Hello! I have the problem how adjust idling speed in Honda cb 750 from1975. My bike is working: see movie. My bike hasn't idling speed constantly. After snap the throttle grip idling speed goes higher, down and one more up. Foe example has 1200 rpm. after snap goes higher and down to 1000 rpm. and goes back to 1250-1300rpm. I don't know how to solve this problem. I have changing float level, higher lover, slow jet etc. and nothing. Someone have anyidea where is the problem?!
