Hi John, thanks for the heads-up. The bearing track is only 6.8mm wide, so 9mm rollers will definitely be a problem! I assume the bearing from the AJS Matchless club is the correct spec. I’ve added a note to the guide.
Hi Chris, you need to take off the primary drive cover (left hand side) and have a look. It could be clutch slip or a number of other things. If you have Facebook, probably best to ask a question in the AJS & Matchless lightweight singles owners group. Good luck!
Hi Malcolm, sure thing! Feel free to give me a call - happy to help any time…
