You can grind down the welds where the flange meets the down tube, this smooths out the gas flow, just cleans things up a bit.
Whether it improves anything much is debatable, if anything it would be at higher RPM, as bigger bores increase gas flow, but for mid to low range you want smaller, same applies to carb bores. From my experience, the Fazer engine without serious mods is pretty much on the money, add a K&N and a good quality end can and you've got a noticeable more usable motor low/mid range.
