I posted this on a board in Australia but thought there may be others that might be interested.
I wanted a throttle lock but did not want to pay the $120 plus cost. I modified a simple tap fitting and it works better than it has any right to - on my bike at least. I have a 7/8" bar and it needs Barkbuster guards or similar to work. It took me about 15 mins to mod the tap fitting and fit. I did not take photos before I started but if this post does not make sense I could take it off the bike and photograph the individual parts. I use a cramp buster as well and this makes it easier to engage the lock but is not essential. My description makes it sound hard but it is very easy.
I found a barbed tap fitting in Bunnings (large hardware chain). I think they might call it a "barbed hose nut" but it is a nylon piece that threads onto a garden tap and would allow a permanent hose to be attached. The important features are that it has an insert to allow 2 tap sizes to be used and that it has the large raised wings on the knurled ring. It has 3 pieces - the main body, the insert and the barbed tube - throw this last away. I used a belt sander to narrow the body and insert so that it was about the thickness of the spacer that sits between the grip and the Barkbuster. I used a kitchen knife to enlarge the inner hole big enough to slip over the bar end. I then temporarily replaced the spacer with the new part and marked where the metal arm of the Barkbuster crossed the insert - this outer lip has to be notched so when fitted the insert cannot rotate. 2 cuts with a hacksaw on these marks and then grabbing the lip between with pliers and a neat notch is formed.
When fitted the raised "wings" on the body allow you to rotate it anticlockwise and press up against the grip. I use my ring or middle finger. Conversely to disengage a quick flick and it loose. It does not engage accidentally and it does not gradually slip when used.
I am happy to provide more detail if the above is not clear.
