I don't see where Kawasaki-Thailand tightened it to "spec", it was like they ran the gun wide open, went and had coffee, and then came back and released the trigger.
My air compressor would not crack mine loose. I ended up putting it all back together, & riding to a chum's place with a bigger compressor. Still, that one would not pop it loose. We had given up. I had two impact sockets that size, one standard and deep-well. We had been using the deep-well, and I was afraid we were going to break it or strip it out.
Before we hung it up, I tried the short socket on it, let it hammer awhile, and then it reluctantly let loose. OMG.
