Belt drive

Hi Duncan, not altogether sure what's happening with your setup, but I have fitted a Hemmings belt drive to my ES2, exactly like yours then. My problems were with not enough space in the case to allow the clutch to lift without touching the inside, nothing like what you are experiencing. However, you do know that you don't need the mushroom shaped clutch lifter? That would give you some more free cable. Have you set the gearbox-end of the actuating mechanism up correctly to get a proper rotation of the arm? Sorry if I've misunderstood the problem but I can assure you that the Hemmings kit not only can work but works beautifully on mine, light and positive and no oil leaks from a dry clutch.

Have same problem on my Dommi with laydown box Have measured pull needed to disengage clutch completely, which is less than provided by handlebar lever

In my case this is exacerbated by using non standard levers Am working on a solution

I bought one of these

but it doesn't have sufficient advantage in my case

I think that there is a problem with the use of a Commando diaphragm clutch on the laydown (or earlier) box as the operating worm when turning through roughly 120? simply doesn't provide enough lateral movement to disengage.

There is a post on the Commando forum showing what one of the Flanders Branch members has made to get round the problem on his isolastic wideline. It's very similar to what Laurence has linked above but with the possibility to experiment.

Levers with 1 1/16" centres might help a little.

I suspect that a Newby belt kit is probably the best option where a box other than the AMC type is to be used.

Have you checked endfloat on mainshaft?
