Production applies to the motorcycle configuration, not the engine. There are no A- production or M- production just like there is no sidecar production or streamliner production. A production bike has to look stock.... no after market exhaust or fairings etc. The engine can be modified, as long as the changes are not visable, ie pistons & cams changes are ok but you can't put a turbo on it or nitrous. Also, to run in production you must run gasoline, not fuel. So what you describe would be an A or M class bike, depending on what type of frame & how much the frame has been altered.
Production classes I've seen are:
P-P production bike
P-PP production pushrod
P-V production vintage
P-PB production blown
P-PPB production pushrod blown
Hope that helps.

Matt,
I agree with you in so far as the first P applies to the bike, must be stock appearing, etc, and also agree with limitations on the engine, must use OEM heads, Carbs, Jugs, and case(s) no blown unless factory, no fuel.
Where we disagree is that
P-P is production/production (for production bike {i.e. class} with production engine {i.e. engine class})
clearly by rule qutoed previously a special construction frame or a modified frame (iaw with current rules) with a production engine would be most properly be
A-P or M-P, clearly a class engine combination currently allowed for by rule(s), but yet no designated vehicle entry ID or records near as I can tell.
By rule 7.D.4 (pg 99, 2006 edition SCTA) engine class "P" allowed in all frame classes except "SC" which seems real fair to the factory harleys that had a factory sidecar. Perhaps this rule is a typo-inversion???
So we all rushing out to buy factory fresh production engines and sticking in modified and special construction frames?
