November 17, 200916 yr If it's wetting the plug when you try to start it you will have to get it dried out even if you have to turn bike upside down and pump it out

November 19, 200916 yr have you checked the carb float bowl? If the float is shot or stuck it will not stop fuel coming down from the tank, the float bowl will flood and fuel will get sucked neat into the crank case. if this is the case the bike won't run and you'll probably get a whiff of unburnt fuel from the exhaust as you kick it over. You can sometimes fix this by picking up the back of the bike and dropping it a foot or so which may unstick things. If the bike has been stood for a bit the fuel will go sticky and can cause this prob. I would try removing the carb and taking out the float. see if theres fuel in the float, if so it's holed, try dunking it in water and look for bubbles also. check the condition of the rubber on the pin that blocks off the fuelway. if v. worn replace. check angle of the tang on the float body that actuates the pin, it may want a tweak to compensate for wear on the rubber. once you are happy all is good dry the cases out thoroughly, use fresh fuel and try again. hope this helps,

January 19, 201016 yr the same happened to mine. I bought a Kehin carb as these are much better as the dellorto carbs always tend to break down.
