I used plasti guage to check my main bearing oil clearances
Factory specs call for: .0007-.0014 and from what I could tell on the plasti guage it was .0014 and .0015. I couldn't tell.

Even if it was on .0014 I am kinda worried that the clearances are not tight enough. Should I be worried or keep pushing forward.

Thanks guys,
Chris

The crank was just polished there was no grooves journals were fine. These are the same color ,green, honda bearings that I took out of it.

I'm with-in service limit (.002) if that means anything.

Thanks

do what you want, the info is there. i don't mess around with second guesses when it comes to engine work. idk about you, but i can't afford to start an engine just to pull it apart cause i guessed it was "ok". its all up to you.

my opinion i myt add..

oem spec's are meant for 7500rpm max..

ive personally seen .0020 .0025 clearances, but then again they wer revving to 10.5k

i always thought.. tighter = longevity
looser = performance
the balance can be had thru experience or good guidance..

ur numbers are ok for most builds..

i wouldnt worry

That's exactly what my research has shown, and that's why I'll be running a .002 stock service limit on mine. I'll be reving upwards of 8200 with supporting valvetrain of course and a shimmed oil pump...
