Install the brakeaway I got from another member here and it works flawlessly. Way smoother than the vista cruisers I had on all my previous bikes. It was a bit of a pain to get adjusted correctly but wow was it worth it.
Your thread title is a little misleading in that the BrakeAway is a throttle lock and not a true "cruise control". I have one too and like it a LOT. As far as fit, finish and functionality go, the BrakeAway is tough to beat. Expensive? Yes, it is; even more so than some true cruise control units. But if you're just looking for a quality throttle lock, the Breakaway is worth the price....IMHO.
