hey wolbrink471 why don't you read all of the rules before posting your ?'s
12.A. PRODUCTION: ?P?
The same engine must be used that was originally installed in the
specific motorcycle at the time of production. 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.
