A bit filthy, but a 1973 Kawasaki 350 Bighorn. A little bit modified.

By request, I'm going to try to get this back to engines by deleting the OT motorcycle riding comments. But bring on the bike engines! I'll post some of the great Honda 250 6 if I can find them.. I tried to leave the bike posts that seemed about the engine, not the bike, but may have messed up a couple.
