Simple/cheap/effective...1/5 throttle mod. $21.50. Frank told me exactly how to put it together and it works like a charm. Might be insignificant old news to some of you but it's easily the best money I've spent on my bike in the bang for the buck category. It's makes it no sweat to pin it without doing manual gymnastics and makes shifting smoother too. If you don't know what it is or don't have one call him.
