Over the years I was trying to establish good idle speed (with out good result) and turned the adjusting trotle screw in every location.
I want to start with good air flow ratio and see if this will help.
If the idle speed is to small the engine shut off if idle speed is to high it will trigger the red ( engine symbol ) light at dash board.
At this moment the idle speed on my motorbike is in good range till the cooling fans switch on.
When cooling fans gets switch On the idle speed is slowly dropping down till engine shut off.
When I use hited grips the idle speed is also dropping down and engine shut off
If cooling fans or hited grips get switch off before engine shut off, idle speed will return to normal.
I am not sure if this problem is to do with air/ petrol ratio or this problem is do to some electric faults.
Is the any sensor wich I should change?
Recently I have made upgrade to alternator on my bike from originall one 200W to Zongshen 300W and new regulator.
Valves has been set recently with full service change
- air filter
- fuel filter
- Oil filter
- oil
- new Map sensor
- spark plug
- yuasa battery one year old charge up regular
On old alternator it was the same problem.
Any suggestions as this is very annoying problem
Thanks

First try this:
Reset ecu switch on off 5 times (heat pump prime) wait 15 seconds then switch on, this erases old learnt data and sets TPS correctly and should show 0% value on live data under 1% is ok
Check full throttle gets to 100%
Ignore the other throttle value if less then 5.
Second clean throttle body and adjust butterfly stopper so it’s fully closed and clean stepper passage and stepper motor nose - idle you should get 2.3Ms injector duration and oxygen sensor cycling up n down, stepper around 45/50 steps at around 1500-1600rpm
Reset ecu once you played with throttle body.
Any more data details you can show?
If you’re in the UK Honley might have a spare sensor as I sold some to them or I can supply.
Kinda need to see info rather then a description
Hope this helps you to see n learn a bit more
