I was climbing a muddy incline in 1st gear. Reving it out pretty bad. The engine started knocking and turned off. I was forced too start it cause I wasn't able to push it out. Too muddy and slippery. I made it out, engine knocking like a mutha. Got to about 2 miles from my house and the engine locks up. Kick starter locks up. It has oil. It has water. I haven't opened it up yet. You think its the piston rings? Crank bearings? RTiming chain slipped? I think the sounds came out of top end. Crossing my fingers.
