hi everyone.. what would cause my 99 honda 300 to stall and cut out ( lose power ) when going thru water?

 

check that ur plug boot is not getting wet on the inside and put some die electric grease inside the boot and reinstall it

 

DO a search, a guy had this problem with his Recon 250, I posted alot of info there so check it out.

 

i have that exact same quad and the exact same problem...if u find out what it is let me know.....i was told that it was the carb over flow hose...when that gets under water the quad will stall and not have any power...but idk if that is it or not

 

Put a T fitting on the carb vent lines... this will stop all problems associated with the lines.

Carb, Tfitting, Hos up to base of handle bars, hose down as normal, with a 60* angle cut at the end....

For best water protection. do this with ALL vent lines.

 

I dont know about the Tfitting as you are still opening yourself up to water infiltration through the original line. I completly removed the stock line and ran a new line from the carb right to the 3rd headlight on my foreman. Didnt want to chance even a splice in the line as I experienced problem with air flow previoulsy and I didnt want to affect the carb in any way.

Waterproffing all electrical connections is extremely important, and once again check the Triangle ATV site under tips for more info.
