Question about 2003 kawasaki KX 250

2 Answers

I recently inherited a KSF250. It does not run and I know little about motorcycles or atv's. I don't think it's getting spark. My real question is how do I find out what year it is? I have the serial number--JKA8FMA1XJB510877. Any suggestions would be appreciated.

    Thanks for you response. I have learned thru Kawasaki that this one is a 1988 model. I have already tried grounding the spark plug as you suggested with no luck. It is kinda difficult because this model does not have electric start. I'm wondering if it could be the plug/coil wire. Can these be tested? Any other suggestions would be welcome.

Look for a decal or metal plate attached to the pipe in front of the gas tank. Manufacturers often put year of manufacture there. Check spark by pulling the spark plug and grounding the plug to the engine while trying to start the engine. Look for spark as the engine turns over. The plug can be grounded to the engine by simply touching the threads of the plug to the metal cylinder.

    Have your best buddy kick the starter while you hold one hand on the cylinder and one hand on the end of the spark plug wire. Yea, I am serious. It won't kill you to get a moment of shock and will eliminate the question of spark really quick.

    Did you use a used plug or a new plug when checking for spark? A used plug can have carbon buildup on the porcelain center insulator and the electricity can go to ground thru the carbon > no spark. No electric starter and only one person does make it hard to check for spark. Get a neigbhor, friend, wife, girlfriend, passerby on the street or best enemy to kick the bike over while you look for spark. Be sure the plug has good contact to ground.

    ....Again, IF in doubt as to spark, have someone else kick the starter while you hold one hand on the cylinder and one hand on the end of the spark plug wire. Yea, I am serious. It won't kill you to get a moment of shock and will eliminate the question of spark really quick...... Yes, coils and coil wires can be tested. But not all dealers have the ability.

Not getting fuel

Harley FI systems had a problem with the hoses in the tank getting holes in them, if pump is running but no fuel to injectors then this is where I'd start to look. My suggestion is to buy a repair manual from HD, they are about $50 and they are worth every penny you pay.

Need to know where the hoses from the carborator go on newly aquired honda 200x atv 1985 also the carborator was torn apart when i got it i think its back together right though

The hoses from the carb are a bowl vent hose (top one) and the one out the bottom is a bowl drain. They don't connect to anything, typically they run down in the frame behind the motor. Good luck!

My dirtbike sat in the garage for 4 years now it wont run right .

have you checked the reeds inside the induction side if they are corroded from sitting it will cause that problem, also check the spark plug, may just be a case of weak spark ,if still no good check the coila good way to test if it is a spark problem get a can of aerostart (wyns start ya bastard) and spary a little in carby, should start real easy. if so then spark is your problem. also just thinking check tat your exhaust has not collapsed inside itself or is blocked, that can cause no power too. hope i have been of some help.
