Best Way to clean gunk off chain...
Brake/Contact cleaner works awesome!! *******DO NOT SPRAY DIRECTLY ON THE CHAIN!!!********* it is very aggresive and can damamge the o-rings, spray it on the rag and then wipe
i think the best way to clean it is with soap and water (thats what most manuals tell you) and try to do it pretty often, like every second tank of gas, also dont forget to lube it when your done.
I have used two products that seem to work great they are Greazed Lighting and Simple Green. They are not suposed to damage the o-rings in the chain. Greazed Lighting works the best for all areas brake rotors, motor, and road tar.
NO GAS!!! Kerosene or diesel, sure. WD-40, maybe. But gas, never. This is another topic (like which is the best oil) that is never ending. It's like asking what's the best way to wipe yer a$$ -- there are many ways (none include gas I hope) that work well but I can't say as any particular way is best. The most important factor is that you keep the chain clean with the proper slack.
I try to go for a little run to warm the chain and then degrease it w/ WD-40, prob. not too dissimilar from what you're doing now. By warming the chain, you might be able to get more cleaning solution into the chain. I spray it on and use a combination of shop rags and old toothbrushes to remove the grime. I'll do several passes to get all that junk off the chain. A little bit of the debris gets on the swing arm and sprockets so I'll also be sure to soak them w/ WD-40 also. Rinse thoroughly and then lube w/ Honda Pro Chain Lube (blue/black/white can). I'll also lube the chain twice over, so I do get some spin off, mostly on the lower fairing under the front sprocket/side-stand.



dont let it sit in your garage
