12.A. PRODUCTION: “P”
The same engine must be used that was originally installed in the
specific motorcycle at the time of production and must meet the
definition set in the ‘P’ frame class (Ch 4). Original equipment
must include cylinders, cases (crankcases), heads, carburetion or
throttle body (stock venturi), kick-starter or electric starter.
Displacement determines the class. Increased displacement beyond
the class limit will place the motorcycle in the correct class.
GASOLINE ONLY. Fuel not permitted in this class. See section
2.F.
Setting a record with a production frame and production engine . . . Priceless
Setting a record with a modified frame, special construction frame, or streamliner AND a production engine . . . Worthless.
Oh yeah, you can do it, and you can wave around a nifty certificate. But have you REALLY accomplished anything. Nobody will ever break the record because the next guy will just pick some other empty record.
Shoot Dean, I don't see how it would be "worthless" to set a number with a production engine.
The point is moot now, and I told Brian that I thought I had read something to that effect before, so we're just talking hypothetical situations now, but really, everyone has to start somewhere, and if one could pull a piece of paper on the first trip with a new bike, why not.
We have to enter it into some class to run, and this is the first time this bike is going to the salt. Call it shake down for the chassis and seeing how well our aero package works. We're really just having fun with this, and aren't about to let lack of funds to build an all out engine keep us from testing the chassis. We can always enter a more competitive class once we've got the engine pumped up, maybe next year. Let's face it though, with a 30 year old single cylinder engine design, what are our chances of actually being competitive?
Really, we're just taking what we have and doing the best we can with it. That's the challenge we've set for our selves, and we're darn sure going to have a good time doing it.
