    Cutting out

    My bike randomly cuts out mainly when pulling up at junctions. It starts again easily when warm but a bit of a pain when cold(it starts ok cold if I open the throttle slightly) and it cut out on a long downhill. I have fitted a new stepper, plugs, balanced throttle bodies and set tick over. Any other ideas please

    I'm pretty sure that's a mapping issue .
    It's well documented on here somewhere Glynn.
    I'm sure it was also linked to a stepper issue . I know you've changed yours but it may need setting on a gadget

    It looks like the mixture at tickover is automatically adjusted by the ecu as it is spot on at virtually lambda 1 or do you have to remove the lambda and set manually. Good info is hard to get and the manual is a bit pants.

    Ahh .. In that case have a go at increasing or decreasing the global O2 figures maybe that'll help.
    It's hard to know what works best for your bike , trial and error stuff

    Nell idles better a little rich, around 12:1, and is less prone to stalling as you have described.
    Easy adjustment with TuneECU.

    Just make sure that the stepper is moving freely first. It won't idle properly if the stepper is sticky.
