A (1-9) immediately below applies to new and old style engines.
1) All engines are to be production based front mounted four cylinder, four cycle motor motorcycle engines.
2) All engines must be self starting by means of a starter motor. In the event of a broken starter the pit steward will be notified so a push start can be arranged and that the track officials are aware of the problem should the need arrise on the track. Starter must be repaired by next race date.
3) Engine center line may have an offset of 6 inches from center line chassis.
4) Maximum C. C. 1205.
5) No turbo chargers, super chargers or nitrous oxide
B (6-9)
6) Stock head configuration (porting allowed)
7) After market carburetors, fuel injection, headers and iginition systems allowed.
8) Crankshaft, rods, pistons, are at builder's desecration.
9)
Transmissions, 3rd, 4th, 5th and 6th gears may be removed.
Marcus Wicks 2006 GSXR 1000cc has been grandfathered in.
C (1-5) Applies to 1200cc
1)No porting or polishing
2) Crank, Rods, Cams, Boar, Stroke and pistons must stay stock.
3)All gears must stay in as stock
4) Headers, injection and power commander can be changed or added.
5)Bore and stroke check and seal will be done under owners cost.
Note careful consideration should be used when building an older engine in the reference to cost. The older engines will require a substantial money investment in order to obtain the horse power equal to the newer generation engines.
Newer generation engines come stock from the factory with 160 plus horse power. These engines can be purchased as a car kit engine and come completely race ready. Our goal is to have a competitive race club at the minimal cost to each car owner or driver .
Note the Dyno is presently being tested and until the tests are fina1ized and accepted by the majority vote of the Western Outlaws. These rules will govern.
