Need a bit more info to pinpoint your problem.....After it starts acting up, can you shut it off for a min or two and then will the bike run normal again for ten more minutes? If if does it probably is a fuel problem. If it doesn't it is probably an electrical problem. On the fuel problem there are a couple of things to check. There is a fuel filter on the pet**** on the inside of the fuel tank. It will plug sometimes and needs to be cleaned. Make sure the vent line from the gas cap is unrestricted, if it has a one way valve they can often fail and cause a similar problem. Make sure the vent tubes on the carb are also unrestricted. Your float level in the carb could be too low causing a fuel starvation problem. I had a neighbor down the street describe to me the same problem....after riding the bike I found out he was fouling spark plugs not having a fuel starvation problem. I simply rejetted the bike and it has been running great ever since. Try to give as much info as you can when you describe the problem and you'll get a lot more help from everyone here!ira sprouse said:My son's kx 65 runs fine for 10 minutes or so and then acts like it is starving for fuel. Does anyone have any sugestions?
The clip should be in the middle position. The first position, being the very top......is the leanest position. The bottom position usually #5 is the richest. Put the clip in the middle and return the jets to the stock size and run the bike now that the float bowl isn't running out of gas.ira sprouse said:If I move the clip off the first ring (richest) the power curve is very speratic. 1/4 throttle on up, if you hold the throttle at different positions the engine is always on and off the pipe even at low end positions where the pipe (power band) is not needed.
