Rebuilding the bottom end

[tonkota]

I am wondering about rebuilding the bottom end of a 2F while replacing the piston rings.

Should I:

Just put in new bearings?
have the crank turned and then new bearings?
Check the clearance with plastiguage and leave it alone if with in spec?

Am I right that the bearings are designed to ware, not the crank?

I would check everything. If it looks pretty good call it good.

Without pulling the tranny you can't get the crank out.

look at the bearings to see if there's any unusual wear then have the crank ground, if not i would just re-ring with bearings
