I've read many of these Vista Cruise posts and finally ordered one for my '05 ST1300.
I couldn't figure out what the heck you guys were talking about when it came to cutting, glueing, tapping, etc.
Then it hit me... I bought a Universal Vista 7/8", which is totally different from the Vista Cruise for Yamaha or Honda.
The Universal Vista still needs modification to work, just like the Vista Cruise. The Universal Vista is the style with the clamp with an arm that attaches to the slip ring on the throttle grip.
Here's what I did to install mine (Universal Vista) today...
Lay a soft blanket or shop towel over your fuel tank.
Remove the right bar end weight, throttle tube, switch assy, and brake reservoir. Then remove the right bar from the bike. Why? Because there is not enough room to install the clamp between the switch and the clamp for the brake reservoir.
Once the bar was off, I drilled the same size hole 1/4" to the right of the existing hole under the bar. This is where the lower half of the switch indexes to the bar with a tab. This will allow the whole switch and throttle tube assy. to be slid to the right 1/4" to allow room for the Universal Vista clamp to clear. Note - you will drill slightly into the internal weight in the bar.
Clean up the mess from drilling, and remount the bar, brake reservoir, switch assy, and throttle tube. Leave the end weight off for now.
Loosely mount the clamp between the switch and brake reservoir clamp, and install the arm to the clamp. Slide the slip ring and rubber over the throttle grip. I discovered the short screw was too short, and the long screw and spacer put the slip ring too far onto the grip. I have containers full of various spacers, washers, etc, so I found a nice aluminum spacer about 1/4" to go between the arm and the slip ring, and I had to trim the long screw down about 1/4" to make things perfect. I also installed a small #8 brass washer on the head side of the screw where it enters the thumb tab. If you overtighten this screw, you will notice that the thumb lever compresses, making it harder to operate.
Ideally, I would think the arm should be below the kill switch, but where the wiring exits the switch prevents this from happening without chafing the wires. You can put the arm over the kill switch, but then it's a bit of a reach for your thumb. I installed mine so that the arm crosses directly over the middle of the kill switch so that the top and bottom of the kill switch are still accessible.
After aligning everything to your taste, tighten down the clamp and the arm. Square the slip ring on the grip and tighten the set screws. With the Universal Vista, the grip does not turn inside the rubber; the rubber/plastic assy. turns within the metal slip ring. No need for sanding the rubber, etc. Fine tune everything and then after you are satisfied, install your end weight. Make sure to put a drop of quality threadlocker on the bolt for the end weight. Make sure the Vista operates smoothly first, then install your end weight. If your throttle starts to bind, loosen the end weight a bit.
I am hoping to road test my masterpiece tomorrow.
I hope I helped someone else out there who was as confused as I was. Make sure you are reading the correct tutorial for the correct cruise model.
I will attempt to post some pics in the days to follow.
