The tolerances are ALWAYS the same. You must mean the thickness of the bearing? So, if you're crank is "smaller" than standard "green" bearing size, then you use a thicker bearing, giving the same Oil clearance/tolerance with each bearing. I think max is .02mm max clearance on B-series.
I would have said just use OEM Honda parts to start with...
I recently replaced my crank and all main & connecting rod bearings...
I used OEM Honda bearings with the correct codes. I also plastigauged them (should be done anyway) just to make sure my clearances were ok.
Everything checked out just fine.
Get the right colors from Honda and plastigauge them to be sure.
Thanks for the reply, i have ordered some plasti gauge.
I also have the bearings removed from that crank and standard rods.
When im using the plasti gauge, do i install it with the bearings? when i install it with the bearings, how do i measure its the correct thickness and that the tolerance is correct? vernier caliper?
