Maxton Motorcycle engine class question

["Dale" <dmirror@prodigy.net>]

Why are Maxton motorcycle engine classes "refined" to have a /4 or /2 tag?
My question is does Muroc  and El Mirage, for that matter, the other courses
don't have the same derivation.
It seems, my 1000 cc /2 (twin) doesn't fit the pushrod class and I don't see
an existing  P/P 1000/2 class.
Where would I fit?
Thanks !
