Question about 2004 kawasaki KLX 125

1 Answer

I have a 2008 Kawasaki klx 125 I just bought used which takes 20-30 kicks with the choke on to start and if it is cold outside even more. Then the choke has to stay on for a minute until the motor gets warm or it won't run right. But after the motor warms up its fine, its just getting it started. Any suggestions on what could be wrong? Thanks

Well - usually something like this would make me suspect the compression and timing first then the jetting in the carb. You might want to do a quick compression check although I do not know what the pressure should be for your bike. I would suspect at least 165PSI. You could have bought a bike that was run without an air filter or something like that.

I would also check the simple stuff - clean the air filter, drain the float bowl and tank and replace with fresh fuel (especially if your fuel is diluted with Ethenol !) and maybe even replace the spark plug.

If all this checks out OK and you still have the same thing going on, you might need to alter the low speed jetting (pilot jet).

Bought 2004 Kawasaki klx 125 and takes 20-30 kicks to start with choke on and even more when cold. Won't run right until motor warms up n takes a while for it to warm up. Runs fine after it does but it's...


Be certain the battery is in good condition. Install a new spark plug. Clean the carb and air filter. Use the throttle sparingly. The carb has a power valve that gives an extra shot of gas each time the throttle is twisted. Too many twists and the engine floods out. Please rate my answer. Thanks!

What is the choke position on 2004 klx 125, up or down


Down is choke "ON" and up is choke "OFF". Had same question and found on another site. Made carb adjusrment much easier after cleaning. Bike was new to me and runs great now.

Bike wont kick start or idle , it will coast


first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

How long has the bike been sitting? The gas may be bad or the carb might need to be cleaned out or choke may be sticking.

Hard to start kawaski barako 175


Hi and welcome to FixYa,

A known common issue with the Barako with either the kick or electric version specially when cold, in the early hours of the morning or if have not been used for some time. A couple of initial ideas to try:
  • leave the petc0ck open (even overnight);
  • before starting, twist the throttle a couple of times;
  • use the choke;
  • you may be interested to explore the possibility of modding the carb with one from an Eliminator.

In most instances, tyagaan lang yan but of course is a pain pag nagmamadali.

Good luck and thank you for asking FixYa.
