This link shows a picture of the model I fitted. I prefer it to the universal model because to my mind, it looks a lot neater.
Example of Vista Cruise
1) When you remove the rubber grip, you will see the plastic throttle control underneath has longitudinal lands which ensure the rubber grip doesn't rotate without turning the throttle. The lands closest to the electrical switch block (eg Run/Kill switches) will need to be cut off and sanded smooth, otherwise the lock won't fit round the control.
2) On the lock, the right-angled bracket that looks like a U needs to be cut off at the angle so you are left with a tab. That allows the lock to fit flush against the switch block.
3) Because the plastic throttle control has a diameter greater than 7/8", I had to gently sand the inner part of the lock so that it would fit snugly around the throttle control. Make sure you keep it "in round" and do it a bit at a time - you don't want to make it too loose.
4) Set the lock so the thumb-switch is right ergonomically for you and then drill a small hole through the tab and into the switch block. Screw in a small self-tapper to hold the lock and stop it rotating with the grip.
5) Before replacing the rubber-grip, you will need to cut down the flange on the inner end of the grip, using a sharp knife otherwise it fouls the thumb-switch on the lock.
6) Adjust the lock per the instructions so that it holds the throttle when locked but allows the throttle to quickly close when released.
I'll try to take some pics but I'm off to Blighty next week so it might be a little while.
