today i went mudrideing cuz it just rained and i decide to go into this canal it was waist deep i go into it i was 1/4 through and the bike starts to bog down or sounds like about to kill so i gove it alittle mor gas and then it kills i got off and it starts back up and then half way through the same thig happens and it starts back up and when i give it gas it would kill i tryed it agian and the same thing happen when i give it gas it would kill when i got it to start up i rode around and went back to the canal and crossed it and it killed again when it start back up but when i hit the gas it would die this only happens when i go into deep water not in shallow wat u think is going on is it the spark plug or something electric is getting wet

 

Take ALL of your electrical connectors and spark plug boot loose and apply dielectric grease to them. This helps a great deal. I finally added an exhaust snorkel to my HMF and it runs all day when submerged.

 

Also look at the carb vents...the open ends need to be out of the water. They might not be routed right.
