bike stalled approaching stop sign, almost crashed!

[adduncan101]

I feel like I have heard about this before. I was approaching a stop sign last night. As the road turned and i applied the breaks and down shifted the engine stalled and the rear wheel locked up. I managed not to shit myself or crash the bike. Its a 2010 1100 s. Any thoughts?

Please let me know if anyone has a similar experiance or knows of a potential cause. I was shaken up a bit and I don't want this happening at high speeds in a turn. The bike was leaning a little, maybe it has to do with a bank sensor? The replacement gas tank had also been installed earlier that day. She only has 3500 miles.

Just out of curiosity, how fast were you going, what gear were you in, were you applying the rear brake at the time, and....not to offend you....how long have you been riding motorcycles?

I've never had any issues with a rear wheel locking up when an engine stalls while going down the road. At just about any speed over 5 mph, the engine will keep turning with the clutch engaged, even if the engine is off. My wife likes to play "Killswitch" where she sneaks up on you while going down the road and hit your kill switch when you aren't expecting it. Usually, even as slow speeds, I pull the clutch in, turn the killswitch to "on", and just bump start the engine while going down the road. Even when something went wrong with the bike, such as bad regulator and running out of juice, broken negative battery cable, carb issue, and even a simply cold-engine backfire killing the engine when taking off too soon without letting it warm up enough, I have never run into the problem you describe. The only time I've heard of a rear wheel locking up is when the engine, tranny, wheel bearing, or chain becomes trash and finds some way to lock up the engine/rear wheel.

HEY !!!

We play killswitch all the time..

- Maybe some more riding experience is in order here... just a thought ( not meant to be a bash)

I've had the 696 die on me when approaching the first or second stop sign down the street from my house once or twice. Each time on a cold start, shortly after shutting the fast idle/enrichener lever back to the normal position.

I've assumed that so far in my case it was just a normal low idle cold stall.

Never been a problem, always pulled the clutch in right away (perhaps instinctively).

If you were downshifting into too low of a gear you will get that feel of a lockup, but it's just the motor is turning at a different speed than you should be at for the speed you are going. that's why many of the newer bikes have the semi-slipper. otherwise you would get rear wheel chatter which would have probably freaked you out if you never experienced it.

also, as far as a cold motor... yes, I've had the same situation. Bike not idling at 1200rpm and warm.. it will stall if I pull in the clutch and not rev it.

BUT I'm curious about your replacement gas tank issue? what happened that they replaced it?

oh. and what the hell is a bank sensor?

I've read where some bikes have a sensor so that if the bike falls over, it automatically kills the engine - such as in the event of a crash. I don't know of any bikes that actually have one, though. None of my bikes have one.

[Raux]

so let me get this straight.

he was in a turn with a decent about of lean and downshifting?

Maybe this should be in the riding techniques section instead of the general section

- Seriously the Monsters have no such items. Dump it on it's side and it'll keep running

yep I know that

The bike likely doesn't have to be cold to stall. My 848 would stall at random at intersections, regardless of temp. I've heard some complain of the newer Monsters doing it as well. It sucks. The fix for my 848 was a new ecu map (race ecu with Termi package).

My guess is the rear wheel didn't fully lock, but may have felt as though it did due to the low speed.

Anyway, shouldn't be a huge issue at speed, so i wouldn't worry about it. They aren't known for stalling at speed, but if a bike stalls at speed just release the clutch and it'll re-start. If it's in a false neutral just bang it up a gear and it'll re-start. No biggie. I've had it happen on my race bike a few times (before I raised the idle) when I wouldn't hit the lever right and I'd get a false neutral. The cause is a completely different issue obviously...but a stall at speed is a stall at speed.

Harleys have had these for some time - it's also part of the self-cancelling turn signal circuit (if the sensor registers the forces of a lean it shuts off the signals after it senses the bike come back upright).

I don't know of any other manufacturers that are using them though...

[Raux]

I know what Harley has them.

Cause they rarely wear gear, so they aren't expecting their riders to get up after a wreck.

Amusing stereotype and true too often, but spend some time around actual Harley  RIDERS and you'll be surprised how many wear gear these days. But then again, I've been riding Harleys (and wearing Aerostich on em) for going on 2 decades...

[Raux]

eh just a joke

No offense taken. I have been riding on and off since I was 12 maybe (dirt bikes) and Im 31 now. I will say I can always be better and do, like anyone, make mistakes. This was a problem probably resulting from a couple things. I may have reacted poorly when the tack went blank and the motor stopped for the brief moment. I will also try to post a pic or two of the stop sign, the curve in the road, and the tire. I was not leaning over much and probably in second going into first when she cut out.
