Throttle problem

[pepston]

Does anyone know the reason why at a particular point in opening the throttle, usually about half way, the motor cuts out even when pedalling but then if opened fully after a few seconds the motor kicks in again? I`m new to this and haven`t much experience. Could it be an electrical problem? Appreciate any feedback.
Regards, Steve.

Ain't got a clue, Steve.

It does a similar thing on my Wisper 905, and has since it was new 4 years ago. Usually with me it's when I first use the bike, and it's on pedalling. Just for a second, the power goes, and then it's back.

I've learnt to ignore it!
