Box Stock class, this message is update you as to the new carburetor rule. As it was communicated to you at our pre event meeting at the last December race on 12/17/16, that instead or replacing the existing Mikuni VM26 with the sealed Subaru carburetor, we will install a new program begging on February 4th, where you must run a track assigned Mikuni VM26 stock Carburetor.

Here is what you can expect upon arrival.

1. At registration, you will need to buy in to the new carburetor program at the rate of $75 for the remainder of the season or #25 per race.

2. You then will be assigned and given a carburetor for that event/race night.

3. The carburetor will include, air filter adapter, manifold rubber hose/boot and one clamp that secures the hose/boot to the carburetor. (You may not alter or replace any of these items).

4. You will install the assigned carburetor directly to the manifold sealed on to the motor. No additional extensions allowed. You may apply additional external bracing to better secure the carburetor if you need to.

5. You will connect your throttle cable on the slide and your air filter on to the air filter adapter. No modification of these items allowed.

6. At the end of your nights event, B main or A main, you must stop at the impound area just outside the exit door and surrender the carburetor to our track tech. Please have tools on hand at this time as you will have to disconnect your throttle cable, take off your air filter and take the carburetor off of kart and off you go.

7. Failing to observe these directions could result in complete disqualification for the race/event.

Please be advised, make sure to be early on February 4th, to ensure adequate time for this instillation to take place properly.

sealed Subaru motor program nationwide.

The following rule will be placed into effect by this rule bulletin during the 2016/2017 racing season and will be incorporated in to the 2017/2018 Rule Book.

This change will be put into effect following the last December race on 12-17-2016 and must be completed prior to the first scheduled race at the Lakeport indoor on January 13, 2017. Also, upon returning back to RBO for the 2nd half of the 2016/2017 winter series.

  • The details of the new carburetor package will be in place and on display early November 2016 along with the parts needed and associated costs.
  • The new application will use the OEM carburetor as used in the beginner box stock class and will be sealed as part of the engine assembly.
  • If you own an OEM carburetor, you can apply it to your retrofit once it has been inspected by an authorized builder.
  • To save time, you may submit your carburetor for inspection at any time. Contact your builder for more information.
