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.
