Hi All, My brother and I went to our mom's house this weekend and decided to roll out his old 1972 Yahama Enduro motorcycle. It hadn't been started in at least 10 years. Fortunately the gas tank had been drained so the carb we pretty clean. Anyway, with a carb cleaning, fresh gas, new spark plug and new oil, it actually started up after 20 cranks or so. So now the questions. We drained the oil out of the two drain plugs, but noticed that there is a resovoir below the seat on the left side with a view window. That did not drain, so does anyone know what that oil is for and how do you drain it? Next the foam part of the airfilter disintegrated, so I would need a new one of those, plus it burned oil pretty bad so I need a new top end, any ideas where I could get a new air filter and/or top end? Any help is appreciated.
