Sitting in the rain shouldn't cause water in the cylinders. If you're seeing water around the base of the spark plugs that would mean the drain holes are plugged up. There are two holes down by the plug bases that often plug up with crud. Just poke them out with a piece of wire. If you are finding water inside the cylinder about the only way for that to happen is a failed head gasket. It's possible to get some moisture in the cylinders if the bike sits in wet weather for a long time just through condensation.

it might be possible for water to get in the cylinder head if your breather washer is rotten or missing. could be leaking in there you might check and make sure it's all tight and seal are in good condition? with all the rain we've had it might leak where it hasn't in the past. just a thought. i had a 1200 to stick up because it got rained in when i new it couldn't.:shock:

If you do have water inside the combustion chamber, it's more than likely there because your head gasket is leaking and allowing coolant to leak in!

make sure it doesn't have any antifreeze in it. is it just water or is it antifreeze? if it's anti freeze i agree with wingle. in your post you say water not antifreeze?

I can't see how that hole could be letting water in. It's covered normally with the little lid on the tank pod. Even if the gaskets on the pod were bad I think water would tend to run downhill and drip into the fuel filler tray. That tray has a drain tube.

In order to bend a rod, you'd have to have a significant amount of water in there. I'd think at least a tablespoon or so.

That water, would have to get past the lid, find the hole and drip down past the air cleaner to the plenum, pool up enough to get over the ridge to the carburetor air intake, run into the carb and somehow not sink to the bottom, as water does normally, then overflow into the intake tube and find an open intake valve.

Not impossible, I suppose. But the smart money is on an alternate path.

Why would you let your poor old 1200 sit in the rain?

On my old 84, the water would collect at the base of the spark plug and slowly seep down the threads into the chamber. Just an issue of the age of the bike and the number of changes. I would put a small bead of high temp silicone around the base and no problem.

Not sure exactly what the plugs cavities are like on the 1200, but if they are like my 1100 this could be an issue. Best way to check is wait for a dry day, run the bike, and spray a little bit of water around the plug - if you see air bubbles (seeping up the threads to the outside) you'll know this is an issue.

But I agree with Bike'n'Dennis - to cause that kind of damage it seems likely something else is hinky is going on...

raining 6 in in a day might have a little to do with it. theres only one way it has to go in through the carbs and intake if it's not leaking by the plugs:shock: and remember it water not coolant.

I have an old two stroke where the plug sits in a hole under the gas tank. I have never had water find it's way past the threads and into the combustion chamber in 200,000 miles of riding. the water must have found it's way into your cylinder by another means or you left the plug loose

Normally I would agree - but in this instance, the spark plug hole was slightly egg-shaped if you measured the ID.
It doesn't matter, the bike is long dead...I still miss that ride.
