If you spun a rod bearing, you need to measure the connecting rod, and crankshaft journal with a micrometer, and dial bore guage, or equivalent. If anything is out of spec, it will need to be resized, or replaced. The crankshaft will need to be micro polished. If you do not micro polish a crankshaft properly even though it is within factory specifications, it may cause premature bearing falure. If you know what the sizes of your connecting rod, and crankshaft rod journal are, there should be a factory size chart somewhere for the proper bearings. Motorcycle honda parts department has this too. You can always double check your work with a plastiguage, and buy one or two new bearings if needed.
