Title: M21 clutch choice for sidecar use?
Post by: berniej on 12 February, 2019, 10:47:00
I have a 4 spring clutch in the M21 that I've just built to pull a sidecar. It's slipping and may just need new plates or adjustment.

However, I also have the single spring - AA? - clutch in another solo M21 and wonder if this would actually be the better clutch to use for hauling the chair in which case a clutch swap might be the best way to go?

Cheers,
Bernie

I've lugged a sidecar (two up and camping, flogging up M1,  to work daily) on a four spring with no problems. IOf you are havinmg problems it's down to clutch set up. If you already have single spring you don't need me to tell you these can be a real pita awhe they decide to play up. I'd deffo stick with the 4 spring and just get it sorted.

Thanks Dean - I'll strip and see - probably just needs new plates and a proper setup.
I'll check springs too as the whole bike has spent the last thirty years or so in a bog before the restoration!

Cheers,
