  1. The GX motors had really weak pressed tin rocker arms that 'folded' at the pivot. I found main reason was that plant fitters using them on generators, pumps and other industrial equipment were trying to run old cast iron side valve type valve clearances (0.008" to 0.016") instead of almost zero valve clearance (I set them same as motorcycle valves, 0.002" to 0.003" as I had run motorcycle dealer workshops until I found industrial equipment paid far far better) There were 32 non running GX engines at the place I worked, (UK Plant) when managing director visited I was introduced as 'The Honda Expert'

  2. I started in a Honda/Yamaha dealers in 1978, first time I've ever heard of the Honda Wankel motor
