slack

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...

Noticed my chain looked slack on checking free play it was 50mm the handbook says it should be 5-15mm that chain has stretched some in 3000 miles has anyone else experienced this

Just wondering if the manual for the tracer shows the same amount of chain slack as the mt09, or have they corrected it?
