OK, I tried a Cramp Buster on my 04 Thruxton with Clip-Ons... Put it on at the store, and 36 miles later when I got home it came off and never went back on again. It was uncomfortable for me, as I'd lean into a turn it would cause me to roll onto the throttle. I use one of the Go Cruise Throttle Controls, BEST $20 I've spent on my bike in years!!! Very simple to use, won't keep the RPM at the same spot forever, but long enough to adjust your clothing, warm your hands on the top of the engine, stretch, whatever and keeps you from having a death grip on the bars... Highly recommended.
