Good day. I have the following problem with my GSX600F (built in 1994): I bought the machine cheaply and in a way (I mean that a replacement engine was installed) and was still very satisfied with the machine until recently. It cost me a few weeks to get the machine on the front, but it looked quite good until the engine didn’t want to start. However, I also got this problem fixed. I always have the spark plugs a Then the big day before the tuv came. I threw myself on the machine and after 2min it came to the unfortunate slipper on my property… 16 meters slips, engine went off and it was amazingly all right. Except for a few smaller scratches on my side and a relatively taken side panel. However, the machine then did not want to start for the rest of the day… also the next one. One hears how the starter gives everything, but only 1-2 cylinders make up. TÜV therefore fails. A few days later I transferred the motorcycle to another garage with the help of a trailer. Also there the motorcycle did nothing. The next day I tried it again and voila, the engine ran. Although a little rough but otherwise as it should. The next day, however, everything was like after the fall… the starter yaws and one to two Cylinders try it every now and then but that’s it. I’ve taken out the spark plugs several times, emptied the carburetors vie Benzihnhahn and after some time again Verbaut however everything does not help. The battery was always full (acid battery). Does someone already have similar experiences or an idea what it might be about? After weeks of despair I really annoyed and refuse to go to the mechanic because I’m very motivated now what screws used eht. However, I am just reaching the limits of my still very limited abilities… I thank you already in the Vorras…
