holy crap, I stall on downshifts

[teddy037.3]

seems to only happen at lower speeds (1st, 2nd gear), today it's happened like 5 times... clutch pulled in, blipping throttle, the same as I've always ridden.  then when trying to restart it's like the starter doesn't want to turn it over unless I mash the throttle while holding start.  help please! throttle? tb synch? TPS?

so, to be clear: it goes clutch in --> press shift lever (to 2nd, or 1st) --> stall

2011 hym796, all stock, if that helps any.

Does it try to turn over?  You hear the clicking noise each time you hit the start button?

What about the choke?

I have the same issue with my SuperSport 900ie (not the downshift though), but it's hard to start unless I have the full choke and blip the throttle a bit.

[teddy037.3]

it'll just barely start up, then stall.

no choke/fast idle on the bike

I think with the 1100 the TPS resets each time you start the bike (no throttle input otherwise buggers up the calibration) but to do a hard reset you cycle key on start welcome screen key off 3 times. If anyone knows whether the 796 does the same that would be a quick check to start.

yeah, it works the same way (no fiddling during the.. boot? of the dash). not sure on the hard reset thing, but I guess it's worth a shot

How many miles?
Valve job performed?
Belts replaced?
How long has it been stopped?

This happened to a customer's M796 same year . . . if your idle is not 1250RPM +/- 50 then your stepper motor can be faulty; if it's too much for you, to reach the battery and do a reset, then take it to the dealer or a tech with a diag tool . . .

It's a Continental/Siemens[VDO] so, try this procedure, if you still have the issues, then take it to dealer

5300 miles, no service outside of the 600.  bike sat for several long stretches.  I rode on it last week and it was fine the whole way, all this started today.

i'll try the 3xstart thing and get back to y'all

OK

[Scoober1103]

I may be confusing posts but I think some on the forum with a m796 had a similar issue! The stepper motor rings a bell! Could be entirely wrong mind you!

did the reset thing, bike started, idle looked ok. turned it off, went inside to gear up for a shakedown, now the bike will just barely start, sputter, and die.

tried in gear, in N, kickstand up, nothing.

perform the reset again, keep your gear ON . .. once it starts, wait a minute or two, change dash to voltage while listening for idle RPM . . . voltage should be around 12.8V~13.2V, if less, there might lay your issue . . .

[teddy037.3]

reset, still nothing. I can still start it by mashing on the throttle, then idle holds steady at ~1200, BAT shows 13.5

[DarkMonster620]

so, will only start IF you wack open the throttle?

don't have access to manual from home . . . do you have spark plug socket? take them out and describe colour, please

[teddy037.3]

yeah, but the stupid thing was it started right up fine this morning, then fine when I left to the dr., then fine when I left the dr.  all the stalling was happening in between and now now.

will look for plug tool
