Help! I think I may have messed up my engine

[HondaRaceReady]

After a day of riding in the mud, I was powerwashing it with a plug in the exhaust pipe. Afterwards, I was trying to warm up the bike to dry it off some, but I forgot the plug was still in. Everyone here knows its hard to start a cold 400ex. I thought mine was warm, so I tried no choke, and it died after a second. Then I put on the full choke, tried it twice, and it died after 2 seconds both times. Then I put it on half choke, tried twice more. It ran for about 3-4 seconds both tries. And then I realized the plug was in. I pulled it out, and there was some soot on it. After a while the bike started on half choke, but did I damage my engine at all? I think if some serious pressure built up in the engine the plug would blow out, right? The bike is only 4 weeks old, so I doubt the exhaust could escape through any bad seals. As long as the spark plug doesn't blow out, it's ok, right?

Your engine is fine. I dont know that it really could mess up anything doing that. All it does is kill it because the exhaust has nowhere to go.

nothing to fear.
your bike is fine. no damage done.

sleep tight, and have happy dreams...

I agree your engine should be ok....you just momentarily asphyxiated the engine if you will. Might want to check the plug and see if it was fouled though.
