2011 Ninja 650R Difficult Cold Starts

Hi everyone,

I've just bought a 2011 Ninja 650R with 3300km on it. It's a great bike but one thing bugs me, cold starts first thing in the morning it seems to take 2-3 try's to start the bike. On the first and sometimes second attempt it starts, runs low rpm for a second and stalls. Then fires right up on the next attempt. It starts perfectly once warmed.

I called the dealer and they said that it's pretty normal? Wouldn't have thought so..

I've read that on the older models some people had success by turning the fast idle screw on the throttle cam, does anyone know if this applies to my model as well? Or any other ideas?

Just to update the weather is a bit warmer this morning and it started on the first attempt. Seems to be lower air temp specific.

I would be looking at your battery for starters. Perhaps because of the cooler temps it hasn't enough grunt to fire up first go. Do you have a trickle charger?
Not sure about the fast idle screw.

It's cranking over strongly, no problems there. It's just that it dies after a few seconds the first time.

I do have a charger so I could try that anyway.

When it does start on the colder days, what speed/revs does it idle at?

When the weather is cold, give it some gas when starting it.


Don't rev it to much, just an instant, helping 2k rpm turn of the throttle when you feel the engine bursting into life and then let it settle to the correct idle speed.

I had similar issues last winter with my bike, meaning if it didn't catch first time, sometimes I couldn't start it and had to hook up the Optimiate for the day.

I've just fitted a Shido Lithium battery to my Zsx. Apart from the weight saving, the battery has superior cranking power, so starts the bike first time, every time.

Time will tell as the real cold weather has only just begun here in the UK, but I'm very happy for now!

It started fairly quickly and idled at 800-1000rpm for a second or two before stalling. On the second or third try it started up at 1100 then initiates fast idle between 1600-2000rpm as it should.

The bike sat around for a year or two before I bought it and since getting through a tank or two of fuel the starting has been fine so I wonder if the old fuel was contributing to the problem. Then again the weather is also warming up now. I guess I'll have to wait for a cold morning to confirm.

Thanks I'll give it a shot if it happens again.

That sounds like a great upgrade but as mentioned above it has no problems cranking. Thanks for the link though.

I wouldn't worry about it. My '13 650 does the same thing come winter time. It starts fine, after a bit the revs get really low and the bike seems to almost choke up - give it a tiny bit of throttle for a few seconds and the revs should go back to normal. It can also help in the winter to tune your idle speed a bit higher as well, just remember to adjust it down again come warmer weather!
