Hey everyone, I picked up a 2006 WR250F today and it runs pretty bad. It is a completely stock bike except the rear fender is a YZ fender. I can choke the bike and the idle speeds up and it sounds good. When I let off on the choke it will idle rough and doesn't want to take any throttle. Once I get the bike revved up it backfires a ton on decel. I rode the bike and it hesitates and spits and sputters. I think it may have an air leak somewhere? I pulled the air filter and the bottom of the box had an ounce or 2 of water in it. The filter was a little ratty so I ordered a new one. My hot start cable was really loose so I adjusted that but haven't ran it. I'll probably mess with it a little more tomorrow and if I don't have results I'll pull the carb and clean it. Any suggestions on what I should check?
