You say there is alot of signs that sand and water entered the engine..... As you probably know...Do not try to start it.... I would drain the oil...and cooler tank. Definately tear down the carb and clean throughly...
If you have the tools and ability...I would probably even pull the head and check what kind of damage you did..(make sure the valves are seated) Dirt in the cylinder can lead to really fast wear.... If your not going to tear the engine down, I would say to change your oil many times until it is clear and not milky from the water.

Dear Wideopen, after a long day of riding at the Walden dunes in northern Co. my 400ex stopped with a clanking noise. Long story short- fried crank , sand in the cylinder head. I also have a k&n filter(with outerwear)and a white bro pipe. The dealership had no explanation for these conditions and the jacka$$ for honda care said it would not be covered under warranty.How much you ask? $2000. My bike was not a year old. I sincerely hope you have much better luck. Thanks Honda care.

K&N are awesome performance but I personly have seen many engines wasted due to dust and sand getting threw the well oiled K&N including a 96' Ford Powerstroke diesel that sucked dust costing $5,000.00 in damage! As for your engine, the blue smoke says it all, most likley a wasted top end. I would do what sAyIt_fmf said. If the oil changes dont help a new bore job and a fresh top end is headed your way... heck may as well get the big bore kit, same cost

Let's see.... You blame Honda for your aftermarket filter allowing sand into the engine, thus causing severe engine damage?
How would you feel if you were an engine builder and one of your clients had you build him an expensive engine, took it to the dunes, sucked sand, then came back to you yelling that he wanted you to build him a new engine. Homey don't think so...
I do not see where Honda is at fault in your case. If I were the Honda rep, I would not have warrantied your engine either...

Dear Gabby, I don't know why I did not consult you first concerning aftermarket performance parts. Have you ever felt that your genius is being wasted in these forums.Well ,I am putting my bike back to stock after reading your insightful analogy. I think Honda is lucky to have such a great fan as yourself. Do you smoke a pipe while you write in these forums?

good point gabe..
however, 1 question: What are K&N's good for then??? allowing more air in??? are they better in wet conditions??? so installing a 40 dollar K&N with no holes in the airbox allows just as much as as a stock filter with no lid???? hmmm....
should i get rid of my K&N??? i usually ride in dusty conditions.. never sand tho..
