Default Main bearing clearence? ACL too tight

The ACL bearings comes out a little tighter than 1 thousand of an inch on all the mains on my motor. Which bearings to get?

Looking at this: https://honda-tech.com/zerothread?id=715490 it seems to me that if I chose "pink" bearings instead, I would get around 0.6 thousands more clearence than the ACLs (If the ACLs really are the same as OEM greens). Just wanted to know if that is correct before ordering new bearings. Thanks.

Thanks for the link.
If your motor needs green bearings the ACLs will be fine I have read.
This is a good read: http://forums.evans-tuning.com...light
You can also see which clearences are acceptable in that link.

Back to my question...

If you are getting a bit tighter than 0.0010 say 0.0008-0.0009"--try the HX race bearings--they are 0.001" looser so your clearances will be around 0.0018"-0.0019"--which is good. the ACL Hx

I guess I'll try out the ACL race then. Same clearences after "precrushing".
