Well a funny thing happened today...
Pulled the motor and went to the shop..
Disassembled the motor and after checking found the problem..
They put std std bearings on a 10-10 crank yet labeled the rods and mains 1.7 with blue paint so I wouldn't mess with their clearances..
Humans make mistakes, it's Christmas and I'll let it be...
Holy crap man!!! I've been egging about your build since you got that cover from me. It was the first time I ever had less than stellar performance... Now I guess I know why!! 11.7 thou is kinda loose!!!!
At least you found the problem and it's fairly easy to fix now.
