Thanks for all this input - I'd kind of taken the chain for granted. I adjust it and lube it, only cleaned it once, a lot of miles ago, and I guess it's time to do it again. I bought a grunge brush the first time, which just seemed to make a grotty job more crappy and difficult than it needs to be. I'd used chainsaw oil as an emergency measure before a long trip and the bloody stuff was everywhere. The dry lube was my plan to keep the wheel etc cleaner, but I guess it makes me neglectful of chain cleaning duty.
I seem to be working my way round those snail cam notches pretty rapidly. It's an aspect of motorcycling I'd klind of forgotten about. That said, it's good to have
something to tinker with on these damnably reliable machines...
So is there an O ring chain available for these bikes? Do they make for happier transmission?
