Throttle problem, advice please

[Gballs]

Hi Guys, I have a Yamaha MT09 ,2015. It has an electronic throttle, ie, ride bye wire.
Occasionally now , when I hit a bump in the road,the throttle cuts out. The engine warning light comes on but the engine still runs, only at idle. I stop and turn the key off ,start up again and all is well. Doesn’t happen very often, last day out was a 400k ride and it happened once. Bloody dangerous if it happened at the wrong time!
Think if I take it to a Yamaha shop I will be up for lots of dollars, and not much chance of a fix with such a random problem. Any ideas?
Cheers:angry2:

As jelly said. Should throw up a fault code via a Yamaha plug in.

A simple loose wire or connection ... be it an earth wire or the throttle wire itself.

All you need to do is find it.


How hard can it be to find ... :innocent:


Or ... you could pay money to someone that knows where to look ... :shifty:

And will probably come up with Throttle wire fault. Or similar.

Exact issue (and location) would be unlikely.

Get an OBD reader and cable.

My money is on a lose battery connection or side stand switch.

I'd be thinking more likely the kill switch. About where his right thumb parks.

I'd be thinking more likely the kill switch. About where his right thumb parks.If it was the kill switch bike wouldn't idle, it's likely the throttle wire but which part of it.

either one of the two ends or the middle would be my pick

Thanks for the input guys. Have checked the battery connections for tightness, and checked the side stand sensor.
All seems to be good. Guess it will be off to the Yamaha workshop if it happens again.
Cheers
