Crankcase crack - does it matter?


I am hobby driver from Finland and some year backs also did some amateur racing. I have -2008 DS upgraded for racing around 2011--2012 (Houser, Elka Stage 5, Hinson, Cheese....etc.), and it has been running well after that...(only issues is decompression, but I can live with that)

Finally had my first crankcase crack in my -2008 DS due to chain pile-up and stuck between swing-arm and front sprocket, due to wearing of chain slider and loose chain e.g.

Anyhow just wondering does it matter? It feel pretty stiff even after the crack, so wondering if must be repaired or the motor mounting is otherwise strong enough to keep sprocket aligned etc...

I have attached few photos to explain.

Thanks for feedback, since I need to evaluate to find 2011+ quad or fix this one.
