Drain the carb bowl into a glass container. Let the container sit a few mins and see if it has layers or bubbles. If it does it has water in the gas.

 

Seeing how i drained and cleaned the carb today (took it compleetley apart, problem was before and still after) It may be in the tank so i will check tomarrow. But the last time i filled up i filled up another bike too and had no problems with it. I'll let you know Thanks Jordan

 

Its the fuel shut off switch, stright up and down doesnt work but say 8 O'clock it will come out. When i checked it thats what i saw come out and then it shut off so to speak. Put it on res and now it runs. So stupid

Oh now water in the fuel. Thanks again Jordan

 

My 1998 Is doing exactly the same thing. I have turn down the carb cleaned and soaked everything and it ran fine for a day the second day it was back to bogging out. I messed with the idle to solve the problem for the day. It also becomes harder to start the more I ride it throughout the day. I had to have the wife push start me several times.....Any ideas would be helpful. New probably the cooling fan is not coming on. I pulled the temp switch off and crossed the wires to simulate High temp and fan still did not start. Anyone know were to get a new fan at a decent price.

 

What does your plug look like? You made need a valve adjustment.

 

I cleaned my carb again and adjusted the air and it seem to be a little better, Now im waiting on the title so i can trade it in. I kind of dont want to for what they want to give but i want my 400. I like how reliable the mojave is and only hope the kfx/z is the same.

Ebay for the fan, i have seen a few go for cheap. Jordan

 

thanks for the help, I'll give ebay a look.

 

I bought a yfz450 fan from a local shop that sells used parts. made a few adjustments to the mounts and know I am back up and running. The next project will be the valves. Thanks again for the help.
