I just put my bike back together after getting my starter rebuilt, when i tried to start it all it did was spin the starter but it didnt turn my bike over. so i took my primary cover off and saw that my jackshaft bolt came out. so i put it back in and with my primary cover off i hit the starter button again and once again it just spun the jackshaft bolt right back out... whats going on? i tightened it pretty tight. dont understand why they designed it that the starter spins the opposite direction that the bolt threads in. it keeps unscrewing itself
