Test drive the Seven L8 this week at Sonoma

Posted on by

motori L8 engine photoThe Motori Seven L8 Jr shifter kart engine is a high-performance, Italian-engineered powerplant designed specifically for developing young racers. This exciting platform offers them the opportunity to train 100% as real KZ drivers.
The inclusion of the 6-speed gearbox from an early age is the fulcrum of this new engine that incorporates all the basic characteristics of a KZ 125 kart engine.

“With all the focus on Jr shifters lately we thought we would introduce a new product to the West Coast that is sure to impress,” tells Challenge of the Americas promotor Andy Seesemann. “The Seven L8 Jr. is a purpose built 80cc KZ style shifter engine with factory paddle shift, and I have one mounted up on a chassis for demo runs. For those wanting to give it a try come by the FTK trailer on the unofficial practice days.”

Designed with the same precision and racing pedigree as the senior L8, the Jr. version features a smaller displacement (80cc) and tuned power delivery to suit junior class drivers, offering a perfect balance of speed, control, and safety. With a six-speed paddle gearbox, liquid cooling, 24mm Dell’Orto VHST carburetor, and 25HP, the L8 Jr. gives young drivers an authentic shifter kart experience while maintaining manageable power levels for developing skills. Want to bridge the gap between Cadets and KZ, this is the motor for you.

K1 Tires, Fuel, Fines

Posted on by

Thank you to everyone that came and raced our inaugural K1 event.  While the circuit does have some challenges from an organizational standpoint, it also has several rules that competitors are required to follow as well.

While some of these rules are unique to K1, they have a few that are pretty consistent with the other facilities we utilize, like Sonoma and Utah Motorsports Campus.  
 
Used tires and fuel cans are not to be left on the property.  They cannot be left in your spot when you leave, near a trash receptacle, nor hidden in the bottom of one.  
 
I am sure that everyone understands these rules, but to place emphasis on how serious K1 ownership is on this issue, we published these rules in several places on our website, sent an email prior to the event with the rules listed and finally, had a box to check that you understood and agreed to comply with these rules when you registered on the website.

YOU AGREED TO  THIS

WHEN YOU CLICKED HERE

Unfortunately, with all of these reminders, announcements and consent agreements in place, some of our competitors chose to break the rules.  
 
More than 30 empty pails of fuel and almost 20 sets of tires were left at K1.

MORE THAN 30 FUEL PAILS AND ALMOST 20 SETS OF TIRES WERE LEFT BEHIND AT K1

 
The facility rules highlight a $150 fine per occurrence if this happens.  With more than 100 items left at the track, this fine can be pretty large.
 
It is sad that some in our community fully understand the expectations, yet choose to not follow them.  
 
One of the more disappointing things was the fact there there were a couple of VP cans, an Aspen can and Hoosier and Evinco tires mixed in with the Sunoco Supreme cans and Shinko tires that were left behind. 
 
This means that some competitors chose the Challenge as the event that they were going to dispose of all of their trash from the 2 or 3 weeks they were at K1.  
 
After 20 plus years of organizing fair and professional events, 18 with the Challenge, I thought that I had earned a level of respect greater than this, but I guess I was wrong.  
 
Therefore, to hopefully remedy this situation moving forward, we will monitor it at Sonoma, where we cannot leave these items as well. 
 
If any items are left behind at Sonoma, pitspace fees will increase by $50 each to $150 for the Utah event to cover any fines or increased costs.  If any items are left at Utah, this increase will be permanent.  
 
Regards,
 
Andy
