Went from ~48-50mpg to like ~45mpg. I know that isn't much, but one of the reasons I like to take the bike most times is also b/c of the high gas prices. Also a reason to get the misses on the back to ride with instead of taking a car.
Any suggestions on how to fix it? Way to adjust the gas flow to make it better?
Would it get better if I went ahead and debaffled? Or make it worse?

When I drilled my pipes I noticed 4 things. The pipes sounded horrible, like I could hear the air coming out of them, especially when I reved it and let off real quick. The second thing I noticed was my power went to %%%%. Next the smell of fumes, and finally the poor gas mileage. I removed the 1st plate and the baffles and it got a lot better. I removed the mickey and the 3rd plate and its perfect. You gotta get all that junk out of those pipes and let them breath. Fully de-baffled stock pipes have some volume to them but not as loud as the majority of aftermarket pipes I've seen.
