engine cases

Does anyone know if 05 yz450 case halfs will interchange with an 06.A friend busted the chain side,and found that side on ebay.But it looks like an 04-05 even though it is listed as an 06.It has the clutch actuator arm mounted like an 04-05.But if it will work he will save more than enough to change those parts.

nope there different ,on the 06s they rotated the cylinder back a few degrees to centralize the engine mass . but there are prob even more diff than that.

They're not even close. Cylinder angle, internal oil tank, wider across the trans, no external oil lines, etc., etc.....

thanks for the info
