On a 99 YZ 250 my friend and I are trying to figure out what is causing this fuel puddle at the rear of the carb. What I know now is that the problem will happen running or fuel will accumulate here even if the bike is not running. This situation is causing a rich running condition and poor engine performance. The needle has been replaced but not the seat. The reed pedels are new. The float level has been check many many times. No external leaks. http://i217.photobucket.com/albums/cc230/claykyle/ATT00203.jpg Has anyone had this problem and how was it fixed? The fuel cut solenoid has been replaced, we are running out of ideas for a fix for this. any help would be appreciated since we have a three day trip planned in a week.
