will spin back tire with ease if your not careful.
I know there is plenty of power to break parts like belts and 3rd gear and so on. I do not do burn outs, I do not shift low gears at wide open throttle, or abuse my bike. That said I do ride it hard, and I do use the power.
It has a bit more power than I was aiming for, but that said, this bike is just so much fun, easy to ride and smooth. I'll be taking another trip on her next week. You can build a motor and ride it all over the place or tour on it.
