hey im new in this forum i have a honda ex 400 2002 and have exhaust yoshimura and fullskitplate wheels carbon fiber but i ride this morning and passing to the river the 400 began to fail and turn off and never starting again what would be the problem? please help i dont speak inglish very much but i appreciate the help.....

 

Did you go through the river?
Possibly did you get water in the airbox and in turn it got into the carburetor and engine?
That would cause the engine to stall.

 

or if you got water bewteen the spark plag and boot. place some dielectric grease in the spark plug boot

 

is not really deep ,maybe 2 feet but all the cables are wet . i friend told me he could be the estator .....

 

the water reached to the skitplate
