2013 EC200 water in crankcase

Hi all,

Have a bit of a problem on my hands... I last rode my 2013 ec200 around a month a go and as usual gave it a full wash down afterwards. I went to start it up yesterday and could tell I wasn't getting spark so I pulled the plug and found water on the end of it...

Long story short some water got in the exhaust when it was last cleaned and worked its way down to the bottom of the crankcase and sat their unnoticed for a month. I've drained it, flushed the crankcase and pulled the top end for a closer look at the crank. There's no visible rust on the crank but I'm worried about the main bearings.

Should I go to the trouble if splitting the cases now to inspect them or keep riding until it's due for a proper strip down? The bike has a total of 60 hours of trail riding on it at the moment.
 
I'm concerned about how water got in there from just cleaning. I can't imagine it coming through the exhaust unless the hose was run straight into the pipe for a while.

You would have to have at least an inch of water in the crank case to affect the bearings. The rod bearing may have been in the water. But,you would see a water line on the crank filets.

I washed it with a pressure washer (which I normally never do) without my exhaust bung as I had lost it. I found water in the exhaust but now you've said that I did get stuck in some very deep mud that day so it's possible muddy water got in else where.

I will have a closer look at the crank for any water lines. Quite a bit came out but unsure if it would have sat higher than an inch or not.
 
After a closer inspection tonight it looks like the water may have just sat on top of the piston until I started trying to kick the bike over - is that plausible?

The rings are a little rusty but other than that everything looks normal.

I did the same on my 15 200. The water enters the filter box via the openings in the side panels. I always use a pressure washer. This was one of the first times I washed it, and I tried to start it directly afterwards. It didn't...
Then it sat for a day or two until I tried again, then I saw the water at the spark plug. I drained the crank case thru the draining plug, and there was some cc of water coming out.
When I checked the air filter box, and water was still standing there. Then I removed the plug (that should have been a one-way valve, but gets clogged immediately) in the bottom of the box, and have never had the problem since.
 
I guess I could see that if the airbox drain was blocked. LTCP, it looks like you are on your way.
 
water intrusion

Not convinced water would get through airbox and carb without engine running. But it is a little disheartening to pull the side covers off and see just how vulnerable the intake is to water intrusion. I would never try deep water crossing on my ec300 because of it. One year I rode the Alligator Enduro here in Florida right after flooding rains, my IT200 Yamaha was up to the triple clamps when I crossed the river, nothing but handle bars showing. Made it through and passed fifty watered out bikes. Not too sure my Gasser in that environment would do so good. Just clean out the water, rust, free up rings and you should be alright.

I agree. But in my case I did try to start it with water in the airbox. I believe that was when it was sucked in.

Yeah the airbox design is terrible. Pain in the arse getting the filter in and out of it and it's always full of rubbish after a ride.
 
I'm with Anders, I tossed the air box drain valve. The rear tire sends a lot of crude straight into the air box if you haven't sealed up the inner fender area. I haven't had any problems with water crossings, more problems with pressure washing and the drain holding water.
