The second chain was totally my fault. I replaced the OEM with a much cheaper non o ring (racing) chain because I was told it would allow more horsepower to the wheel. I replaced it just before heading up to northern California for a 2000 mile ride. I thought I lubed it enough, as well as you can while sitting on the bike, but when I got back there was rust on the inside of the plates and rollers. It seemed that as soon as the rust showed the chain went quickly, had tight and loose areas, impossible to adjust. I believe I paid 56.00 for that chain. I now have the chain kit which came with both sprockets on now, purchased online from a Triumph dealer. I was told by the shop where I bought the cheaper chain that if I had properly lubed it every 200 miles and replaced the sprockets when installed, it would have lasted as long as a O-ring chain. I don't know. I believe the O-ring or the newer Z-ring are a better product, although a lot more expensive. I've never really maintained my chains much, sometimes not lubing for months at a time. I'm heading for the garage today and putting the bike on the lift to change the oil. (and lube the chain if I can find the chain lube)
