Mine is doing the same thing. Would also like to know.
2008 690 SMC Starting issues
Hi everyone, im currently having some issues with my 690 when starting it up.
No matter if the engine is hot or cold, it takes 3-4 attempts on the starter to fire it up.
Decompression spring has been switched a couple of years back and according to previous owner everything was fine for awhile after that.
It has never stalled or anything once its up and going, however its abit jerky and groggy on the lower end of rpm's.
fuel filter/injector issues?
heres a vid of a startup:

Fuel pump
I have an 08 SM610 (yes I know this is from the pre ktm era of huskys) but many parts are still shared. I had/have a similar sounding issue at starting. Granted mine only take two tries and usually only when cold, but when it was really bad (worse than your vid) a new fuel pump fixed it. There is a company in CA (which I cant remember the name of) that makes a better version of the stock pump that fits in the stock pumps place. Also I have been told additional fuel filtration and using "better" gas will help. (for the record I only put 93+ in my bike, but some people say I should only run race fuel...)
Hope that helps. The fuel pump did really improve my starting and now I find priming the pump by cycling the kill switch before going for the ignition button helps too.

the 690 doesn't like low voltage batteries on their way out either. it looks/sounds like its engine management is fighting somethingHi everyone, im currently having some issues with my 690 when starting it up.

Things that it fights:
fuel: old gas? just have to ask
spark plug? bikes don't idle well with a old plug
Battery: low charge, its age, my '10 690 doesn't like old batteries with less than ~12.8V resting
fuel filter: might need a new filter, theres something in the fuel system that breaks down that produces this grey sludge, meaning that your filter will clog, your injector will clog and maybe your pump will need replacing (CA Cycleworks makes a good kit with all the hoses needed - I've run mine for a couple of years now; no issues) your injector should be taken to a local race shop for a proper cleaning
rocker arms: have you recently replaced them? you don't want their bearings to go. this is a consumable part, when the bearings are off the timing is thrown off so the engine mgt fights that
valve adjust? have you done one recently?
pump: not likely yet as pumps will start to fail when they get hot, then will work when the bike cools again. btw keep your tank full to keep it cold.
CA Cycleworks makes that pump replacement kit.
Update:
After having the bike stored for 12 days without driving i took it for a spin yesterday.
Fired up instantly after pressing the starter just once.
But then i parked it for a couple of hours and started it up again it was back to the normal 3-4 presses of the starter.

The issue seems to get better by the day, lately it has been starting right away without any issues. Only differences i could think off is an oil and filter change and switching to a higher octane fuel (98RON)
Pretty low RPM when it does fire. Are you giving it throttle to bring the RPM up to 2k or is the computer doing that. Add some throttle body checks to your list - specifically whatever minimum air is called for this bike. I have a vortex so my idle speed is manual adjust, your bike sounds like mine when I try to start it without bumping up the idle sometimes though that is definately heat - dependant.
No im not doing anything besides starting it up in the video.Pretty low RPM when it does fire. Are you giving it throttle to bring the RPM up to 2k or is the computer doing that.

So basically if i let the bike stay still for more then 1 day, it always starts up on the first attempt.
However if the bike's already been ridden within the same day or just a few hours between it's back to 3-5 attempts to start it up.

I have the same issue, in the morning it start perfect. After the working day I need 3 or 4 attemps. Did you solve the issue?So basically if i let the bike stay still for more then 1 day, it always starts up on the first attempt.

Checked valve clearance.
Checked bougie
Checked injector
Everything is ok.
I'm suspecting the fuel dongle, maybe swap back the o2 sensor.
