I've done a bit of searching and can't seem to find a definitive answer.
What are the clearance tolerances for the mains and big end bearings?

Not sure what they are off the top of my head but I found them by looking in the bearing manufacturers catalogue if that helps!

Cheers guys.

Where did you get your figures from Paul?

I've worked out these from the King racing website:
Big end 0.025 / 0.056
Mains 0.037 / 0.075
