How was that? did ktm said anything about it?

What do you mean? I know Denoble didn't look too happy.

Well by saying "how was that" i'm not trying to know how could it blow. Just blows.

I'm impressed because it's not very common a quad blow it's engine after 3 races. And worse if it was being assisted by a ktm team...

Well actually I shouldn't say that it blew up. It filled the air with smoke and he pulled off and pushed it back and didn't race in the 2nd moto so it must have been something serious.

That happened on Saturday too? I know I went to Tigerton on Sunday.

I am just repeating what I was told by the dealer repairing it, and did not see this myself. "The top end is worn severely and the engine has sand inside the head and cylinder. At some point he was racing with no air filter on at all." So I don't think we have a build quality issue here.

Wow that's weird. Great to know that it isn't KTM manufacturing's fault.

Maybe the filter was not put correctly or something cracked in the carb...sand inside that was bad...

Baldwin told me about that issue... It seems some people haven't been putting the air filter on correctly and it sucks dirt, and then we know what happens from there...........

That may be a problem some are having, but that is not what they said. I was told "He was racing without a filter". Like voluntarily not using any air filter.

Well, Mr. John Maley touches this issue is this clip. Watch at 2:40

When he checks it, you can her some click's. Air filter well seated is very important and should be double checked

Alright there are so many stories going around about this. First off what I was told from a reputable source is that the quad was lent from a dealer up near Appleton/GB area ( possibly Team 2 ) to a racer and Denoble actually got on the quad unknowing to the dealer and rode the quad. I'm not sure about the whole air filter issue, but what I do know as being an owner of an sx is that re-jetting these machines is one thing HAVE to do once getting one of these machines. They are jetted so lean from the factory that you WILL most likely blow it up being untouched.

Apparently he said that they got it from the dealer, threw some stickers on it, and took it out to the track not touching a thing. Now if he's that dumb to run it without a filter, then of course he's asking for issues. Im sure we'll find out more, but out of the dozens of SX's out there at this time, this is the only issue I"ve ever heard with the KTM. And it sounds like its an issue do to rider stupidity.

Take care of your machines, and they'll take care of you reliably!!! Being ignorant will get your no where.
