anyone else who has installed a Sugino 75 crank and BB have really tight clearance between the left crank arm and BB? the left crank arm has maybe a 2 - 3 mm gap before the BB cup. its not impeding the rotation though. did i over torque my cranks or nothing to worry about?

You must measure the side of a right and left crank (side of pedal hole) from the center of the frame.
The plus or minus 1mm is a proper size from the center of the frame to the center of chainring by 42mm.
(This is NJS standard formula)
It is not abnormal if the error margin of a right and left size is within 2mm.
Because it is a translation of PC, my English is not accurate. However, you will understand the meaning.
1 - Clearance is just that. Clearance. Doesn't matter if it's an inch or a foot.
2 - I sincerly doubt you could over torque the cranks and push them to far down the spindle. They'd split before that happened.
