How do you tighten chain on 1995 suzuki lt80?

There should be 4 bolts on the back between the brakes and the sprocket, the top two will have slots that should be of equal distance once finished.
Loosen all 4 bolts then take the jam nut loose at the chain tension bolt This bolt should be on the same side as the sprocket and chain. Turn the tension bolt clockwise until the chain has about 1 1/2" of slack in it. Tighten everything back up and you should be good.
