2004 TTR225 crankcase cover 1

[Bamboozle]

Does anyone know where I can find a new crankcase cover 1 for my ttr225?

The part number is 4VW-E5411-01-00

Mine has a hole in it. Everywhere I look says it's unavailable. Is the one on the ttr230 identical? I can find those. 

I'm trying to get my bike prepared for an upcoming trip. Any help would be greatly appreciated.

how bad is it - you might be able to get it welded ?
