Just my 2 cents...

According to Webb's bike, apparently it does. Politically correct cover-up? These guys are motorcycle racers, not the fucking CIA, they're not "covering" anything up you boob.

4 strokes smoke from oil blowing past the rings or some other way.

Also consider there is record breaking heat along the freezing cold damp coast in CA tonight.

Racers are always told to "blame electrical" "blame spark plug"

They cover up lots of shit. Matthes has mentioned this before also.

"Ran out of fuel due to fuel boiling" = This big bore is a thirsty fucker and it ran dry!

So you are saying it's completely normal for Coop's bike to smoke more than a YZ250 two stroke?

That's interesting.

Does that have any affect on the "green theory" that started the fooper movement in the first place? I'm curious to hear your thoughts on this.

I wouldn't say they don't cover anything up, especially not Webb. Remember the 250 national title for Martin and coop accidentally "stalled it" In a flat corner and Martin got by to seal up the title?

I can tell you this. I dont know anyone whos ever boiled fuel and fuel boiling doesnt affect efi rhe way it could a carb...IF it even did.

But my big bore runs about the equivalent of 14 main jet sizes bigger than stock. So it must boil away a LOT of fuel.

Sweet Jesus, your reading comprehension hovers right around zero, doesn't it? I never said anything about what his bike normally does, let alone anything about "green theory" - whatever that is. What I did say is that these guys aren't running some kind of cover-up about what happens when something goes wrong. Believe it or not, sometimes shit just happens - even when you're dealing with expensive "works" motorcycle parts. Either the top guys are a bunch of homeschooled buffoons, or they're some kind of political thinking geniuses who can make up excuses on the fly to cover up issues with their teams. Which is it?

You are correct, thank you for making my point for me. That being said, I agree with you when you state the fact that "shit just happens" when racing four strokes. I agree wholeheartedly.

The part I struggle with is the fact that AMA pro racing has adopted a rulebook that favors 4 stroke engines that spin at 15,000 rpm and have 100's of moving parts to achieve the same HP numbers of 2 strokes with 10% of the moving parts and cost involved. In addition to that, the racing isn't nearly as exciting (in my opinion)

It just doesn't make sense to me, does it make sense to you?

From the standpoint of manufacturers needing to sell bikes it makes perfect sense as EPA rules, manufacturing, ease of riding them. made 4 strokes the dominate player, now they are here to stay even if they cost more to own and maintain (more profit for industry) and are less exciting to watch. I was a four stroke guy, but saw the light, but have seen both sides to the coin. Either way at least there's growth in other areas of our industry.

It still has a vent hose like other bikes, just cap is hidden, I rode a 12,15 and 16 but realized 2 strokes are where its at if anything a cooling issue with the bike or gas, makes me think back to boiling gas during dungey's outdoor 250F outdoor season.

Boiling gas? At 51 degrees.

That wasn't the problem.
