So last Sunday I went out riding and tried to cross mud hole and failed. The quad cut off and I had to be pulled out but before that my buddy jumped on it and tried to crank it while it was still in the water so some got in thru the exhaust. I couldn't get it to fire again so the next day I drained the oil in the pan and crankcase and it was fine...not milky at all. I did get it to run and it spit muddy water out of the exhaust for a while but then quit. I did take the plug out first to puch any water out but none come out. The plug was nuddy as well. It seems to run fine now...idles ok and goes thru the gears fine and all. Also the belt housing was FULL of water...it POURED out when I removed the plug. My questions are...is the quad ok? I'm just not sure seeing in how it seemed there was muddy water possibly in the cylinder...and should I take my belt cover off and clean that out somehow? I'm just curious because I rode a little bit not even 20 mins ago and it just cut off twice for no reason. I just want some opinions on if it's ok or what should I do? Thanks guys!
