i as wondering if anyone knows where i can get either a used crankcase or a new crankcase, cuz i busted the left side case where the shift shaft enters the case when the chani came off. if anyone can help thanks a bunch

 

Ouch I have seen people use JB weld and it hold but I dint know how bad yours is busted. You may want to look on ebay or z400 central. When you get it repaired I would put a case saver on its cheap insurance.

 

it had a case saver on it, but the case saver didnt go that far back just pretty much protected the outer crankcase cover. thanks for the help
