Does the Yamaha have switch to shut off idle control? In identical conditions, I tried new Yamaha 2400 from power sports dealer and said i'd buy it if it ran my pancake air compressor. It wouldn't. My used Honda 2000 would. I would empty all air psi from tank, have to switch from idle (eco) mode to full rpm on Honda, and instantly ( while throttle opened up and rpm ramping up) turn on the compressor switch and less than 75' F Honda would run compressor. The Yamaha 2400 wouldn't. I feel 2 reasons, Yamaha was brand new and no breakin time (maybe stronger after loosened up) and no eco (idle) off switch I could use to ramp up rpm immediately before I turned on air compressor switch. Conclusion new Yamaha 2400 wouldn't run it and my used Honda 2000 would. Identical conditions. Salesman walked away impressed with Honda. They sell both brands. He had nothing to lose.
