There is a round sight glass on the right side of the motor down low, near the front - you'll probably have to get on your hands and knees to see it. The bike must be held up vertically (not on the side stand) so you'll need someone to hold the bike up. It should also be level front to back and the oil level should be at about the halfway point between the top and bottom of the glass. Oil type recommended by Yamaha is SAE20W40. The site www.venturerider.org is a good resource for information on the Royal Star bikes. Be sure not to use automobile oil as most of those have "energy conserving" additives that will quickly ruin your clutch!! Stay with motorcycle specific oils to be on the safe side.

There's a glass window on the right side of the crankcase marked for high (max) and low (min) levels. Get on hands and knees, have somebody hold the bike upright, and look under the front crankcase cover directly beside the right operator's footrest; you'll probably need a flashlight to read it.

Four, but you'll have part of a quart left over. The capacity of the crankcase is stated to be 3.5 (US) quarts without filter, 3.7 with filter change. The clutch and transmission are lubricated/cooled by the same oil, so I'd recommend a new filter at every oil change.

remove radiator cap slowly pour in 50/50 mixture while burping radiator hose. Better to do while running if possible

your switch has gotten water in it, under the tumblers the connecters have been arking & caroading causing it to loose connection
