Anybody done a throttle conversion to motorcycle twist grip? I've found the Motion Pro, Moose Racing Gasser ($$$), and Kolpin Handy Throttle. I've seen the Coleman throttle extender also, but that's not what I'm looking for. I've ridden motorcycle for 40 years, and it just seems natural. I don't know why somebody thought they needed to re-invent the throttle control on an ATV, and then pick the thumb throttle?
