Hi I have a 2009 Adventure, while slowing down for a roundabout today from approx 80mph down to 40 mph the bike cut out, it was then slow to start its never done this before and didnt do it all day, any clues??
Engine cutting out
- Thread starter albonet
- Start date
Do you blip the throttle on downshifts?
Bike slowing down
Had exactly the same thing happen on a 1150GS once coming up to a roundabout 2 weeks later it cut out again, it was a wire from the ignition barrel to the
next plug in the line it happens when the wiring loom is cable tied to tight to the frame and the wire eventual work hardens and brakes, worth a look ??

When engine revs are above the road speed the ECU cuts fuel to the injectors. Blip the throttle gently to increase revs then let it fall. The tacho needle will drop below normal tickover speed then the stepper motors catch and the revs pick up again.
If the any or all of spark plugs, coils, throttle balance and fueling are not right the revs can drop too far causing the engine to stall. Below a certain low low revs the ECU will just let the engine stop/stall.
A faulty coil can do this. I had the same symptoms for a while then it would sometimes missfire on one side. Take out the primary coils and do a resistance check. You will need long prods on the test meter. I eventually proved mine by checking exhaust pipe temperature, swapping coils to the other side and seeing if the cold side moved. For a long while the coils did seem to be ok but only a GS-911 would have spotted it sooner.

THanks for the info it gives me some thing to start looking at, thanks again boys.
I've always done this. never known why though. I just thought I was being cool. Then again, I should really have known better - all evidence pointing to the contrary.

I've posted up a similar problem I'm having and had intermittently for the past 2+ years. It's getting worse and now in BMW where they are removing my aftermarket parts and putting it abck to stock to see it that fixes it.
Here's the thread with a video I did.

Throttle blips to match the gearbox speeds on downshifts are a good idea. It should have zero negative effect on the engine fuelling.
