2005 yz450f

Hi there, new to the thread. I bought an 05 yz450F about 6 months ago and life was great. I let a friend borrow it and it came back with a hole in the crankcase (right side) and inner clutch cover.

Upon further investigation it looks like the kick start gear broke loose and cracked the inner clutch cover and right side crankcase.

What is the best course of action for me?

I could buy a new motor- not happening
I know i could find a donor motor (risk)
I could buy a new crankcase and inner clutch cover which would be a lot of work but the cheapest and probably the way i would want to go even though it would be a lot of work.

The motor still actually runs, it just spits oil out so im pretty sure the internals are good. I would also need to replace kickstart gear.

any input/advice? Or does anyone on here have a motor to sell?

I appreciate anything!

I would find the parts on Ebay or craigslist and fix it.
