A few people are asking about chain final drive and I have offered to do one or two but the big drawback is this. At the moment, I cut the teeth off the old final drive belt sprocket to make a chain sprocket carrier which means you can't convert back without buying a new belt sprocket and I guess the price would be prohibitive - if you can get one at all. I am hoping to get an old bevel box or sprocket to use for identification of the involute spline so that I can make carriers from scratch. Anybody got one they don't want?

There are significant advantages to chain drive :-
1/. The chain only costs about £100 and can be replaced without removal of the swinging arm and bevel box.
2/ The sprockets are cheap and easy to change which also means you can change the overall gear ratio.
3/ There is less conflict between chain alignment and vehicle centre line alignment - a chain will allow for small misalignment.
4/ The drive belt will track differently on over run braking and is difficult to keep quiet, especially if the sprockets are showing signs of wear. - use washing up liquid to quieten it if you want but it sounds wrong to me.

Watch this space - as they say.
