Moin, I know this has been asked so many times, was written, but I have read all of them and there was nothing suitable about it. I have a Gpz 600 R,Bj. 87, this just got Hu and I drove them home from the dealer, wanted to start them again 2 days later and the buck didn’t start. The engine spins, also tries to ignition, after longer “noodles”, the motor starts to crack more strongly at the ignition attempt (as if the driving times were changed!) Troubleshooting started, but slowly I don’t know any more. I’ll write what I’ve already done/tested everything. 1. Carburettor disassembled and cleaned 2. Candles are/are new 3. Candles removed, plugged on the candle plugs and lit, on each candle there was a spark to see 4.Control unit/Blackbox changed/exchanged 5.Zündpickups inc. Adapter plate changed( from the old one of the pickups had no resistance value, is tested with the new one and i.o.) 6. 9.Coupling switch bridged 10. fuses in the Junction box looked (the 4 pieces) 11.Startpilot sprayed into the carburettor at the back, it almost does not work, gave 1 n small misignition from the carburettor(have mom dismantled the air filter box so I can get better) So far none of my measures have caused a change in the condition, no change. Machine rotates, but does not jump on . Maybe one of you will think of something, I would like to drive again this year ^^! Thanks already!
