My M-IV has a Kohler Command 25. I use NAPA brand 10w-30.
Regarding chain adjustment, mine has the adjusters on either side of the center sprocket. It uses a 3/4" wrench. Note: once these adjusters run our of adjustment the chains will need to be changed. It is highly recommended to use good quality chain, like Tsubaki Omega, as an example. Stay away from cheapo chinese chain, they stretch/break easy. Keep the chains lubed regularly. I use white lithium in a spray can.
Enjoy your ride.
