Hey guys i need some advice here. This is what happened i went mudding in my brute force 750i carb on saturday and i decided to cross some deep muddy water and the bike just died. i sucked up water through the intake so i cleaned it on the spot and took my spark plugs out and cranked it, water shot out the spark plugs. i put it all back together and it runs but only with the choke on and i have no power it just bogs out. I know i have a little water in the oil so i bought everything to do a fush and change. My question is what next what do u guys suggest i do? Thanks in advance i appreciate it.

Did you put new plugs in it after the fact? Keep changing the oil (5-6 times). Yes, 5-6 times.

Do u think my carbs could also be part of the problem why its bogging out. Also when you say flush do you mean drain oil put the plug back in fill it up and drain it again or just let it run through? Oh and should i crank it evry time i change the oil so that everything gets flushed out? Thanks.

Sounds like you might have some trash in your carbs..You can take the bowls off and clean them out.. And yes crank it up and let it run every time you change the oil, so you get all the bad oil out.. Last time I swamped mine it took about 4 gallons of oil to get all the water out..(about 6 oil changes)..You can also put some seafoam in it and it will help get the water out faster..

Mudbound, I've had friends sink their bikes like this also and they like to dry the crankcase out by using diesel fuel in place of oil. Top her off and idle to light throttle for 3- 5 minutes. Drain and repeat 3 or 4 times. Diesel absorbs water like a sponge! You might want to stand her straight up overnight with the spark plugs pulled and let the water drain from the cylinders out the tailpipe.

You definetely have water in your carbs .On the bootom of the carbs (the bowls) there is a small hose .These are the drain hoses. Next to them you will see a small screw .Open the screw and let the carbs drain completely.It also might help to put some drygas in the tank to remove any water left in the carb little nooks.

Well heres an update, so far ive done the all the flushes and my oil is now free of water 6 flushes to be exact. i changed the spark plugs and air filter. now the problem i have is i cleaned my carbs but i didnt take them completely apart because i dont know what to expect and i dont wanna end up trashing them. So i put everything back together and the bike fires up but i still have a miss while idling with the choke on (which is the only way its stays on). also same thing i have no power and im backfiring like crazy when i move it around, and i also noticed that my exaust is alot hotter then usual which i would think is because im runing really lean. So what do u guys think it could be, do u think my carbs are still dirty or is there a possibility that water got in my gas tank. Thanks again for all the help.

Debris in idle / pilot jet. No fuel, lean....requires choke to run.....
