Crank Journal Bearings 78 750F
« on: October 31, 2012, 08:09:47 AM »
How concerned should I be with Crank Bearings on a a motor with 22k on the clock?

I'm in the process of freshening up the top end:  new valve guides, valve job, new tensioner, rubber/plastic bits, honed jugs and new piston rings.

I wasn't planning on splitting the cases.

What is avg life for the main bearings for a street bike (not raced or abused as far as I know)?

Let me also mention that I can't seem to get the search feature to function or I would be hunting for the answer instead of asking.
