i rode my ttr 125 through a mud puddle up to my hips...i got it out and it started up without skipping a beat...now a couple weeks later it wont start and i have oil coming out of my muffler..
oil out off the muffler sounds like you got a little brother playing tricks on you.First off i'd check your engine breather pipe which is userly under the airbox on top the crankcase somewhere.It sounds like you got mud in the pipe which will cause excesive pressure in the crankcase and would result in a smoking exhaust.If this was the case oil will build up in the cylinder and then the exhaust and on to the muffler.And then you go to start the bike and hey pressto a oil fouled sparkplug.This is a possibility and would also pay to look in the air box for oil as well as it will blow back into the airbox and would result in the same senario.The only other thing to do is take the top of your motor and explore it and find the problem.
oh shit
