As for a tool for closing the master - I usually let the dealer do it. My AL7 is coming up to 15000 miles on its original chain and I think I may be able to double that. A rivet tool kit costs £30 (and up) so I suppose it would make sense to get one, I just never have.

So, after all that babble, I don't have a suggestion, sorry
