Attention Stock Appearing racers....
Starting in 2019 we will have a Stock Appearing class at each of our series races. We tried to run a 4cycle open class but it just didn’t pan out at most tracks. So we are going with an SA engine package that will be much more affordable to the racer to build and race. The engine rules are listed here.
2019 GaUAS Stock Appearing engine rules...
Any Honda GX200, Clone 196cc or Predator 212cc BASED ENGINE

allowed.
Any air filter adapter
Any fuel. Methanol preferred
Must use OEM style crank shaft. “Spot” welding the cam gear is allowed to prevent gear slippage. May interchange cranks to blocks. (Example, May use 212 crank in Honda block)
Maximum bore size is 2.766
Must use OEM style piston. May interchange pistons from one style engine to the other. (Example, May bore Honda block to take a Hemi piston)

We will try our best to be open tire for this class, but some tracks we run at may have a tire rule. If so we will give plenty of notice before a scheduled race.
These rules are not concrete just yet. They may be a change or two before next season starts. We are just getting the word out. Contact Jody at ARC Racing for any questions...
