I have the new 26 hp liquid-cooled Kawasaki on my SuperZ. As you're aware, this is the engine which has been laid on its side to eliminate the gearbox (at least I guess that's why they did it). My former SuperZ had the 27 hp liquid-cooled Kawasaki with the gearbox. Do you have any idea why my AOSafety radio headphones have a bunch of interference on the AM stations when cutting with this machine. My old SuperZ didn't have this problem. Not a big deal, but I don't get to hear Rush now. Any ideas or fixes?
