So. I checked my bearings with plastigauge and if clearence is bigger than 0.08mm on connecting rods and crankshaft bearing should be replaced and my crankshaft clearence is 0.050-0.063mm but how i know what is next side of bearing? is it stock= 36.000-36.008 and if clearence is bigger than 0.08 next side 36.008-36.016m? And does the connecting rod bearing selection goes same like the crankshaft bearing selection?
Sorry bad english
The bearings can be determined 2 ways:
First way is: try to see what color of paint is on the edge(s) of the present bearings. It is faint, but will be a color like Yellow, Green, Brown, or Black. Then get bearings one size smaller.
Second way is: find the markings (letters) on the crankcase (bottom side, usually on the front lip of the engine case) and then find the corresponding numbers on the crankshaft weights (sometimes these are very faint, but are etched with a stamp or a buzzer-engraver). The bearings were originally selected via these letters (sizes A, B, C, or D), so you can select the next size smaller ones from there, too.
Even if the engine was worst-case, though, the difference between the 4 bearing sizes is only 0.0004" (0.01mm) per step size, or 0.0012" (0.04mm) for the entire range of bearings. Since these engines like having tight bearings, I sometimes purposefully select too-tight bearings myself, then break in the engine carefully, to help them develop more power. If the bearing clearance is as little as 0.0004" (0.01mm) it will be hard to start the first time, but after that it will always enjoy high oil pressures, and will be very smooth! I just did this with my own CB750, setting the clearance to 0.0006"-0.0008" across all crank and rods. It is VERY smooth, and develops considerably more midrange power than before I rebuilt it.
