Hello I have e ninja 08 250 and in the morning when is a little cold, I used the ckoke but the iding doen't go up.What i should do ?

Hello,

here's the link to the parts purshase for the blender you got:


Ninja Master Prep Pro System

you need to see if you have a spark at your plugs...this is your first step

Its seems natural. because when your starting cold the engine is not at the normal operating temperature. So when the engine heats up the idle goes up that means it reached the Normal operating temp.

Well, yes and no, It would depend on the outside temperature, If you live in the desert, it would be perfect. But if you live up north, not so perfect. It would never crank over on a cold morning. Oil is like little tiny ball bearings, the heavier the oil, the bigger the ball bearings, Multi viscosity covers 2 weights, when it is cold in the morning it is thin, 10 w, when it heats up after running, it gets thick, 40w. 10w40 would be a good weight for a small engine, heavy enough when hot, thin enough when cold. Some people use straight 30 weight year round, but it is hot down here in Florida, I use 10w40 in all my cars and trucks. Hope this helps.

How to use your choke correctly. The choke is only to be used for starting a cold engine. If it is a lever, usually you pull it up for on , and push it down for off. look for some type off arrow, or up & down. To start your cold engine, turn on fuel tap, give full choke, turn key on and press starter or kick start, it is very important that you do not use the throttle while starting with the choke, just turn the key on, and press the starter with full ckoke, and no throttle. Once the bike fires and starts, turn down the choke a little and find a idle, after a few minits, you can turn off the choke and ride off. The use off the choke is only for starting a cold engine.

your carbs need cleaning your fuel pickup tube for you cold start is blocked.

You could have a blocked main jet .When starting from cold your engine runs on an idle jet & choke .with very little air .When engine is warm ,there is no need for choke .and your main jet will supply your engines fuel & air ,however if the jet is blocked or there is no air supply like a dirty air cleaner unit .then there is a good chance thats your problem .One quick way of checking this is to try and start without choke and see if your plugs are wet .Then whle plugs are out test the spark by placing them on the engine .and turning the engine over .

so i drove my bike sputtering to school and notice that there werent problems with the fuel system cause i heard the engine drowning in the fuel cause the ignition system couldnt explode it by a to weak spark from the spark plugs, so i only had to change the spark plugs and everything was good as normal

sorry if my story writings look a bit weird, cause i dont speak or write english where i live

adjust the slack in the brakes as too tight can make the brakes ht & expand thus engage slightly!
