2004 Yamaha rhino 660
Bought a 2004 Yamaha rhino and 2 wells later the head gasket “blew”. Pretty sure it was already blown but I had that fixed. When I got it back, it started making a grinding/slipping noise when I let off the gas but not hitting the break. It does this for a few seconds and then something catches and noise stops. It doesn’t always do it. Any ideas? Thanks in advance!
