Stalling after a Stoppie...

...or even after coming to a stop from hard on the brakes.

After pulling up to the lights on the front wheel yesty, the big twin slowly stalled. Almost like it was starved of fuel.

It happened again today after a hard stop, this time with the back wheel firmly planted ground. When I notice the revs dropping a quick blip of the throttle seems to fire it back to life. This is all after a pretty high speed day on the bike.

Has anyone had this happen to them? It's a new one for me. My first thoughts are the fuel filter is partially blocked.

Thoughts?

This was happening to me a lot at one point. It went away when I tried to fix my other problems. Replaced: TPS, reg, battery, and installed a JEGS filter. Never figured out what was causing that issue. I used to think it was low gas/starvation.... but maybe it was bad tps settings also. not sure

How much fuel in the tank? When my fuel gets low it does that.

Sounds like fuel starvation, fuel gets thrown to the front of the tank under hard braking/stoppies, more prevalent on 05-06 bikes.

You can buy some inner tank foam which cures it a little as stops it being sploshed about.

Yeah, sounds like fuel starvation.
Don't do rolling stopped up to lights on a busy dual carriageway when running on reserve. Cos you'll look a right dick when the bike cuts out and then won't restart, the lights go green and two lanes of traffic have to wait while you sheepishly push your bike over onto the pavement!

Interesting. Sounds fair except for the fact that it's only just started after nearly 40k

I can make mine do it consistently but only in one place.

If I brake hard on the run down to a roundabout on the outskirts of my most local town it will stop the motor every time as long as the following conditions are met.

I must have just started the bike from cold at my home about 3 - 4 miles from the roundabout, the tank can't be more than half full and the braking must be properly hard like on a track day.

The run to the roundabout is downhill so if braking hard, downhill with the engine still warming up and a half empty tank it stops every time. In any and all other conditions I have encountered you can brake till your eyes bleed and the motor remains indifferent and unaffected. Curious...

For what it's worth I think it's a fuel issue and not one that bothered me as the conditions needed to manifest it are rare and easily avoided.

Good luck with yours.

Could be any of the above but also disconnect the roll-over sensor and check that at some stage.

Roll over switch? Is this the switch that kills the motor in a lie down?

Fuel filters eh? Woulda thought this was done at the billion dollar 30k service. I'll check when i get home.

She's getting to that age I spose. The cougar kilometres as it were.

My bike has just 6K miles and did it when it had half that. Doesn't seem to be wear related although some people has suggested it's more common on earlier bikes. Mine is an 06 model.

Search BGC. Stalling after nose wheelies, hanging idle, etc, etc, etc....

I had them all 6 months into ownership. Dried and lubed BGC all electrical issues have been sorted...gong on 5 years now.

As others have stated, with 40K miles on the odo the fuel filter should be replaced.

For what it's worth once you've cleaned and protected all the connectors, ensured the filters aren't restricting fuel flow and ensured the roll - over switch is ok you are left with fuel surge.
I've had 3 SDs and they all suffered from cutting out under hard, prolonged, braking when there were low fuel loads.
The only thing that helps is to stuff the tank with fuel tank foam - this really reduces the problem.
