This past weekend, I installed a NEP throttle keep on the Scura. For youngsters who've never heard of NEP, they date back to the 80's. They are currently manufactured by Sound Off Recreational and available through several sources. http://www.soundoffrec.com/Default.aspx They are amazingly simple and effective. It is essentially 2 half circles that go around the throttle tube. A lever compresses the circles together and keeps the throttle from moving. Here's the top side view with the lever.
