Rule Clarifications and Upcoming Rule Changes: Honda cylinders, SKUSA TAG classes and IAME/X30
Friday, 19 September 2014 17:54

Honda Cylinders:

Many of the previous complaints regarding the 01/02 cylinders have subsided – as builders, tuners, and drivers have learned to deal with the differences in these cylinders. At this time, SKUSA is not planning on making any changes to the current rule structure for these engines/cylinders.

SKUSA TAG classes:

  • TAG Junior: This class will continue to be a Leopard engine only thru 2015. For 2016, the class will become an X30 engine only.
  • TAG Senior and TaG Master: Effective October 18, 2014 (30 days from this notice), the X30 engine weight will be reduced to 365 lbs in TaG Senior and 392 lbs in TaG Master. This will be the final weight adjustment for 2014.
    • A new X30 PDF published on the SKUSA website today, September 19, reflects the addition of carbon fiber reeds, along with a change of the minimum reed thickness to .010”. Only IAME reeds are allowed.
    • For 2015, both the Leopard and X30 engines will be allowed, and drivers will be able to switch between both engines without penalty. As previously announced, both the ROK TT and Motori 7 will be removed from the list of allowable engines in the SKUSA program starting in 2015.
    • For 2016, only the X30 engine will be allowed in these 2 classes.

Additional X30 information:

  • All X30 engines used in SKUSA competition must be purchased from an Authorized IAME USA Dealer. IAME USA is developing an Identity Card that will be supplied with each new engine, as well as making them available for engines previously purchased in North America. This should not cause any problems for legitimately-purchased USA engines, and will allow IAME USA and its customers to conform to the stringent EPA regulations regarding off-road competition engines.
  • Pricing on replacement parts for the Triton carburetors has reached an unacceptable level. IAME USA will be announcing a program that will replace all Triton carburetors on qualifying engines with a Tillotson carburetor at no cost to the competitor.
  • Both the new ID card and carburetor will be announced when available – targeted for the beginning of 2015 from your local IAME USA dealer.
Rocky Mountain ProKart Challenge Finale Set for Grand Junction
Monday, 25 August 2014 16:24
This year’s Rocky Mountain ProKart Challenge is nearing its end, as the series’ final two rounds are set to take place over the Labor Day weekend. The Colorado- and Utah-supported Superkarts! USA region has enjoyed a year of great racing, despite less than favorable entry counts. Following two fun and unique weekends of racing, the series will see its final race outing take place at the popular Grand Junction Motor Speedway on August 29-31. The challenging 9/10 of a mile long track was the site of the series’ opening weekend back in May, and it will cap the year as well. Championships are still up in the air in several classes, and the racing is expected to be worthy of the championship weekend.

The premiere class of the RMPKC through 2014 has been the S2 Semi-Pro Stock Moto category. A cornerstone on the Pro Tour, as well as at SKUSA’s many PKC regional events, the S2 class always supplies great racing and close finishes. This has definitely been the case this year in Colorado. Tase Flores enters the final weekend holding a 130-point lead over Myles Marolt, and he’s definitely in the driver’s seat. The opening rounds saw Lindsay Brewer score her first ever SKUSA victory at GJMS, and she will be back to compete in the final weekend, sitting only 30 markers behind Marolt. Ryan Rudolph made up for his opening two rounds of the season – which were plagued by mechanical issues – by doubling up his wins at rounds three and four in Calhan.
Rocky Mountain PKC is returning to Grand Junction for Rounds 5 and 6 on August 29-31! The Online Store is now open for Pre-Entry!

SKUSA Competitor Bulletin: IAME X30 Weight Adjusted for TaG Senior and TaG Master
Monday, 16 June 2014 16:11
Superkarts! USA would like to announce the reduction of the minimum weight for those competitors utilizing the IAME X30 engine in TaG Senior and TaG Master. After considerable evaluation, testing, and input from our competitors, it has been decided to adjust the weights to the following:
  • TaG Senior: 370 lbs
  • TaG Master: 400 lbs
As per SKUSA rules, these weights will take effect 30 days from this posting – with July 17, 2014 as the day the new weight structure begins. Superkarts! USA intends to continue monitoring the relative competitiveness and will make additional adjustments as necessary.


After last Friday’s announcement of the host hotels for the upcoming Superkarts! USA Pro Tour SummerNationals at the Modesto Grand Prix on August 1-3, the reserved block of rooms at the DoubleTree have already been sold out. Superkarts! USA is urging competitors to call and make their reservations at one of the other two locations as soon as possible: SpringHill Suites by Marriott Modesto and Days Inn by Wyndham Modesto. More information on these locations can be found at the SKUSA Hotel Information Page
