My son crashed and put a hole in his radiater about 30 miles out. We managed ruin drinking water in it to hey back to the truck. I noticed steam from the exhaust pulled the header pipe and yup water in the cylinder. Cycled the piston with the exhaust off several times to get the water out, ordered head gasket o rings online. Almost 2 weeks later parts showed and I realized I couldn't kick it over. Wouldn't budge. So I tapped around the cylinder with a dead blow mallet until I got a little wiggle, sprayed some wd40 and finally got the piston to cycle. I coated the cylinder with2 stroke oil but it really sounds bad now. Going to pull the head tomorrow. It's this common? What should o be looking for?

Check for any scoring or marks on the bore.Also check the big end bearing.If water has entered,the bearing could of seized or be water damaged.It could of been that some dust or dirt entered when you were turning it over to rid it of water.All fixable though...........
Good Luck

So here's some tips I've learned if you find yourself in my position. Get as much water if not all out rite away. Pull the cylinder and tip the bike up side down if you have to to get the water out. Make sure the piston is at top dead center. I'm kicking myself that I didn't do this but I didn't know. Know I do.
Basically there was a small amount of water at the bottom of the crankcase and of course it was almost at bottom dead center so the crankshaft connecting rod bearing was sitting in water. It looks like coffee. Really fricken gross coffee. There is no movement in the connecting rod or the crankshaft thati can feel but it does sound loud when i cycle the crankshaft but maybe I'm being paranoid. I cleaned it out the best I could. Not sure of spraying brake cleaner in there would bea good idea soi just dumped some 2 stroke oil all over the bearings for now. Any suggestions much appreciated

One more thing. Having a hard time finding anything on checking the specs on the head and cylinder. Obviously blew a gasket but it's not apparent wich one. Normally it would be with a strait edge and feeler gauges on the gasket mating surfaces bit this uses 2 o rings...
