32:1 oil mix, find the longest steep grade around and go wide open up it a couple of times. if the rings aren't seated after 5 minutes of that then you've got one hell of a lemon. only lawyers suggest a soft break in, engineers will tell you to run it like hell. do you think any sane person might sell something like a hayabusa to someone and then tell them to take their brand new unfamiliar widowmaker and take it WFO anywhere? conveniently, one major requirement of being an engineer is losing your mind, so we can wholeheartedly recommend things that would make lawyers cry.
