[QUOTE="Monkeypants, post: 43174, member: 2708"] That was my plan as well, use the decompressor to ease the load on the starter. Afterall, a giant Caterpillar engine can be started with a relatively small starter motor just by using a decompressor. It was pointed out to me recently that the decompressor linkage on the Vincent is only designed for easing the engine over compression with the kickstarter. If you subject it to impact hammer type loads at starter rpm of maybe 3-400 rpm then additional loads at idle speed for shut down, the decompressor linkage will take a beating it is not designed for. The parts look like a hummingbird's skeleton. So one really needs a starter that is up to the job of rotating the engine without use of the decompressor. Now the decompressor parts might last quite awhile before letting go, and if it the bike is not in daily use could last quite some time, but the point about the relative fragility of those parts made sense to me. If a part in the Decompressor linkage breaks at starting or idling rpm, the potential for major damage in the timing chest is great. I would rather take a chance on having to replace the starter shear pin now and then, or even the sprag. So I'm stuck waiting for Paul Hamon, or doing like Howard suggests, trying to develop my own setup. Glen [/QUOTE]
