DeCal Works Huge Plastic Inventory of UFO and Polisport kits.
Yes, it's true, Cairoli's 2009 Yamaha was a 400cc engine. He thought it worked better, because he could race it the whole moto. This is why his choise to race the 350 this year was easy. KTM punched his 350 out to a 400 and he has the same type of bike that he won the Championship on the year before.
Alessi on the other hand can't switch to the 450 now. It's too late. He had to make that choise before the 2010 outdoor series started and they will not let him switch now. All the parts had to be ordered for the 350 and if he wanted to switch to the 450 now, he wouldn't have all the factory parts he would need. Plus the 450 doesn't have linkage and we all know how important that is. We won't even go there at this point. Poor Mike Alessi has made his choise and he chose the 350 and now he has to deal with getting bad starts and pulled on deep tracks.
Why bother comparing?
And pmcc a better title to your thread would've been 'Cairoli nails another holeshot'
But fuckin really!?!?
'Riders were faced with tricky conditions following heavy overnight rain on the circuit and high humidity on race day that hung over the track in the form of mist. Visibility was an issue and a number of riders opted to discard their goggles during the races.'

Per the AMA Rule Book:
3.3 Engines
a. Engines are restricted to a single cylinder.
b. Engine displacement shall be recorded in cubic centimeters.
c. Supercharging or turbo charging is not permitted.
d. Cylinder bore may be increased to achieve the displacement limit on
motorcycles homologated for competition, provided that any kits or
parts used to increase engine displacement (to the approved class
limit) must use items that have been approved by AMA Pro Racing.
e. Stroke must remain the same as the homologated model.
f. Material and castings of cylinders, cylinder heads, and crankcases
must be the same as an originally approved model of the same
manufacturer. Material may be added or removed from these items.
Cylinder liners or coating may be replaced or added provided
the original cylinder casting is utilized.
g. For 4-stroke engines the original intake and exhaust valve angle
must remain the same as on the homologated model.

KTM used their one time "Exemption Rule" with Lance Smail back in 1997 with the KTM 550 4 stroke in AMA SX! First time a 4 stroke ever qualified for a 250 Main Event. Yamaha used theirs with with Henry and the YZ 400F, Suzuki with Tortelli and the RMZ 450, Honda with Ryno and the CRF 450, and KTM with Smail. To my knowledge Kawasaki has never used their exemption yet. All the 250F's were intoduced as production based models because the exemptions were used up (not Kawi, they just waited until the production bike was ready). Here is a link to Lance Smail's 1997 KTM 550 4-Stroke! Pretty sweet looking bike.

In no way does that compare to calling yourself Eywa, having some blue monkey avatar eye as your actual avatar, another one in your sig and then naming your location as a fictional planet from the movie...
Like I said, I loved the movie too but really... Are you just really excited to get a change from your Darth Vader costume?!?! hahaha
