Hello together. I need your help please. I have a VF750C magna RC 43 which has been standing for health reasons for several years now. Has run original only 12tkm. The machine starts, but not all four cylinders run correctly. The front two don’t seem to ignite properly, also not really hot. I made spark plugs new. I did not drive, of course, did the machine only in the stand on. Sure there is some glued or so… there is a way with a cleaner, without disassembly the whole machine, to solve that again…? throttle valve cleaner or gasoline additive…? Or maybe also helps a careful warm-up…? I am already grateful for every tip. Thank you and greeting…!
