    My 89 Low Rider requires a quart of oil every 300 miles. It has good compression(160 psi) on both cylinders and the plugs are not fouled. It does not smoke from the exhaust, so I don't see how it could be burning this much oil. There are only a small few drops on the ground where I park it. Any ideas about where this oil could be going?

    Could be LEAKING bigger time when running..

    Follow the leak (s) and tell us Where they end up or come from.

    ALSO, check the primary level ???

    IF Too full... engine oil being pushed there.. EVO's can do that. Out of the engine primary seal at the crank.

    The compression looks good, but have you done a leak down test on the cyls.?

    If this is an early EVO case, they had a problem leaking out into the primary
