proposed 2018 weight rules

Postby Joey Guyon » Fri Jan 12, 2018 12:17 pm

Hi All,

I wanted to get the ball rolling on weight regs for the shifters in 2018. Please let me know your feedback:

After dynoing engines this winter and driving on track this year I have a suggestion as to how to add some weight breaks for the local races

KZ 405lbs: this would apply to the 2 most recent homologations 2013-2015 and 2016 to current (stamp on the engine would say expiry 21 or expiry 24. On my dyno these engines are 44-45hp

Vortex ROK shifter / TM KZ10ES / IAME X30 shifter or KZ/ICC engine with expiry 18 and prior 395lbs: these are "hobby" engines derived from their KZ counterparts. They are de-tuned on the cylinder side of things to increase durability and make them easier to tune. On my dyno these engines are 39-41hp

Motocross engines 380bls: pick your model, these guys need some help locally. I sped up a lot on a KZ10 ES vs my moto at Northstar.

Sounds reasonable to me. There has to be some levelling of the playing field if we want the shifter class to continue to maintain a decent number of competitors. Otherwise, perfectly good equipment will sit un-raced because it is deemed uncompetitive.

I would go one step further and create a list of motor brands/models and what weights they would fall under to avoid any confusion. Also, to help with the writing of the Supp. Regs. From there, each competitor could have identification on their kart steering fairing to show the corresponding weight they are running to help the Scale House Tech person.

I can cut some vinyl letters of a specific size/colour for people to put on their fairings.....
