[QUOTE="davidd, post: 53183, member: 1177"] Aldeburgh, Nicely put. I had the exact opposite problem in my racer. The boss had a large void in it all the way to hole. This void ran under the seal on the paper filter so it was feeding unfiltered oil to the crank. The problem in both cases is that the felt filter seals on their outside diameter,that is around the boss, against the wall of the chamber, while the paper filter seals on the small diameter of the tiny boss . On the twins this area of the boss seems to be fine, but on the Comets the shape of the boss is "hit or miss." Although the paper filters work on many bikes, ultimately the boss, which provides the seal, was not designed or intended to provide a seal. It is unfortunate that the makers did not glue a large rubber ring (thicker than the boss) on the end of the paper filter so it could seal on the rear of the chamber wall per the original design. Alternatively, one could make a banjo bolt that reached further into the oil chamber that would seal on the small diameter of the paper filter. David [/QUOTE]
