Hey eveveryone! Just picked up a relic mid 80's tri moto 125cc. Would like to do a basic oil change . Any idea where the plugs located? Also what is best recommended oil to use I live in ontario canada and the bike has sat idle for about a year . It currently does start and run though.
also what would be the best fuel to mix ratio on this ( colder weather here and bike has been sitting)

Thank you everyone!!
