Rodney, 
If you're putting it in an O.S. 1.4, definitely leave the seals in. You'll get 300-500 flights with the seals in. With them out, you'll be lucky to put 5 gallons  through the engine before they're shot!

  Bob, So using an OS 140 EFI bearing, is it advisable to remove the seals?

    Since I use theirs, I get this e-newsletter.  This month's tip;
    <<If your Front engine bearing has two rubber seals you should not remove them. These bearings have their own grease and can help stop oil leaks. If your bearing has two shields, we recommend you remove one of them. For instructions on removing your shields take a look at this Help Section.

    Your Rear engine bearing should be open on both sides to allow as much fuel as possible to pass through and act as a lubricant. You may however want leave one shield on in the rear which would help to protect the rest of the engine from any foreign matter getting through. This should not be done with one seal. If you find your engine is stingy in getting fuel to the rear, you should definitely leave the bearing open.
    In our next issue of the Boca Bearings Tips & Advice Newsletter we will show you how to remove your bearing shields. >>

    Note - if you open your crankcase, using sealed bearings, and the crankshaft counterweight it dry-looking, or the lower part of the bearing isn't pooling oil, you may think about removing the seals.  I do, for this reason.
