This is the new style "aftermarket" engine cover that protects the engine and enhances the airflow. It is sold at  and is a very well designed piece of aluminum. It did fit almost perfectly. After some small modification at the starter side that is.

The price was high but it lasts and I damaged my original cover more than once, and repairs with aluminum brackets were holding it together.

The two V-shaped chimneys had to be transferred to the new cover. No big deal.

The bolts that hold the cover are 4-5mm bolts that go into a simple clamp nut.
