Looks good riedrider

But if the complete set of chain an sprockets is worn it would make sense to put the swingarm off and check the bearings and regrease them. For rivetting you need a good tool. I would not use the two hammer method....

Nope, I wouldn't use the two hammer method, it's not a push bike after all.
Don't think my sprockets are worn, I'm thinking I'll get away with it till winter then I can strip the whole lot off and do it when bike is off the road anyway.
