Dear All,

my engine will not start again and the revolution counter will react without pushing the start button.

engine will get gas
sparks are new
starter is new
battery is new
all plugs are checked 

My guess is the hall sensor or the watertemperature sensor

It would be very helpful if you could give me your ideas.

thanks a lot

Markus

Watertempsensor; it will start, but not good.
Hallsensors; both must be broken, don't think so.

Check the sidestandswitch and the clutchswitch, and check if the neutrallamp is on, and zero on the dash.
Good start, good luck


I just send you a personal message

What does this mean?

Have you tried pulling in the clutch when trying to start it?

After failing to start are the spark plugs wet or dry??
Regards Martin.

A faulty temperature sensor or connection can cause an over rich mixture and failure to start. 
Removing the fuel pump fuse #6 or disconnecting at the four pin connector will allow the engine to start on the residual fuel in the combustion chamber. You will need to work the throttle and as the engine starts to die insert the fuse or reconnect the pump. Having an offsider helps. If it does start and run it will be running rough and you'll have to work the throttle. You will now have to either clean the connector or test and replace the temperature sensor.

Hey folks,
Allright , The Problem is solved.
I checked The Hallsensor and it is damaged.

One of The magnetic ports gives no signal.

Many thanks for your ideas and help.

Best regards 

Markus

Good
And now ride
