    New Stock Appearing class for 2019, GaUAS

    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 didnít 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

    Must use the OEM style carb. Can be bored to any size with NO EPOXY showing on the outside.

    NO GX390 or any other Big Block Carbs
    allowed.

    Any air filter adapter

    Any fuel. Methanol preferred

    Must use OEM style crank shaft. ďSpotĒ 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)

    May fly cut piston for valve relief.

    Any Rod that uses an OEM size wrist pin

    Must use OEM style head. Head does not have to match block used. (Example you can use a Hemi head on a Honda block) No Welding on outside of head. Chamber welding OK

    Any head gasket

    Porting OK

    Max Valve size 27mm intake, 25mm exhaust

    May use Stainless valves

    Any retainers

    Any spring

    Any push rod

    Any cam

    Any flat tappet lifters

    Any rockers

    Any Header

    Must use a RLV-4106 Mod Muffler

    May use valve cover extender for rocker clearance

    No Billet Heads

    No block welding. Block repair of rod damage OK

    No deck extensions

    Bolt on block braces OK

    Billet sidecover OK

    Any top plate

    Any pulse operated fuel pump

    Any chain guard

    Any clutch

    Must use an SFI approved Billet flywheel. No OEM Cast flywheels allowed.

    Must use OEM style ignition. No PVL ignitions or MSD ignitions allowed.

    May use electric starter box

    Any fasteners and/or studs allowed.

    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...

    Sounds good, any chance of getting some of the 100cc 2 smokes in on that plenty sitting on the bench around here. Kent ran that limited outlaw deal around Nc&Sc and it drew more than UAS. Chuck.

    Not in this class. This is for a 4 cycle based class. Lots of these engines sitting around ready to go in this area, 100cc 2smokes not so much. Got to go with what is popular at the time.

    Yea, bummer that there's no animal engines allowed -- easily fit in the CC window and certainly plentiful used animals on the cheap.

    Taking a SWAG here, this animal issue might be with the OEM carburetor.
    I don't know how much an OEM clone carb can bored without hitting air, but they do start out at .615 or so
    Likewise, I don't know how much an animal carb can be enlarged without hitting air, but I do know that the animal OEM carb starts out with a significantly larger cross area.

    As "Limited" as these "Stock Appearing" rules are ÖÖÖ.

    Allow the Animal with the Huaya or Ruixing Clone Carb...Ö..easy fix...Ö.and you could sell off that Walbro PZ or Briggs Copy PZ and finance a decent chunk of the mods.
