Help!!!

Have you drained the carb? Sounds like it could be water in the carb to me. My X90 was acting like that a while back and it does not have a drain on the carb's bowl. So I took the carb off the bike and checked the bowl, it had about a tablespoon of water in it.

Kinda depends on what 'got drowned' means.

If you got stuck in the mud with water just over the axles, that's one thing.

If you were standing on your seat, ankle deep in water, that's another.

Did the engine suck in any water (was it running or trying to run when it went underwater)?

You don't say, but I presume that after the 'set-up' you rode it for the balance of the day to no ill effect?

In which case, maybe it was indeed the washing off that caused the problem?

Clean your filter. An inspection of it should tell you to what extent it 'got drowned'. With the filter off, make sure the intake between the filter and the carb is clean. There is a 'well' before the carb that can accumulate junk.

If that area is dirty, certainly take the carb off and clean it up. CRC brakleen works great for that.

You can drain the bowl via the plug on the bottom (17mm I recall?) of the bowl.

Make sure everything is correctly assembled and correctly tightened....reed cage flange, carb boots and such.

Are the boots in good condition? No cracks that could have sucked in some water?

Check your tranny oil. Heck...just change it on GP. If it looks like baby poop or is milky, that's another indication you sucked in some water.

The 'set up' doesn't sound like a good thing. Depending on how bad it was, you could cause some serious damage to your bike and to yourself if you got in 'over your head.'

All puddles are the same depth gauged by their surface! Which of course has squat to do with what lies beneath.

Assume every puddle is over your head (literally and figuratively) until you know otherwise.

Cheers!
