Oil change on the gsxs1000. 3600 miles already. Rotella with wix filter. Oil was a bit darker than i expected coming out, but there was minimal black residue on the drain plug magnet. Also cleaned and lubed chain. There is already rust on it, which angers me...must be from riding to work in the rain the other week. Have been cleaning and lubing chain every other tank of gas (300 miles or so), thought that would have been often enough. Really hosed it down with the KLR this time, maybe I'll go to lube every tank, clean and lube every other.
