new here and need help with my just purchased 05 brute force 750. it only has 160 miles on it and was running great. first ride i sunk it and has not ran that great since. after sinking i changed oil and did all the normal things to dry out and rode the rest of the weekend. got it home and changed the oil again, changed spark plugs and put a new air filter and now does not have much power at all. so i check compression and its good. but notice when i had the spark plugs out the rear cylinder plug looks normal after running for about 30 minutes but the front plug looked brand new. so i checked to see if it was firing and it is. so make me think that the front carb is not putting gas to the cylinder. checked the fuel line going to carb and its getting fuel to there. any ideas????

 

at the front of your airbox there is a small carburetor vent canister. if u had it submerged in water for any amount of time water can get into your carburetors from there. it sounds like u need to take your carburetors apart and clean them out.
