Greetings to all members!
Maybe someone could help me with advice over this trouble?
For over two months I have a problem with starting my 1989 K 100 LT. My buddy who helps me with maintaining the bike has tried everything - but the same problem repeats: the bike won't start, because too much fuel is coming to the cylinders, flooding them. When we take out the spark plugs, they are black and wet from gasoline.
We first tried with checking and cleaning the injectors - didn't help. A friend from Croatia, who's a magician for BMWs, and who installed a new pressure regulator on my bike few months ago (so THAT can't be the cause) sent me all possible spare parts that could have gone wrong - volume air flow sensor, fuel injection and ignition control units. We changed them one by one, in this order, and the problem still keeps repeating. For one day bike runs normally, but next morning it won't start
Each time I have to take out the spark plugs, clean them, take out fuel pump fuse and press the starter button in order to get rid of the excess fuel from the cylinders - only then bike starts and works normally. There IS a bit too much smoke coming out from exhaust, and when I stop at the traffic light one can smell the gasoline, so it looks the fuel/air mixture is too rich anyway.
Cheers,
Tarik
