Without some sort of baffle breaking-up the reversion wave you lose much of your low end torque. Bigger jets will not improve your mileage.

It is a well-matched combination of intake and exhaust and jet sizes and carb settings that make for a good running machine. Lot's of good information at nightrider.com.

Removing your baffles = better sound & loss of low-mid range torque.
Re-jetting should not be necessary unless you change to a high flow A/C.
