He had a great day learning the new kart, the track and getting the feel for going fast in his new ride. Welcome to karting Max! We are looking forward to many more days like this to come.

Kartspeed had another fun weekend at Sonoma. We started out with Friday practice and finished up with ROK Sonoma racing on Sunday. Greg came out and put on a quite a show in VLR Masters. In the second Heat, Greg had some terrific battles all race long! Lots of back and forth, passing and re-passing with Joe O’Brien. A few off-track excursion,s but he finished the race in a strong 9th place. Everyone came away with smiles making it a successful race weekend at the track.
We all missed Freddie Jr and Sr…both missed this weekends race due to coming down with COVID just a few days before the event. Get well soon!

Another great customer track day at Kinsmen Kart Track! Great customers, great track and a beautiful day!

Hi All,

ROK FEST Race Recap:
In Micro ROK we had Franco Morales and Benjamin Monroy (For those that don’t know Benjamin, he is a Croc Promotion driver from Southern California).
Qualifying: Benjamin qualified in P-1 with a blistering 58.35 and Franco qualified P-4 with a 59.85.
In the first heat, Benjamin scored the win with Franco finishing P-8. In the second heat, Benjamin again scored the win with Franco running a very strong P-3! The third heat saw Benjamin in P-1 and Franco finishing P-4. The final just clarified that Benjamin was the fast guy today, winning with a big margin. Franco with a lot less experience, but a lot of determination, drove really well and finished on the podium (P-2) for the main! So super big congratulations to both drivers and support crew.

In Mini ROK Freddie Guzman Jr was about to run his first ROK Fest event. With dad/tuner Freddie Sr spinning the wrenches and making the adjustments, they qualified a solid P-5 at a 58.44. Pole time was a scant .4 quicker at a 58.062 with only a tenth between each driver.
Heat one went great until a technical penalty (Broken Battery Zip Tie) relegated Freddie to the back of the grid. Heat 2 saw Freddie push hard to get back up to P-6. Heat three saw him move up one more place to P-5. Another penalty pushed Freddie down to P-6 in the Super Heat, but his lap times were very competitive so there was hope for a stronger finish in the main. Unfortunately, a slower driver that made it impossible to pass, regulated Freddie to P-6 in the main. Not a bad finish for their first ROK Fest weekend and the experience will give them a solid direction for testing in the coming weeks.

Racing is fun as long as you put in the work, and all the drivers mentioned above test rigorously and thus make constant improvements. Test Hard, Race Easy. Test easy and the race is hard.

Until Next Time
Jeff

Everyone please send good vibes to Freddie Jr for his first ROK Fest Race at Sonoma this weekend!

ROK Sonoma Rd 1 Pro Shifter: With two drivers entering the shifter race this weekend, we were all excited to see how things went. Pro Shifter class racing this year at Sonoma has a mix of Vortex ROK engines and full race KZ powerplants.

Colin McGrath returned to racing after a year off. A former ROK GP Champion at Sonoma Raceway, Colin knows his way around the track and showed that even with 12 months off, he can still wheel a kart with the best! Running in a tight pack of drivers running 4th-6th during the first heat race, Colin showed he was not about to drive around casually to get back into the swing of things. In heat two Colin ran as high as 3rd place amongst some seriously fast shifter drivers >WAY TO GO COLIN!

We were watching Colin in the main, hoping for some more excitement, but the field spread out a bit more compared to the second heat race….and became a bit of a procession. But Colin stuck his sword in the sand this weekend showing the other drivers he is out for P-1. I, for one, can’t wait to see how Colin progresses this year in his shifter kart.

Yung Ko was our second Shifter driver this weekend. After 6-8 months of hard work practicing and testing, Yung was eager to find out where all that work put him in a tough field of shifter drivers. I was happy to see him hang in there all weekend and push to get faster and better. Which he did! With some more seat time this year, I hope to see Yung pressing the mid pack drivers and looking towards the front of the grid.

ROK Sonoma Rd 1-VLR Masters. Greg Cromwell jumped back in the seat of his 100cc kart and drove hard in both heat races, building confidence for a hard charge in the main event. Sadly, Greg didn’t even manage to make it through turn one. Another driver spun directly in front of Greg leaving him no place to go. Running over the other kart, Greg flew through the air and bounced back down to earth with an axle bending thud.(The video above) Sore ribs and a sad face were the result. On to the next race….
