Exclamation 2009 Ninja 250R dies after adding throttle and pulling in clutch!

I have a 2009 250R and it is hard to ride it without stalling in cool weather and even more so in cold weather. I usually let the bike warm for 5 minutes or so with the choke fully engaged. The idle RPM averages 4000-5000. Then i disengage the choke and it falls to just below 1000.

After this started happening, I would let it warm for close to 7 minutes with the choke fully engaged in cold AND warm weather conditions. I disengage the choke and it again falls slightly below 1000 RPM. Afterward, I'll try to get going, and as soon as i give throttle with the clutch pulled in, the RPM falls off and the bike stalls.

If I do manage to get the bike running, there are times when i ride a distance, come to a light after driving a couple blocks and stop. As soon as i stop, there are times when the bike stalls out just seconds later after trying to ride away. BUT, the bike runs fine after driving it about a mile and a half.

I do not know whats wrong or what I can do to stop this? Help please!Thanks.

adjust the idle screw. when you pull in the clutch, the rpm should be around 1300rpm. Also, you shouldn't let the bike sit there for it to warm up. Idle it for about 60 seconds and ride off with the choke on. It'll warm up the engine faster than letting it sit there

I recommend you spend some time and read your owner's manual from cover to cover.

How do I raise the idle speed with that little knob? If I turn it clockwise towards the front of the bike, will that raise the idle speed?

+1, this is motorcycling my friend...don't just expect to learn everything off of internet forums, some things you just have to fiddle with and do for yourself to get to know your bike better.

Gents,

I am having similar issues. After winter passed I started the bike up (after a few attempts) and it didn't need too much warming up. It hit the idle at ~1500RPM without needing too much choke. Nice and solid idle RPM. Took it for a spin and everything responded nicely.

My Winterizing:
Drained carbs
Filled tank
Stored in garage

It is a 2010 Ninja 250 which was barely driven last year due to an accident early on. We're talking about a brand new bike. Anyway, I just tried to start it up today (2 weeks after I first took it out) and it was not easy. It took me maybe 5 tries and 10 minutes of playing with the choke and idle knob to finally have it warm enough with proper idles. I think I won't be able to start it next time. Check out these videos:

This video shows me closing the choke. Whenever I did this the bike would die. It managed to stay on this time so i tweaked the idle knob again and it died: http://www.youtube.com/watch?v=ewZa185y9lA

This second video shows the choke being closed and the revs increasing. After trying to bring them down with the idle knob, I gave up and killed the engine: http://www.youtube.com/watch?v=W5s7J8pdUsA

I am going to try and fill it with fresh gas. It only has 470 KM. Any thoughts? Also, my choke lever doesn't feel tight when i open it, it feels looser as I open it. Not sure if maybe the choke is not working properly. I understand it's not easy to troubleshoot these things online, but any ideas would be appreciated. I will post back when I change the fuel.

fresh fuel in the tank? if not, refill w/ fresh fuel and add some seafoam. You might just get lucky and that will possibly fix the problem.

I'd try all the home remedies before i would take it to a dealer.

Well, I figured out a trick, but I thought I'd get a technical opinion too. When I press the starter button, I also blip the throttle so it turns over. If I don't use the throttle, it won't even start. So far it's been working like a charm.
