I figured I wouldn't be out much to put some canning wax in a jar and give wax a shot. I recall joking with the mechanic that I would see if I could get 2,000 more miles out of the chain before replacing it. I'm at 1,226 miles since then, still working at least as well as it was in April. I think I'll get the 2,000 miles that the mechanic laughed at.
