Talking to a buddy last night at Bike Night, and he was telling me he has 24,000 miles on his original chain (he rides a Hyabusa), and has only tightened his chain ONE time in that entire time, and he rides it hard. Now, I will say that his chain is the cleanest I've ever seen, he is very meticulous. But he says his dealer originally suggested he just leave it be, that the chain will stretch only so far, and then no more. That basically, if you keep tightening the chain, it keeps stretching. Anyone ever hear of this theory or try it. I have to wonder, if he is just super lucky, or maybe this thoughtline is valid. His bike puts out a HELL of a lot more power than our bikes, and I looked at it and his sprockets and both look very good. He said he is getting ready to finally replace it, but is shipping out to Iraq next week(private security firm), so is just going to sell the bike and buy 1 or 2 when he gets back (why not, it's $250k for a 6 month job, former SEALS/Green Berets only!) Anyhooo, this has my curiosity piqued...
