water in motor

i just bought an 06 650 brute force this week and had it on the may mud run and it worked great. after playing in the mud all day the rad was packed full and i never noticed the heat light on the dash flashing untill i was almost home. so we stopped at a lake and were going to wash some of the mud out of the rad but i found a deep spot and the bike got a drink of water. it quit immediatly and we pulled it back. i just took it aprt today to drain the oil, belt case, and blow the water out of the cylinders. i checked the compression and it was about 75 to 80 psi in both cylinders. i was just wondering what the best way continue is. i've never drowned a bike before so i'm new with this. is there any special about the brute forces that i should know before i try to start it back up

Compression is going to be low because of the decompression mechanisms, in a 750 45 to 60 is acceptable

keep an eye on your oil it might be milky for a while depending on how much it drank, so buy a bunch of cheap oil and keep flushing the motor untill it looks normal again

Thumbs up

Drain the oil at least 4 times with transmission fluid(oil) and a cheap grade engine oil mixture while starting it for 15 secs between changes. 5th time change oil filter at same time and then use your regular 5-30w synthetic. Take plugs out and squirt transmission fluid down them and crank at same time.( oil Transmission oil acts like a detergent, helps clean). The bike will still smoke for approx a couple of mile then clear up.

Do a search; this has been covered many, many times and there are several good methods to remove the water. Also keep in mind that if the water was dirty, then the carbs are full of dirt and will need to be removed, disassembled and cleaned.
