About a month ago there were no exchange Bevel Boxes and only one new item showing on stock, that was at Krazy Horse. The price was in the region of £2500! Some years ago an exchange BB was just under £500 and then it could be just as noisy as the one that came off, as happened with my warranty changed BB's.
My BB is very noisy and has been for the 25,000 miles it has been fitted. I would like to have a go at changing that with a better set up next Winter but trying to identify and source any of the internals, other than bearings and seals, is impossible. Quaife will not release any information, even for a discontinued part, they just direct you to Morgan.......who don't have any stock and don't supply any parts for the Bevel Box.
