Work it baby, work it!!! You might want to run a mix of race fuel. Shaving the stock head that much is a lot and might preignite on pump gas...If you don't ride in any mud, then get the clamp on filters (2)...Your jetting will be too lean w/ the small separate K&N's...Start w/ 330 mains, try different needle positions, adjust air screw, you might need a larger pilot (27.5). Can't get you any certain answers, everyone seems to come up w/ a totally different jetting when it comes to Toomeys.....
You might want to get different reeds to add to your list...
