This thing runs perfect first kick. I just cleaned the carb and changed the oil and filters for good measure. Everything works as it should. oil pump and reservoir working perfectly. no leaks. no drips. will do 76 mph and gets 63 mpg. great vintage two stroke legendary Yamaha single 5 speed. Id ride it anywhere. 1975 Yamaha dt175b with 1200 original miles and family owned for three decades.
