Hey Guys...I have the same yamoto 150 ATV as FMAN. Well at least it appears the same from the photos that he posted. Recently my nephew broke 3 teeth off of one of the gears inside the trans gear box...more specifically the main gear with 17 teeth right next to the cover. I've been searching for a while for parts and nothing but dead end leads...please post your links to yamoto part suppliers...thanks a ton!!!
