i have a 99 300 praire 4x4 with 26x12x12 , 26x9.5x12 vampires. i am very pleased with my machine so far. i have about 400 miles on it now. i was wondering if anyone knew of a way to keep water from getting in the trans. it has only happened twice but i would like to run the two rear vents somewhere higher on the bike.is there a kit for this or do i have to rig up a device to fit it?

 

I have a 300 prarie also. I haven't got water in the trans yet, but I know I'm bound to sooner or later. How did you get the water out? Did you have any problems afterwards?

 

after my bike was winched out of the bayou, i just let the enging idle for about 10-15 minutes. at first the belt still slipped but ounce you get it rolling it dries off with no problems. i have takin the cover off the trans to clean inside of it and inspect things and things are looking real good so far. i ride in some very extreme bayous and some real louisiana gumbo mud. i don't abuse my machine but i do push it to the extreme.
hope this helps

 

The only time I got my belt wet, water over the front rack, I dried out the belt by going up and down a long straight away. It would slip at first then gain speed. My dad said the transmission outlet was pumping the water out from behind the storage box as I drove away.
The air box to carb. inlet is lower than I'd like it to be, but I have went swimming with the rear fenders barely over the water with no problem, you just have to keep that front end up.
They are great swimmers though

 

my praire got the water in it from one of the rear vents. it was in water just up to the seat.

 

hey i dont know if this will help but i have a it 200 dirt bike and i used to get water in crank case crossing very deep river so i drilled a hole in the airbox and screwed a nipple into it and ran a new vent hose to nipple and siliconed around it just to be safe and it works mint dont see why it wouldn't work on your machine.
