Regarding the use of “old style” Yamaha cylinders at the Reno Region 11 IKF Race . Please refer to the 2010 IKF Rulebook…Section 617.21 and Section 207 “Note for exhaust restricted Yamaha classes.”  This means that if you run an old style cylinder you will have to add 20 Lbs and put a red stripe on the outboard side of the cylinder. The Yamaha classes are exhaust restricted.”
