Not to jack the thread, but I took my left side deflector off, per DK's suggestion below:
1. Remove the left side thigh protector. This will help the air flow very fast past the rear cylinder and out the left side...this is good for the engine, and will reduce the amount of felt hot air on the right side.
With the right side shield still in place, it acts like an air scoop pulling air into the space behind the cylinder...but with the left side removed, that air can now exit easily. With both installed, they are essentially two scoops that push air from both sides to collide and swirl, with no real good place for the air to exit.
It is not symmetrical looking, BUT, you can only see one side at a time, so it is unlikely most will notice you have a thigh protector on one side and not the other.
Doing this will cool the engine overall, so while riding & when coming to a stop you have a cooler engine than you would otherwise. However, if you are at a stop long, or in continuous stop & go, you will feel more heat on the left than the right.
