ko, here it is. I have a 2007 420 FM and I can ride trail and lite mud all day, no problems. BUT, when I go to really play and get in some water, this thing will stall. Air box has always been bone dry. It will start back up right away but then under load, it stalls again! I have dielectric greased the spark plug and all the electrical connections I can get to.

Any suggestions, I really like the machine but this is getting frustrating!

Thanks guys

I would speculate that problems caused by water are High Voltage problems. At low voltage, the water wouldn't cause any problems, in the short term.

Meaning, if you are running along and hit a puddle, and suddenly the machine cuts off, it aint because a low voltage circuit got wet. Look at the high Voltage circuits.

I think the spark plug or coil is where your problem lies.
