07 engine case

So my buddy discovered a crack in his 07 yz450f right side engine case. Iv got another friend that has a 2006 yfz(quad)450 and has a complete bottom end assembly for it that i could have for free. Does any one know if the cases will match up? Im pretty sure the internals are different...gears, flywheel, crank...but all i need is the one case half.

If you mean the right crankcase half, no, the quad won't work.  The hard points for mounting are different. 


The right side crankcase cover that encloses the clutch and primary gears will fit.

Yea thats wat i was talkin about. Dang. Alright thanks for the info
