Throttle locks

Anyone know of a cheap throttle lock? I had one called a throttlemeister that cost somewhere around $130 but it vibrated off somewhere in Louisiana on me and thats a loss I'd rather not repeat. I've been using an o-ring wedged between the grip and the throttle housing for the time being as this bike will put my right hand to sleep after 20-30 minutes.

I bought one for my softail about 6 years ago...worked Ok but was a bit pricey at $200+....still using it though....just can't remember what it was called. Hard to find a good one cheap....I need to find another one for the wife's bike soon so I will post what I find.

Vista Cruise is hard to beat for me, but you might have to drill the throttle housing if that little tabbed one won't work for you.

These are supposed to help with that, just got one yesterday and my feelings are mixed so far, but it's cheap: http://www.rockymountainatvmc.com/p/49/61/188/1232/-/-/166899/CrampBuster-Cruise-Assist-Standard-Wide-1-1-8%22?ref=gmc&gclid=CL-mmZaNurICFQmpnQodG2YAMA

Thats what I'm looking for. Thanks.

Just have to find out what size bars I have now.
