Hi all, got a CB400f a few weeks ago and been having lots of fun riding around enjoying the dry weather seems like a good old bike cam chain chatters quite a bit and won't adjust and she misfires a bit at idle untill the engine really warms up but apart from that all seems good, registerd as 1977 but I'm not sure if YOM is earlier than that, I'm hoping to find a website where I can check frame/engine nos to verify YOM. will update my profile and post up some pics soon.
