The bike has had a consistant idle and was a pleasure at stop lights. yesterday the idle falters after a while and then the engine cuts. I have checked for faults on diagnostic and all is clear. I find not leaks on the vacuum piping and bike starts well. The battery charges at 12,5V.
the bike drives great in motion and throttle response is good.

I just need to figure out the reason for this change in idle.

Will check the stator output and voltage regulator tonight.

any advice will be appreciated to help save me effort and time.

Thanks
