[QUOTE="oexing, post: 105752, member: 1493"] Well, I was alerted by tales of " slow" gear changes on the Vincents. So when I found that gear lock detent plunger I was quick to realise I did not like the design: When trying to rotate the camplate the plunger gets a lot of side load from spring action pushing it into the v-slot that prevents the camplate from turning. So the plunger gets high side load when it has to lift a bit and side load in its bore creates quite some friction - that I would not want in gear changes. Also the pointy top of the plunger is not great but essential as there is no fixed orientation for it in the bore. In the end I designed a lever and only a spring is in the old bore for preloading the lever. So I am quite positive about this for getting smooth gear changes. Sure, this will be a bit more agricultural than on smaller bikes when you look at the massive gears inside which I guess would easily handle 200 hp no problems. Now compare this with gears inside some Ducati or the like !! Vic [ATTACH type="full"]26508[/ATTACH] [ATTACH type="full"]26509[/ATTACH] [/QUOTE]
