RE: F100000000

 Chuck stick to weed eaters!!!   It takes a pipe and chip to get 10hp out of 1 liter sport bike....  30hp, that's a
different story. This bike motors can run all day long at red line, provided they have good oil pressure. 
You can't even compare those engines to anything else other than another bike motor.  Truly marvels of engineering...

With restrictors, a built bike motor that makes more HP over a broader HP 
range WILL indeed still accelerate faster even if peak HP is the same as 
other motors. I see very high compession build-ups of those street engines 
being the primary trick in an intake restictor class.

People who advocate restrictors generally also forget their physics and that 
torque is what determines ultimate top speed, not HP.

 Chcuk, I don't think there is a class for the Legends in SCCA, NASA has a class for them.

RE: racing car counts

 David, the largest region for kart road racing in the country is in the south east.  The world karting
headquarters is nest to Lowe's speedway.  www.worldkarting.com along with the WKA schedule there's
another org called Big South Road Racing Series run out of Bama, and runs throughout the south including
Barber, www.bigsouthroadracing.com
   Sprint kart tracks are mainly in FLA, and there's a hug winter series for that as well as a good regular season.

Physics don't lie, doggy.  :->
HP only determines acceleration.

No argument Stan. Anything that can be done to decrease the gap between the

Re: Jetting on a Kawi

Brad Huelings told me that a Kaw in good condition should be jetted the same 
in both cylinders.

Good condition may be the key phrase.

I've seen motors with different length pipes on the each barrel as well as 
different deck heights.  I suppose the crank throws can get out of phase 
also. Different amounts of leakage on one head pipe vs. the other ,etc.

Air cleaners can be at different levels of "clog" too :->

RE: F1000 tidbits....

Chris,
I don't think Lee can use "Stohr" as a company name anymore. Not really sure 
how it alll worked out legally and why West isn't using "Stohr".

... or maybe they still are on paper, but "West" is easier for everyone now 
that Lee is competing against his old partners or whatever.

RE: Cooling the Kawi

I am not aware of any rule that would prevent having a fan to assist in
moving air through the radiators.  I believe a number of the AutoX crowd
do this, at least in the paddock area.  In racing there is sufficient
air flow that fans are not needed.  The only drawback in having a fan is
the necessity of having a large enough battery to run it for the amount
of time required.  If the fan is to be used when the car is on course,
it will have to be wired through the Master Battery switch so that when
the Master is turned off....ALL electrical power is turned of in the
car.

Thanks for the info Chuck.

Can I use a fan to help push/pull it through. I've found the the rads
generate a lot of heat, but flow through the rad isn't great because of
the oblique angle. At idle, I'm sure thay there is almost no air
