Here is a recent picture of my chain. I generally try to clean it once a week. Maybe 2 Have a look. It seems clean. would it be better just to lube it if it is not rusty or dirty? It is dusty... Never had a chain before... Rex
So after you clean it, you never lube it ?? It's the O'rings that need a little lube generally and not the rollers so some sort of lube may benefit the rubber O'rings. If they dry out, the side plates will simply rub against the rings and thus may cause premature wear. A good dry lube like Wurth works well and does not spray all over the place.
Here you go, the Ducati way, https://static.nhtsa.gov/odi/tsbs/2019/MC-10169796-0001.pdf. Andy Edit : Need to say I make no claim to this link, I book marked it from a post on here a few months ago.
I use gear oil SAE80 or 90 works well but I have some SAE140. Put it on, leave for a bit and wipe with a cloth so most of it is gone.
Another vote for Wurth dry lube here. No fling, no mess. I apply after every clean. Clean is paraffin (kerosene to you Rex) with a brush, wipe down, then Wurth. Sometimes I even polish the outside gold links with Brasso
After many years of bike ownership .....using my first can ever of Wurth lube. I'm getting through the can a bit quick though...I apply too much as it never looks like there's enough on due to it being a dry lube ....
I think what you’re asking is if the chain just looks a bit dry but not “ dirty” as such , then should you just lube it ? Personally I wouldn’t. I would still give it a wipe over with paraffin to remove deposited dust and grime in there before you lube it. As there will be some dirt in there which is inevitable during riding , and sealing that in with lube on top will just make it like grinding paste. As for Wurth , I never got on with it to be honest. I find XCP much better and lasts way longer.
Old school, back in the day before chain lubricant and cleaners could be bought in pressurised cans. Automatic chain oilers like the Scottoiler use ordinary oil. This is XCP, https://xcp-protection.com/products/xcp-chain-lubricant/, highly rated by some. Andy
Yes, regularly as my motorbikes are my main transport. So are used daily & cleaned usually weekly then würth dry-chain-lube once dry.
Ref the photo you should lube the at the rollers as well as at the side plates with a lube that is thin enough to get between the roller and the pin, oil will do this or an aerosol lube if it goes on thin and then thickens, I wonder if some of the wax type lubes are thin enough to get between the pin and roller?
Surely the O or X rings are there to stop anything getting between the roller and the pin and to stop the grease that is in there from getting out, thus lubricating the pin/roller interface. My understanding of the purpose of chain lube to be :- prevent the O or X rings drying out, lubricate the roller/sprocket teeth interface and prevent corrosion of the steel plates and rollers. Also my Ducati workshop manual says to clean the chain with paraffin or petrol.
