I was riding my 2001 Honda Rancher 350 through a deep mudhole and water got in the airbox. My buddies and I flipped it up to get the water out, and after that it started to smoke when I cranked it up. I was wondering if you knew how to make it stop smoking.
Have you tried one of the Nicotine Patches? Seriously, what most likely happened was that when you tipped it up to drain water out of the air box, you also drained crankcase oil into the air box through the crankcase breather tube. I bet if you check the air box you will find an overabundance of black oil. Your air filter is saturated with this motor oil and it is being sucked into the engine and being burned. Hence the smoke. Clean the air filter and re-oil with foam filter oil and clean out the air box and the smoking should be stopped. If it doesn’t then water and mud got into the cylinder and scored the cylinder wall. This would mean a first over piston set and a bore job. Let’s hope it is the former and not the latter, Son!
