THREADS ARE GONE !! IS THEIR A EASY FIX ? WHAT WOULD IT COST TO HAVE FIXED AT YS PERFORMANCE ? BOUGHT THIS MOTOR USED RUND GOOD ON TOP BUT IS A LITTLE SLUGISH ON BOTTOM END . ANY INFO WOULD BE GREAT .

THANKS DAN

The only way to tell is to send the engine to our service dept for a look. If the cost to fix is too high, we can make you a good offer on a replacement.
