Just installed a Vista Cruise throttle lock to the 9R. I'm not entirely impressed. For one it needs a lot of pre-load tension to ensure that it grips solidly when locked on, and the preload interferes with normal throttle use. Second thing is that at highway cruising speed, I only need to have the throttle barely cracked open... which is the least controllable point in the throttle's range - especially because the vista has a small bit of play - so the throttle rolls off a frag. Any other experiences?
