When I bought this I torqued the cover down too much and cracked the cover. But Boyesen replaced the cover under warranty and no charge. This was for my 2009 KX250F it seems very durable and it does have an oil fill hole unlike the pictures also remember to torque the cover to only 6 foot pounds.

First off, Hinson has the best quality products I have used. My mechanic tells me that without changing to products like this one, you might as well just trash your quad. These provide the needed cooling for your quad. Top quality and great fit for my KFX 450R.
