By the second chain change the nut was loose again!

The washer which you have to bend is designed to stop the nut from undoing, if the sprocket nut is loose it wasn't done up properly!

Trust me it was, the washer was all that was holding the nut on.

The first one was loose, that was done up by Suzuki.

I've had the same with a TDM and others have had the same with the SV.

Scotoilers exacerbate the problem though as the chain lasts for so much longer. Even so I'd advise at checking the nut every time you adjust the chain and at the very least every time you change tyres.

I suspect it's more wear rather than actually loosening (as the washer prevented the nut from turning) and riding style may have something to do with it.
