When you spend 24-hours in the saddle during a competitive Endurance Riding event, a throttle lock is almighty useful to give your hand a brief 20-30 second rest to get rid of the "tinglies" by getting the blood flowing again. I don't use it except for that purpose only.
Installing one on the K8 was a complete ass-pain to do, but the results were actually quite excellent.
Final Install:

I used the Vista Cruise lock for the Honda 2-cable throttles, which has a small "ledge" to it:

So I needed to grind off this ledge... you'll see why here in a bit:

Now for the ass-pain part.... the K8 throttle sleeve has several large ridges that are used to help retain the factory grip in place... these ridges have to go.
Here is a photo comparing the OEM throttle grip with the BMW "Sport Grip", which is about the finest grip you can use for spending hours in the saddle at the vibe-prone 4500-5000 RPM range on the Busa. These are the de-facto standard in the Iron Butt-riding/Endurance Riding scene:

Since I was swapping the OEM grip out for the excellent Beemer grips anyway, I had to grind these two ridges off the throttle sleeve....

There is a third ridge on the outboard end of the throttle sleeve... off it went, too....

Now this next step you don't want to dick up.... drilling two small holes to pass through a small retaining bolt that will affix the throttle lock in place. One hole through the throttle lock, and it's attending hole in the throttle pulley housing. There is more than enough room within the housing to hold the small bolt you will use here. Remember.... measure twice, cut once! :thumbs up:

Now you can mount up the Vista Cruise and adjust away! I ended up not using the nyloc bolt you see below, rather, the washers and small bolt only. The fastener cut its own threads into the plastic, and has been holding steady for several hundred miles now.

The BMW grip is just a couple millimeters longer than the OEM stock, so I needed to add a washer or two on the Bar End Weight so it would "stand-off" from the throttle grip and not rub up against it.
That's it! :thumbs up:
Like I say, installing the Vista Cruise on the K8 is not the trivial job it is on most bikes, but it's well, WELL worth the effort if you are serious about Long-Distance Riding. Any questions, fire away.... :smoke:
