I bought a set on ebay, internal throttle + internal clutch. It seemed like the seller got it on a poker game or something. He knew nothing about it... And I mean - nothing. I never got enough time to seriously think about installing it. Plus, my handlebars are kinda short, dragbar-like. I think the cable (specially the clutch cable) would bend under some pretty hard angle at the middle to reach under the tank. It looks darn cool, that's the truth. Keep us posted if you get to do it, please.
