I just finished plastigauging my b18a1 crank assembly using King Alecular main bearings (pretty much a standard set) and came out with #'s 1, 2, and 4 with 0.025mm (or 0.001"), #5 came up at 0.028mm, and #3 at 0.028mm. Most of the time I just match the honda number/letter combos and order stock bearings, but this time I just couldn't afford the dealer's price tag. They're a bit tighter than I usually build my motors, and honestly I've never had one come up this tight before. Should I even bother to run with these clearances, or change them all out for a larger spec?
According to my Honda service manual, #'s 1,2,4, and 5 should be 0.024-0.042mm, and #3 0.030-0.048mm.
I don't want to risk spinning a bearing as soon as I start it up...what would you do?
