Heres the deal. My newphew was riding his 450 and the chain slipped. It broke off the chain guard, and case saver. When it broke this off, it broke the bolt and the case where the upper bolt goes. Now the case is broken where the clutch pivot shaft is. The shaft is exposed and leaks transmission oil. Cant find the piece that broke off.

How to repair:
1. Buy a new case
2. JB Weld the the hole and cover it with the JB Weld, to keep the oil from comming out.

He does not have the money to get a new case, any other suggestions.
