[QUOTE="Black Flash, post: 108053, member: 433"] I used a belt conversion from norvil on my comet. The front "sprocket" I machined in my mill to accept the pd4 with the help of a 25 ton press. If using this arrangement I had to widen the clutch cover with a welded on strip of alloy all way round. If you do so please don't forget to use the commando type clutch lever in your gearbox, the atlas type has not enough lift for the diaphragm spring. While it worked okay I changed back to chain with a self fabricated clutch conversion [yam clutch] with Peter Barker making the cush rubbers for me. I simply changed as I found the cover to wide to look beautiful, so purely cosmetic reasons. Bernd [/QUOTE]
