    Complain to them and ask for a new motor.
    Sometimes they will send you a new replacement, but you still have to pay for shipping the defective motor back to them.
    Too many nightmare stories about SBT.

    Is the crankcase OK?
    I would think softer aluminum case get damaged/shaved more than the steel crank...

    The rods rubbed counterweights. Rings probably broke in great with the iron lapping compound.
