RM 250 injested some water

[QUOTE="rmc_olderthandirt, post: 1316484, member: 68872"] Did you have an air cleaner on when you dropped into this puddle? I would have expected the air cleaner to strain the water and keep the debris out. If you have some debris in there then there is a good chance that it is parts of your engine, not dirt from the outside. I have flooded a number of two stroke engines and have always lucked out. I have been able to simply dry the engine out and start them back up. You must do this soon after the flooding, however, as water sitting around for a few days in places it didn't belong will wreck havoc on the internal engine parts. In all the cases where I have flooded an engine, however, the engine was either off or at low power. If you were "on the pipe" trying to get through that puddle when it sucked water then all sorts of damage could have occurred. Since water won't compress the piston going up or down (two strokes) will come to a sudden stop when it encounters water. This can break pistons, rods or even the crank. On a two stroke is is possible that the intense back pressure can destroy the reeds on the pistons down stroke. If you have compression and don't have any other reason to suspect piston damage then I would suspect that you still have some water down in the lower end. You might also have water in the carburetor. Here is what I would do: Take the gas tank off, and drain the gas out of the carburetor. Note: draining the carb is optional, it will do it on its own in the next steps, but you may not like where it drains to.... Pull the plug. Turn the bike upside down. Yep, flip it over and let it rest on the handlebars. This will allow any water in the bottom end to drain out through the spark plug hole. Crank the throttle wide open, hold it there (the bike resting on the grip will probably hold it). Put it in first gear. This will allow you to spin the rear wheel by hand to crank the engine over. Lots easier than the kick starter. Spray a lot of WD-40 in the carburetor as you turn the rear wheel. You want it to be running out the spark plug hole. Let is sit upside down for a few hours to get as much as possible to drain out. While you are waiting, drain a bit of gas out of the tank into a clear jar to check for water. Turn it back right side up, put it back together, try starting it again. Rod [/QUOTE]
