I just spent three hours cleaning my chain. First wiping down the chain with Kerosene, then cleaning each interior chain link with Q-tips, especially to get in-between, links to remove crud, then used a paintbrush dipped in kerosene to get crud in between inner and outer chain links. Seems like it may be faster just to remove chain. However, looking in Haynes manual and at bike removing swing arm seems like a big project. Is it?
