[QUOTE="oexing, post: 179533, member: 1493"] I don´t know about critical sizes for the Burman clutch mod. But I would not think you´d need Maughams for fitting a Jap clutch onto a Vincent. The complicated part is the splined adapter for the clutch hub to go on the input shaft. That would be a EDM wire cut job from a freindly tool room company . You just give them sizes of spline and shaft o.d. and tell them to cut half a millimeter deeper into the o.d. size so as to get full depth of spline from wire cutting. The wire has something like 0.2-0.4mm diameter so you´d get radii in corners - bad for having full depth of splines. So that is why to tell them to cut deeper , not just up to 1/2" shaft o.d. like on twins, don´t know about Burman sizes. I like the Kawasaki clutches for their needle bearing to sit on the input shaft. They are 25mm by 42mm , so have the inner race opened to 1/2" . The Kawa spline will not fit, so maybe you have to turn an adapter from good steel and fix that into the clutch basket after spark eroding the spline. I did that by having a left hand fine thread on the adapter and same in the alu basket, glued in by Loctite 270 or 648. On the twin it is a close fit under the primary cover, unless you cut out the wall for a very wet clutch. So a few links to Kawa clutches for having an idea: Vic [URL='https://www.ebay.de/itm/145159125199']Kawa clutch[/URL] [URL='https://www.ebay.de/itm/394190854585']Kawa set[/URL] [URL='https://www.ebay.de/itm/394190854585']Kawasaki[/URL] [ATTACH type="full"]62183[/ATTACH] [ATTACH type="full"]62184[/ATTACH] [ATTACH type="full"]62185[/ATTACH] [ATTACH type="full"]62186[/ATTACH] [ATTACH type="full"]62187[/ATTACH] [/QUOTE]
