Thanks for all the feedback, gents; I think that I agree with Vince on this subject. Getting it just where it needs to get into, is the trick I think that needs to be mastered. Calls for patience to get it right, bead of lube at a time, link by link. So far the one time with this bike I have used just engine grade oil to do this, and I find that while it gets inside, a lot of the bead of lube flows right over the gap and drips down on to the floor. And of course, on to the engine, whenever you run the bike. I need to do what I did 30 years ago, get myself some grease and dissolve it in gasoline as the carrier and get a bead of that in the right place on each chain link. Somehow, I don't see that happening on a moving chain quite as well, so it is a link by link process. But that will still take a lot less time than getting the chain off to do it really the way it ought to be done - for both cleaning the chain and then lubing it. And lubing after a ride, while the chain is warm, and leaving it to stand for the gas to evaporate is the way to do it too. I don't think I can lay my hands on the kind of ready to use chain lube that Vince refers to here in India, that's why I will have to make my own stuff.
What I remember from a book written in the fifties - clean the chain by dunking it in solvent. And then take some grease in a pan, and put it on a burner flame so it melts, and cook the clean chain in it for a while, so that the melted grease gets into all the places it needs to get into. After ten minutes of doing that, get the pan off the burner, fish out the chain after a couple of minutes, and let it drip off the grease back into the pan for an hour, even overnight, before reinstalling the chain.
I never ever did that with my bike 30 years ago, just used dissolved grease into each link with the chain on the bike. Never had any chain trouble for the 30k miles I did on the bike, but then it also had a full chain cover that kept the chain protected from the elements,,,,
How often do people take the chain off to clean/lube it with their Bullets?
