Pull back on the throttle to make sure the cylinder is getting gas. Also try hooking it up to a car battery via jumper cables see if that helps it turn over better. if so the battery is probably getting week and needs to be changed. And your carborator needs to be cleaned. Air filter needs to be cleaned weekly.

The bike will not shift into gear. The clutch has plenty of spring tension just will not engage

if the bike has been sitting for a while the clutch plates can stick together, you will still feel spring tension from the pressure plate. two ways to free it up.
with the engine stopped click it up into top gear, put the front wheel against a wall, pull in the clutch, and push on the kick start, or push start it in gear, pull in the clutch and vary the throttle .
Change the oil after the ride with good motorcycle engine oil.

Kick starter has no compression, will not shift

hi, will the shift lever shift up when the bike is being pushed along, is it stuck in neutral, if its in neutral then push it down make sure it goes into 1st gear then can u get someone to push u whilst holding the clutch in then release the clutch and see if you can jump start the bike that way.

when you push the kick start down is it turning the engine over properly and if so if the compression is really to low then the chances are the piston ring has broke and scored the side of the cylinder if this is the case then you need to get new piston and rings and a new cylinder.

The problem with moto x bikes is they are high power and work at really high temp so parts need changing more often the piston rings need changing every 25 to 35 hours of riding time you need to do this as they ware and brake if used any longer.

you also need to make sure you get the petrol and oil mixture spot on as if its not getting enough oil it will blow the piston and rings so you need to measure exactly the correct mixture.

these bike are expensive to maintain and need new parts on a regular basis so remember this the next time you get the bike running

there should be a little glass sort of casing by where the kick start sits while rinning and wait till it fills up but dont put to much in or you will have to pay out for a new engine haha stupid ideas anyway

How to test the engine coolant is curculating correctly ? as this is my first water cool bike.... cheers Phil...

you can start the bike up and leave it idling with the radiator cap off until the thermostat opens and see the water circulate thru the radiator once it is full and you see it circulating you can put the cap back on
do not open the radiator cap while the bike it hot

KLX 250 won't fire - new battery

-check the fuse right hand side below the fuel tank and seat, see if it is blown.
- Check to see if plug has spark, replace if necessary .
- Did you run the bike with a low battery before replacing it? could be that your stator is shot.
-Is bike trying to start but won't?

Klx 110 2006 stalls when choke is pushed in

i'd say the carb is gummed up especially the pilot jet (#16158) in this pic of the USA carb. may have to remove the carb & bowl and then remove the pilot jet (w/ flat head screw driver) and clean out the tiny holes.


the carb slide is installed backwards (turned 180 degrees). its #16025 in the pic. i've done this before on my daughter's XR70 and Z50. you'll know if its this when you move the choke lever, RPMs increase and decrease.

hope this worked for you and was fast enough.
