FIRST! MOST IMPORTANT!! CAN YOU HEAR ME??!
Never, ever, ever, ever...try to lube or clean your chain and sprockets with the bike running or in gear...
That said...now, After you put towels/cardboard down under your chain, you should scrubb it with a tooth brush and wd-40...Do about 15 links at a time and slowly turn your back wheel with your hand and then clean the next section. Wipe thoroughly with clean rag
After you have cleaned the chain, blow some air from your compressor down through the rollers and you will see lotsa' gunk come out. Continue the compressed air and wiping with several clean rags until the gunk stops coming out.
Cut a piece of cardboard about 6" X 12". From the middle of the chain on the bottom, slide the cardboard up behind the chain, it will act as a backstop so you don't lube your tire, wheel, floor, etc.
Spray the lube down through the rollers and rotate your tire to move the chain. I try to spray for at least 2 times around the chain. Lightly, again, lightly
spray some lube on the outside plates of the chain, this will help prevent rust and corrosion.
let the chain dry for 30 minutes or so and then lightly wipe off any excess...do not rub or scrub with the towel, you are wiping the excess to try to eliminate the "fling factor"
A tip to help you keep your tips, (fingers)...when wiping your chain while rotating the tire, always wipe the part where the chain is moving from right to left...Away from the rear and toward the front sprocket. And NEVER wrap the towel around your hand
Even when turning the wheel slowly, if you get your fingers in the sprocket, it will bite them off...No lie, no s#!t
Just ask birdman
set the bike down and off for a ride you go...
