Another question re: '78 800 inline 4. The wraparound portion of the cover that came with this motor has no plastic sound blanket (and appears nebr to have had one). I have a wraparound cover from an earlier model which has an intact plastic sound blanket. Was the '78 800 supposed to have the blanket? If not, will using one damage the motor in some way? I like the idea of keeping the noise minimized. Thanks again.
