Agree. Kero is recommended. It's just a super light oil. If you're cleaning the chain, it should come off the bike so you can soak it and run the fluid through it properly. For lubing every 500 miles, I slip my hand into a freezer bag and cup the chain, splash a good bit of 80-90W Gear Oil in there and work it all the way into the chain. Follow with a terry cloth soaked with Carb Cleaner and run the chain through it wiping the outside clean. Carb Cleaner is a great cutter and it won't harm plastic and rubber like Brake Clean will. If you don't clean the outside of the chain, it will not only be a magnet for dirt, it also makes one hell of a mess and can even get onto the inner left edge of your tire. You won't know until you need that edge. The real key is lubing it every 500 miles and don't forget. This way you'll get the most out of both chain and sprockets. Juss my 2
