Idle is set to 1550 rpm not adjustable and not needed I believe
I think you should clean stepper motor end and passage with soft wire brush and cotton wool
What is the issue? I recently had to replace my stepper motor on my bike and in other bikes I’ve done several MAP sensors
Clean n scrub the stepper passage and end of stepper and it should show open about 45 steps if I remember correctly
45-55 steps
I’ll check up on that figure
The system is largely the same as many Chinese decent brand bikes and I’ve worked with Benelli and Zongshen Jailing also
