Apparently I'm the only idiot to swamp my 700xx as I have searched and read until my eye balls were ready to fallout. After being out done by a 400ex in the mud pit I realized it was likely the 350lb difference and the air box setup isn't exactly ideal for such things. We pumped it out and I've changed the oil 5 times however now I have a knock that sounds like its on top the motor with or without load but more prominent when warmed up and taking off. I just pulled it apart to check the screens. there was a little crap on the tank screen but nothing on the crank screen(big pain in the a$$) I've also noticed that the oil level is inconsistent sometimes low and sometimes over full. This is why I assumed the screen was an issue and the crank oil level plug was over full. I am currently reassembling but will attempt to record the sound. I don't believe I have a bent rod or valve as it still makes great power but i just don't know what it could be (yes my oilf ilter is on correct). Thanks for any help you may have.
