sprocket problems

11mm? Bloody hell, that is a huge difference, can't be just sprocket thickness and offset surely? You got pics? Mine wasn't what you would call offset on the R/T. Difficult to just imagine how there could be that much difference. Everything including chain would be out of line. If that is alright and it still fits together safely and in line, then tubular spacers rather than washers would do the job better for you if you could find them or make them.

On mine, thick washers of the type you get on old fashioned galvanised roof bolts 2mm were just right. There is one in the middle of the old sprocket in the pic. The old OEM sprocket was flat as you can see in this pic. Sorry, camera refuses to focus close these days. That strange ring probably did something but the new one didn't have one so ... sometimes I think I should just leave it all alone, but it is working still and is fine ... good luck with yours.

Will take pic in next day or so as bike is not with me at moment, but if you imagine your OEM sprocket, instead of the lip which features on yours outside the bolt pattern, my sprocket is smooth (without the lip) and actually tappers out by 11mm to sit tight against the circlip. Never noticed it till I pulled it apart, however with the tapper so dramatic it will be almost impossible to mount an aftermarket sprocket combo until i work out how to safely space out the difference. I’m not sure the distance can be safely spaced using shims or washers, it will have to be a custom job to get the circlip sitting correctly and allow the chain to run without any tight spots. Its going to be a challenge.
