Unfortunately, once you deviated from factory jetting and filters, finding a solution will be trial and error. I would definitely remove the plugs and turn the pilot screws out 2 1/2-3 turns, and remove every single part of the air injection system. since you no longer have an airbox, you won't have to plug the hole in that, but you will need to cap the unused vacuum fitting on the rear carb. You will need to cap the reed valve covers on both heads, you can get coasters for this purpose, or you can do what I did, and use the original covers, with rubber caps on them. The caps I used were from Autozone, and were designed to plug heater hose fittings on cars. They fit the bike perfectly, and cost $1.99 for 2.
