Re: Cowl Baflle
I would put at least some baffling in, even if it were just a plate to the cylinder heads at the bottom of the front cowl opening, and also a good low pressure lip on the extraction point.

Re: Cowl Baflle
its like wearing a seat belt while driving. You don't have to but in the long run it may be a good idea.
 Personally I would put in some type of ducting, it is a way of protecting your investment.

Re: Cowl Baflle
On mine I used the factory supplied bottom piece, and added sides and a top piece as well. All the airflow coming into that opening is hitting the cylinder and being forced through the fins. Call it piece of mind!

Re: Cowl Baflle
Your engine will run some 35+ degrees cooler with four sided cooling baffles.
