High idle issue
Hi everyone,
I just got a stock 2005 Ninja 250 with around 7,000 miles on it. It has a problem where it idles high (around 3000rpm) sometimes, and I'm wondering what you guys think the problem might be? Here is a video of the issue: https://youtu.be/-gNxZgNplfM

check the easy things first, the choke cable pinched, binding or somehow pulling the choke 'on'
also check for a vacuum leak in any of the emissions plumbing. I dunno if VC has draconian emissions laws like CA, but if you have all that jibber-jabber stuck on your bike, best check it out. my bike had a persistent wandering/high idle when i first got it running after cleaning the carbs. A couple good rips on the highway at 75 mph blew all the junk out and got things running smooth... the old 'italian tune up' |

High Idle thoughts
I just went through this on my 07. It turned out to be a choke slide screw that was to tight and binding, not letting the chock return spring do its job. At the handle bar the choke was off, at the other end of the cable the choke was still one because it could not slide back to the throttle/brake side of the bike.
SO before you go taking everything apart, get your finger down in there and check that there is no binding on the mechanism. My two cents. |

Now...now...
You need to have patience and think of finding the cause as a challenge. Check that the carb clamps are all tight and the carbs are seated correctly in the boots. Make sure you have adequate slack on the throttle cable. Check for a vacuum leak. Check that the slides rise and fall smoothly. The carbs may also need adjustment and syncing or a thorough cleaning. |

You need to double check things again.

I had the same problem in the past. Grabbed a bottle of starting fluid from Walmart and sprayed all 4 boots (2 from airbox to carb and 2 from carb to motor). Sure enough, one of the boots was leaking. Rpm changed immediately. Tried tightening the clamp, but that didn't help. Replaced boot and all was good again.

As you've inherited this bike as is, i'd surmise the PO whacked out the carb adjustments during his cleaning.
Did you actually remove them and eyeball the throttle plates? |

Whenever buying a used bike, it's always a good idea to go thru the bike meticulously, not only is it an excellent learning experience, but it's also an excellent piece of mind, and safety.

The STUPID store is out of the product I need to check for boot leaks. Edit: Never mind. It's missing below 2500 on one side. Last futzed with by Milsparro; July 6th, 2015 at 06:31 PM. |

Solved. First time in 14 months (and 9800 miles) it's idled. Carb cleaned again, freed a sticky piston in the idle enricher, checked for boot leaks with propane (none), did the valves (2 exhaust were way too tight) and wuddya know. It idles. Like a normal motorcycle. 3 turns out on the A/F screws, haven't tweaked, may not, it comes off throttle fine. I did all of the above after I got the bike, but I remember not taking the idle enricher apart last year, as at that point I didn't recognize it as a thing. So, uh, yah, make sure that piston isn't all varnished with gas too. |
