I just recently purchased a 1976 CB750K as my first motorcycle and was trying to perform a simple oil change (or so I thought), but I cant seem to remove the bolt that holds the filter on or the oil drain plug on the bottom of the engine. Any help is greatly appreciated?
ETA-Got the drain plug...
What are the differences between the 79-82 F,C and K models. To my untrained eye it seems that they just have different styling but I was wondering if the frames are the same, if the tanks and seats are interchangeable between models and if there are any engine differences? Thanks for the help
