A reed valve in a 2 stroke engine is basically a way to prevent the fuel/air mixture from being blown back into the carb. If yours keep failing, the most likely reason is that you have bought cheap reeds. There should also be a reed valve support on the carb side. this is to stop the valve from vibrating and bending the wrong way.

Small pinholes in the reed valves


Yes mate... It is hard to say without seeing the reed valve but I guaranty a dodgy reed valve will make running and tuning the bike a nightmare. Your reeds need to seal perfectly and open and close about 2-3 times a second so if any cracks, holes or damage to them then they will never seal correctly which will allow blow back through the carbi and incorrect air and fuel mix to be sucked into the motor. best solution buy a V force reed kit it replaces the entire cage and reeds just bolts in (4 bolts) I sell them for about $160 delivered, or if your know what you are doing then you can just replace the reed petals with new... About $60 ishwww.motoxpartsonline.com

Try a .162 main jet,48 power jet,carb on 3 or 4th clip to the main jet.
Some boyser power reeds might help also about atotal of 60 to 75 bucks for the whole deal and that should get you to bonzai state in no time.

What is the year model of my KX250


Any Kawasaki dealer can take that frame number and tell you exactly what you have providing the bike is reasonably current. They are about the only ones who have the code list. Give a dealer a phone call.
