This is a common issue with the 250s. Partly because it is one of the last carbourated bikes. With all cold starts on the 250, it needs to be choked. If, after it warms up, it still wont idle, then it may be that the low speed jets are clogged. To clean these, you need to take out the carbs, remove the bowls and unscrew the jets. Please refer to faq.ninja250.org for carb cleaning detailed instructions.
Hi My 500r has a knurled knob that can be accessed from the left side at the rear of the carbs. Clockwise increases idle rpm. Ride Safe Roger M.
I believe its up, which ever one makes it idle faster
That vehicle is throttle body fuel injected, there is no choke or idle adjustments. You have other issues such as a large vacuum leak causing your idle problem.
No, only use the choke until the bike can idle without it
the choke is on
you choke may be on
there should be an idle adjustment on the right side of it
Possibilities are - stale fuel, how old is it? Blocked main jet or stuck needle jet. On choke, there is a little fuel which bypasses the main and idle jets, this allows it to idle with very little air. When you give it throttle, it uses all the fuel and air this bypass and idle jet can provide very quickly, and then starves for fuel as the revs increase. Basically the carby I would say needs a very good clean out, including all the jets.
well it depends on whatcarberator you have on it if yours have the choke on the side that you pull up then you idle it by turning the choke after you pull it up if your choke pulls out from the side then look on the right side of the carb and there will be a screw on the right side turn it too the right to get it to idle hope i helped
