Default what is this?

I picked up a 1985 yam4L40049 a couple months ago and i just was wondering if anyone knew any information about it. I know its a self mixing 2 stroke engine. I get about 55-65 miles per gallon with my weight of 170. max weight is 175. I love rideing this bike and I would appreciate any comments or information on maintenance
