Well not very helpfull pics but..... I have also got a HD. Never had any issue with it. This stall thing happend at least one other time I can remember. I was coming to a sign downshifting and applying the brakes apropriatly. The ECU suggestion makes sense.

I had the tank replaced do to warping by the way.

i think i see a pattern here.

are you relying on engine braking to help slow down the bike? if so, stop. if not, quit downshifting until you're stopped.

You're saying that to stop you pull in the clutch, apply brakes, come to a halt and then click down a bunch of gears? Guess I've been doing it wrong all these years. It's fun to down shift and slow the bike with the engine, especially with clutchless down shifts.

no, that's not how i do it.

while it may be "fun," it's certainly not necessary and it add's complexity to situation where simplicity may resolve the issue entirely.

fwiw, even when i downshift heading for a stop, i'm pretty sure i don't shift down into first unless i've stopped.

I was not leaning over much and probably in second going into first when she cut out.


and even if it was a stoplight vs a stop sign, i'm pretty sure his m1100 would pull away just fine in 2nd gear should the light change before he got fully stopped.

You should downshift and be in the correct gear prior to the corner and then throttle smoothly through the corner
even up to this stop you throttle and slowly bring the bike out of the lean then hit the brakes and clutch as you come to a stop

Shouldn't be braking with the bike leaned
shouldn't be downshifting in a corner

My old VTR1000 used to stall sometimes at slow speed. I almost crashed it once or twice but then I got used to the unexpected stall. These were always parking lot, stop sign, driveway type events. Is this happening to you at speeds faster than 4 MPH?

Oh BTW the VTR had carbs and it was a sticking slide, intake pulse issue. The throttle slides would bounce up and down a bit with each cycle of the engine and once in a while one of them would stick open a bit and stall the engine at or near idle.

It was kind of neat to watch with the airbox lid off. I don't recall my 750 doing that.

The down shift to first was at a slow speed and was not a big issue. As with my cars, and other vehicles (all of which have been manual) I don't typically shift into first until stopped. Regardless, the fact that the everything on the bike shut off momentarely is my major concern and troubleshooting my ultimate goal. Again, thanks for everyones help.  :D

Everything?

What about a bad common ground. Like at the battery.
Check your cables, it could be as simple as that.

adduncan101

Yep, everything. I will check the cables and other potential shorts. Good thinking.

  My 1100s stalled three or four times always on downshifts. Dealer could never replicate my problem. The bike was always at temp when this happened. My thought was it was running to lean in the closed loop portion of the map. I also had a starting issue. Bike would crank and crank and just not even try to start.

  I flashed my ecu and got rid of the o2 sensors and never had either problem again. Regardless of your riding stile the bike shouldn't stall when you pull in the clutch.

But it seems we overlooked his problem of every thing on the bike goes dark and shuts off. This is more than an ECU/stall problem.

LOL exactly. Engine braking has a practical purpose. If your bike is tuned properly it shouldn't stall on a downshift. It's all about the tune. A great many problems are solved with a proper tune.
The only trouble is, you have to solve a great may problems to achieve a proper tune!

EVERYTHING? Do you mean the dash went blank and then came back on with the start-up display? (I assume that display is similar on the M11 as it is on the M696).

Like does it say MONSTER 1100 or something like that when you first turn the key on, before it shows mileage or other data?

If it cycled like that, then yes it sounds like a main ground/power cable.

If it DIDN'T CYCLE (and normally does) then "everything" didn't shut off.

Yes kev m. lost the dash, everything (couldn't see the head or tail lights though)
It went lifeless. On top of that, as i stated in the begining the bike is only a couple months old and has  just over 3500 miles. Next thing I knew the engine fired up and the dash came back. I was for only a second but it was very noticable.

has there been any work on the bike at all? any aftermarket parts installed etc?
