Ok, since we're on chain care and wheel alignment, I'll pipe up…
Chain cleaning: I've been lubing my chain with PJ1 Blue Label spray...
...following the directions, and I get lots of thick black gunk thrown off, on the engine and on my rear wheel. I've done it directly after a ride when the chain is warm; I've sprayed as little as I could while still coating all the moving bits; I've let it rest overnight to "dry"; I've tried to mop up excess with a rag again and again… all with the same result. Heck, I even let it rest for 4 months and it still blew chunks when I took it for a spin. This particular can, incidentally, says nothing about cleaning. But it does go on clear, so it must be collecting dirt to make it so black.
I'm about to install an o-ring chain, and I'm wondering about this problem. In theory, the internal moving parts are lubed and protected with the o-rings' help, but I still have to lube the outside, and based on my experience so far, I'll have to clean it as well. What's the deal with o-ring chain cleaning? What should I use that's effective and won't kill the o-rings? What's the best way to properly lube the chain without making a mess? The manufacturers directions, at least those of the makers of PJ1, can't seem to be trusted...
Wheel alignment: I haven't properly checked my wheel alignment yet; when I've adjusted my chain, I've always moved my snails the same number of "clicks" each side. When I replace the chain, I'll check the alignment.
Meanwhile, the bike seems to steer true, but when I ride down "my hill" and ease off the handlebars ("no hands"), the bike wants to ease slightly to the right - I can actually lean a bit to the left and have it track straight. Does this suggest that the rear wheel is pointing a bit to the left? Based on this limited information, would anyone suggest a quick adjustment one way or the other?
