The conrod has broken and smashed the case. And the broken part thrown to transmission area, and made some gears broken too.
Now, we try to find a full engine and buy the case too so we have spare engine. We need 3 weeks for get the case. Thanks dor your attention. Wish Japan go well.
Ninda, source and adapt a more common engine such as a Yamaha or Honda 450!
Chasing orphan engines and parts is a fruitless task.
