https://sites.google.com/site/1983hondacx650c/home/component-information this page has a little of everything!!
the unit for the cx 650 custom is at the rear of the battery best to take the seat off. A cx 500 custom is in the head light. Some times the 650 has had a none factory mod and put in the head lamp
87 octane
10w40 no need to get the special motor oil, it just costs more and does the same amount of work..
drain the old oil from the engine. there is a drain plug attached to the oil pan that looks very much like one on a car. as that is draining into a container, remove the oil filter from the front of the engine. it is the little aluminum colored bump-out next to the clutch cover. remove the old filter and replace it with your new one. put everything back together and re-insert your oil plug. then fill it up with a high quality motorcycle oil (regular oil will not do the trick because you have a wet clutch in the bike). ensure you don't over fill the engine by checking your dipstick (again, much like a car) and now your all set to ride again! good luck
