Karts at Adobe Mountain Speedway 2024


Once again we’ll be racing on Saturday nights, Donald Curtis will be running the Karts for Kids divisions, Daniel Strickler will be promoting the Champ Karts  and AMS will be in charge of the AZ Predator 212’s and the AZ Outlaws.   We currently have a 10 race championship: Feb 24, Mar 9, Mar 23, May 4, May 11, Sep 21, Oct 5, Oct 19 (at Verde Valley),  Nov 2, Nov 16 (year end banquet with an afternoon start)  


The First AMS Kart Race of 2024 is coming up this Saturday!   We have added the SuperStock classes, Published Payouts,  Awards presentations, Victory Laps, On- Track Winner Interviews, 90 minutes of practice, and Championship points (and yes, we have a 10 race Championship Scheduled).   The weather is looking great for Saturday, Gates open at 12:00 pm, Quick Driver’s meeting at 2:15, Hit the track at 2:30.  We’ll continuously cycle similar groups until 4:15 PM.   From 3:00 to 4:45 we’ll be doing race registration ($10 pill), with a “Race” Driver’s meeting at 5:00 and Heats 5:30 to 6:30.   Bikes will do their heats from 6:30 to 7:30 and then the Karts will be back with Mains from 7:30 to 8:30.   After each main, the driver will take a victory lap and stop at the podium for a quick interview and pictures.   After all the Mains are finished we’ll invite all the spectators into the Kart Pits and do the awards and payouts and more pictures and maybe some more interviews!  


Kart Race/Practice/Repair/Build Day Saturday Feb 24!

If you have a kart that’s been sitting in the garage for quite a while, this is your chance to bring it to Adobe, freshen it up, fix it, or even build it.   We’ll have several mechanics, spare parts, tools, wheels, tires, chains, sprockets,  and maybe even a few engines, to get that old tired kart back on the track! 

If you just bought a kart, or have an unsealed kart that doesn’t quite fit into super stock, bring it! We’ll help with any safety related items and make sure it’s able to compete.  

If you’ve never raced a dirt kart before, we’ll have a 90 Minute practice session to learn the ropes.  

If you don't have a kart, but have dirt track racing experience, then there may be some extra seats available  (send an email to and we'll put you in touch with some owners)

There are some changes in the Kart classes for 2024, we are adding Jr Superstock, Superstock Light and Superstock Heavy.  (thanks to Randy Ricketts and Doug Armstrong at Verde Valley Raceway for allowing us to use their Superstock engine rules).   Here’s the breakdown:

212 Sealed  (age 14+ 365 min wt, )

212 Superstock Light Adult (age 15+ 300 min wt) 

212 Superstock Heavy Adult (age 15+ 365 min wt) 

212 Open (age 16+)

We are dropping the Unsealed class for 2024 as the Superstock engine rules have proven to be very successful at other tracks. 

AZ Boxstock Outlaw (Age 6-12, B&S LO206 Black slide)

Karts for Kids Novice - (Age 6 - 12) Donald Curtis

Karts for Kids Expert - (Age 6 - 12) Donald Curtis

Karts for Kids Jr Superstock (Age 13 - 14, 265 min wt)  

Champ Karts - Daniel Strickler

(Any age exceptions must be approved by the promoter and the track) 

An assistant race director / tech guy will be hired for the 2024 Kart Race Season - Doug Armstong  

We will be doing safety checks and issuing stickers (same as Verde Valley) 

(nuts and bolts wired,pinned, double nutted or nylocked, snap rings on end of front spindles, weights properly secured, stuff like that) 

This year we’ll be doing all trophies and other awards in the pits after all the kart mains are complete (and karts finish weighing).   Spectators will be invited to make their way to the pits to watch, cheer, and take pictures.   

Note on the change from Unsealed to Superstock:  The intent on going with Superstock is to replicate the success they've had with it up in Verde. In an ideal world, this would have clicked sometime last year and the new rules would have been announced much sooner. Because of the late notice, we'll have a grace period for folks who have built karts to the unsealed rules. It will be on a case by case basis and will extend as long as needed. So if you have an unsealed kart, bring it! You will be able to race! Doug Armstrong will be at every race with advice and assistance on bringing karts into compliance with the new rules. We are back on Saturday's at Adobe, let's make this a fun and competitive year!
