So I have had well over a hundred bikes in my 45 years of riding. When I was young they all had chains, and I did jack squat, I just rode the piss out of all of them. I got into BMW's around 28 years ago, and haven't had a chain since, so I have gotten quite good at final drive repairs and maintenance. I just recently bought my very first brand new motorcycle. A 2018 Africa Twin Adventure Sport DCT. And it has a chain. I have about 200 miles on it now, and it is about 10 days old. I have no idea what to do with this chain. Hard to believe something so basic has completely escaped me. How often should I clean and lube it... what should I use?
