You wish you had old bikes like some of the ones I have. My chain is not dirty at all, there is nothing on it to fling off. Yous was only dirty because you put lube on it to fling off all over everything, sounds like you are the one that needs meds. as a matter of fact a friend of mine was here with another guy and the other guy asked me if I would take $18,000 for my 54 T-110. I said no, it's worth more than that to me. It's 1954 only. They didn't make it in 53 and 56 was different and it's matching numbers. My 64 BMW is also worth a decent buck in it's unrestored condition and I still ride it. If they are junk they are the kind of junk I want not like those junk Hardleys that I have both seen riding with people and the junk Pan I couldn't get rid of fast enough.
