Rotax Carburetor Update from RMCUSA
Due to unforeseen backorders and inventory issues, the Maxspeed Group has decided to postpone the new 2013 Carburetor Technical Regulations until further notice. The purpose of this bulletin is to properly allow all competitors to receive an equal opportunity to be able to order the parts and to be equally able to make the transition from the 2012 Carburetor Rules to the new 2013 Carburetor Rules.
The Maxspeed Group recommends all USRMC series to adopt the new 2013 Technical Rules and Regulations ASAP, but to continue to use the 2012 Carburetor Regulations until supply of the new parts is no longer an issue.
