Got some pj1 chain lube at the harley shop down the road today. The parts guy didn't think they had it, but I found it on a shelf. He said "it's a belt world nowadays". Yep. Anyway, all they had was the black, not the blue. Now I know the blue is supposed to be for o-ring chains, but it says on the black can "o-ring safe". Guess it's a new formula or something, or am I going to ruin my chain using this stuff?
