[QUOTE="b'knighted, post: 44230, member: 59"] The Comet was built for road use. Vincent's supplied a different machine with a different gearbox for track use. Riders of other makes that used Burman gearboxes don't seem to regard them as substandard. My current 636cc Comet (probably less than 58bhp) runs the best Burman gearbox I have ever used and I think the slight improvement is probably down to the Conways clutch fitted. Thanks John! I don't know how good or bad the Burman was when new but it is my firm belief that the abuse that Vincenteers heap upon them now is due, in the main, to worn clutches. All the Burman clutches I have come across have suffered notchy wear to the basket, hub and the tangs on the plates. I believe that some new replacement pattern clutches use the wide tangs, Lightning friction plate style. If the plates can slide freely on the hub and in the basket the clutch clears easily and grips adequately. With a properly functioning clutch the Burman box is fit for everyday use. [/QUOTE]
