I recently bought my bike from a retired Motorcycle cop- so he knew how to take care of it I assume. The bike only had 4200 miles on it and when I asked him about service history he didn’t have much to say In hindsight. so the question is this: what preventative Maintenence should I do to make sure everything is in good running condition? I changed the oil and oil filter and cleaned and lubed the chain but besides that, does anything else really need to be done before 5000 miles? Disclaimer- I’m a bit ignorant to these things. My last bike I just took to the BMW dealer and let him maintain it. The previous owner told me I should probably flush and refill the brake fluid but he didn’t think it needed anything else. The bike runs great and I don’t think there is a thing wrong with it yet but I did notice a loose hose hanging down near the base of the kick stand- it looks like it could be a vacuum line of some sort but I’ve also read the fuel tank has a fume vent line this might be? I’ll try to attach a pic when I have one. Any suggestions would be appreciated- I’m pretty handy in the garage and would like to learn more about this bike so I can do these things myself.
