Title: k75 too much fuel
Post by: lysy40 on September 18, 2017, 12:08:07 PM



Hi, I have a problem with k75s dont start . Fuel leaks with the exhaust system. On the Polish forum bmw advised me to check the power supply injection leds.

Keep the battery charged up because a weak battery will not only fail to start the bike but also damage electrical relays when it is weak. What is the battery's resting voltage?

Several conditions could cause this.
There's more, of course. There's always more.  :yes

Yes new fuel, Spark plugs sparking. From forum bmw google translate  :dunno
[size=16px !important]Unplug all plugs from the injectors. Unscrew the wide plug from the driver - it is under the driver's seat. Touch one end of the ohmmeter to the 12 pin plug, and the other to the ground. How to sew - cable attached to the ground. How is it not the same procedure with the driver - as it will destroy the dropped driver. As it is going to be fine it is still an option that any injector is shorted to ground. Unplug the battery[/size][/font]

What are you trying to learn by doing this test?

Which system do you think has a short circuit—ignition or fuel injection?

Possible faulty temperature sensor or sensor connection. Remove the spark plug and let it air for 10-15 min and replace the spark plugs. Remove the fuel pump fuse no 6 Krafftstoppe  and start the bike the bike should run on the residual fuel you with have to manipulate the throttle. As the bike starts to die, replace the fuse it should run albeit roughly. It is better if you do this with two people one to start and work the throttle and one to ram home the fuse. if this works you will need to clean and check the sensor.
Regards Martin.
