I do not think any of us has said that the GO's are far superior to anything. We just like the motors and just like anything made, nothing is perfect. At least Racefactor is nice enough to take care of the problems unlike OS which told all 4 people by me to BUY a new piston and sleeve and it will solve the problem. Of course it will..... but why did it happen in the first place and now I have about 450.00 into a motor with less than a gallon. You like your motors and we like ours, there is nothing wrong about that. Also Picco's have carb issues, I guess there junk too right?
