Installed a finger throttle on my x4 last week. I recently injured my thumb with my x4 and also broke one of the tabs on the thumb lever. That's when I remembered that my 04 GTX that I cannibalized to build my 4tec boat came with a finger throttle. Well now I'm trying to get used to the finger throttle, and must admit, I'm not sure I'll be keeping it. After 14 years of riding with the thumb lever, having to rework the brain is proving to be dangerous. I'll forget and either floor it or let off at the wrong times and strange scary things happen. While it has almost ruined my swim shorts, I did finally (accidentally) manage a full 360 :hurray: Also, the throttle doesn't seem to give enough slack to allow the butterfly to fully close. My idle RPMs are at 2500 now lol.
