[QUOTE="RossKean, post: 1424346, member: 19880"] ^^^ I agree with Brodie and Skooter. Chains don't stretch and the (apparent?) failure of the OP's blue-dot CCT is the first I have ever heard of - nonsense to say that auto-adjusting CCT can't handle the FJR's rather modest max RPM. (Maybe this one was defective?) While the pins can wear resulting in apparent elongation of a chain, I wouldn't expect to see much on a low mileage FJR - too many 200,000+ mile ones out there working perfectly well. If I am wrong (I think it may have happened once or twice), the shop had better replace the cam sprockets along with the chain. If the chain is anything like they claim then the sprockets are toast. Not so easy to replace the sprocket on the crank. [/QUOTE]
