AMA Statement on Supercross Fuel Ruling

After additional investigation and consideration, AMA Racing officials have concluded that the fuels in question from the January 20, 2007 Anaheim, Calif., round of the Amp’d Mobile AMA Supercross Series were correctly found to be in non-compliance with the 2007 AMA Supercross/Motocross rulebook. Testing has shown that the illegal substance Methyl Butynol is being added to the majority of fuels being used in Supercross.

Because of the apparent widespread use of fuels using this substance in the Supercross paddock, and the fact that AMA Racing and its competitors could not have foreseen these circumstances, the following rule will be waived until April 15, 2007 regarding these fuels in their current configuration and any other fuels using the same illegal substance, so long as they meet all other fuel specifications:

Chapter 4 — Offenses, Penalties, Protests and Appeals; A. General Information; Section 1.each participant agrees to abide by AMA Pro Racing’s rules and procedures. In addition, AMA Pro Racing-licensed riders are held responsible for the actions of their crew members.

Points, purse and trophies of penalized riders, Nicholas Wey and Joshua Hill will be reinstated.

AMA Racing will continue to test race fuel for compliance of fuel rules as stated on Page 10 section L in the AMA Supercross/Motocross rulebook.
