I have a 2012 400, on the way home from work I made a left hand turn and the engine just quit. I coasted to the side of the road and my dash panel was blank. I then turned the key off then back on and everything worked ok. Has this happened to anyone? I finished the ride home with no problems. I had thought that maybe I had hit a bump and the kick stand had bounced and shut it off I then tried it on the center stand and the engine would would die but then restart when put back up quickly. I then checked the battery connections and they were ok. I hope it is just a fluke. Thanks I enjoy this forum and read it daily.

Sure you didn't accidentally hit the kill switch. I don't think a complete electrical like that would be caused by the kickstand. I had a R6 that used to do that and it ended up being the rectifier.

no because if I had hit the kill switch it would not have started back up with out turning it back on. unless I just bumped it. I will try it again tomorrow and see what happens. Thanks for the suggestion, never have hit it before but you know there is a first time for everything.

It happens, it will happen again. I have 7600 miles on my k7 and it happened 3 or 4 times. Last time was just after a left turn.

There are 3 switches which will "kill" the engine......!! Not sure about the dash display...(??) 1) side stand switch 2) lean angle switch so if bike tips over - it will shut down! 3) kill switch.

I disabled the side stand switch with a nylon wire tie and hot glue - so now I can start the bike on the side stand..!!

It as happend to mine on 2 or 3 occasions but not for a long time,
when new the engine is tight and one missed beat at low speed and
it can stop as miles build it will very likely stop doing it and the
tick over will be smoother most single cylinder engines have a
tendency to do the same.

It happened to me on my 08 400 1 time, after coming to a stop I found that I had accidentally bumped the ignition key just enough to shut the bike down, the key was halfway between off and on.

What Ralph said.. yes.. I used to have a single cylinder 500CC Piaggio and it did that a few times...This sounds like the same thing.. FWIW.. PIaggio came up with a re map for the ECU that supposedly fixed it.. Maybe something similar from Suzuki?

It's not reassuring, but my 2008 did the same thing. It had about 400 miles on it when I bought it and did it a couple of times.

Totally forgot about it. I remember turning off the key, turning it back on, touching the rear brake and restarting it while rolling down the street.

Not sure what fixed it, which is unsettling, but I did take it in for the rectifier recall. Maybe they tightened the battery terminals. Maybe it simply got more miles. Maybe it was the rectifier.

I thought it might be a deal breaker, but it resolved itself. Fortunately, didn't get many opportunities to hone my restart on the roll skills.

It doesn't make sense, the dash doesn't go blank when the kill switch is in the off direction nor does it go blank when it just plain stalls.

Thank you all for the information, I guess I just need to deal with it and if it happens again I will take more time in checking it out. Today it ran fine and made the same turn and hit the same bumps with no problems, Keith you are right I checked out shutting it down with the kill switch and the stand the dash still worked. I did check all main power from the battery to fuse panel all seemed good. I don't think I will spend a lot of time chasing a burgi ghost.
Thanks again for all the tips.

Just one thing. When the bike is new this can happen as the guys are saying. It may be down to the engine being tight. But...one other thing people have noticed is this. At start up you must wait for the ECU to 'boot up' by allowing the bikes dials to finish their sweep to maximum and back before you push the starter button. Otherwise the bike loads a basic set of default running values which will not allow the bike to run at peak efficiency. This will encourage the bike to stall at idle or very low revs. Many have found this due to not knowing you must wait just a few seconds before pushing the starter button. Maybe you haven't always waited for the boot up to finish? Either way, since I started waiting for boot up, mine has never done it again and there are many others on here who have found the same. The only slight caveat is your screen is going blank! I'm not aware of that ever happening to mine. You may have a loose or faulty 'tilt' switch if waiting for boot doesn't cure it. Good luck.

I know you checked the power fro the battery but did you check the battery terminals were tight
they seem to have a habit of coming loose.

Thanks Ralph, I checked the battery terminals and the connections at the fuse panel. I will just live with it and hope it will not happen again. I am planning to ride it to southern Illinois in june. I need to find a seat cushion and a throttle control for the long trip. I have a sena sh 10 coming for the helmet. never have done a long trip on the scoot so any help would be great.

A simple O ring on the gap between the throttle and weight will hold it open and
you can roll it out as you approach towns to make the action lighter.

My 2011 did it once or twice when I was a noob, I had about forgotten about it.

What Quantum Mechanic said is key. Let the machine boot up and make sure the FI light goes off before cranking the bike. This is true of many cars also, I have had a few Fords with FI start poorly if not cranked properly, you have to allow it to perform the system check before cranking. Rare but it does happen.

These scooters get better and better as the miles add up. Hope you have miles of smiles.

Not a clue on the size I just call in at the local parts place and they let me try
a few till I find the one I want, but get a few as some seem to be affected by the sun
not that we get much of that in the UK
