Hello fellow sufferers, short description of the problem with my “Karla” (GPZ600 R BJ 1986, ZX 600 A). “Karla” jumps without murmuring in the morning (even after colder nights) flawlessly (apart from the usual choke problem).If I take my darling to the bun, she no longer jumps.Benzinhahn stands on “ON”. Must then wait about 30min and hope that she then starts again.If she does this, she runs perfectly.When I have reached the home yard again,… …….. “Karla” from,………………..trying to start again,………………………………..nix is!!!*smack* 30min everything Roger starts again. Have now already renewed the spark plugs, the reperature set for the “missing……..” petrol tap lie here when I fell yesterday on the subject of underpressure. What can the jewel have? Carburettors were syncronized 1000 km ago. Can anyone give me some useful tips?
