Changed the original chain & sprockets last night, chain was getting tightspots, and setting the chain slack at the tight spot meant I was getting about 50mm slack at the loose spots!
Used one of those cheap ebay breaker/riviter tools (about 12) and everything went well, soft link flared out and tool didnt break.
I went for JT sprockets (with the rubber damped front sprocket) and DID Xring chain, so about 100 all in including tool.
Hopefully this will last as long as the OE chain & sprockets
Photos below, the front sprocket was very worn, although the rear looked fine
