Servus, I’m new to the forum. I’ve had a GPZ 550, year 1988 for 20 years, original 50000 km! Last year she started jerking from time to time. I couldn’t find a mistake, I pushed it to the age. But for a few weeks now she has stopped suddenly. This can happen after 20 km or 170 km. This happens sometimes if I want to take the pace back, e.g. from 120 to 80 and then accelerate again. I have the impression she gets no fuel. I stay about 3-5 minutes My workshop did the following tests: renew fuel hose with filter, renew vacuum hose, check petrol tap and tank ventilation, check air filter, ignition system, ignition cable, ZK plug, check candles, check all cable connectors to the LiMa and ignition system, check ignition setting, charge system, (charge voltage 13,4V) battery. Has someone from Eu ch had the same problems? How have these been fixed or can anyone give me a tip? Stupid only that I want to go on vacation at the 30th, so very short notice. Greetings and thank you in advance, Walter
