Hi steve,
What rpm does your problem occur at ?
I haven't had time to read the manual yet ,as i have just returned from a
weekend
away. I will have a look into it over the next 2 days and see if i can find
anything to help you out .
This may be of interest , when i took my bike to the red line and beyond ,
it
cut out 2 cylinders to protect the engine and the EFI light started flashing
.
It only came on to all 4 cylinders when the engine reached 5000 rpm approx ,
may be your ECU thinks your bike is over reving .
Could point to your TPS miss reading , Hence IPS error due to pressure
change
caused by 2 cylinders going down .
