Last fall I installed some Bark Buster mounts & handguards (BHG-046 mount / STM-003 guards). Today I got a Kaoko Throttle Lock PN 949728. It took me about ten minutes and I had it on and adjusted; the big washer without the shoulder was the right fit of the washers provided. I just got back from a test run and I like this thing. It isn't cheap, but it is a quality piece, looks stock, and is ready to go at an instant.
