 Some people have done so and claimed "no problems"

But the facts are that it isn't a good idea if you want max cooling for your 
engine. If the factory thought they weren't necessary they would have left 
them off. It cost the factory to include these baffles.

Here's what I know. The cyl heads are in need of more cooling than the cyls. 
So the baffles force most of the air to go thru the heads, and not around the 
cyls (by blocking some of the airflow around the cyls). In addition without 
the baffles the bottoms of the cyls don't get much, if any cooling, air, and 
thus can overheat while the rest of the cyls get overcooled. This is because the 
baffles force the air around the cyls and over the bottoms too. Without the 
baffles, the cyls now get cooled unevenly and may distort their shape which will 
affect ring sealing.
