Please help me with tuning???

Happy Fathers Day guys... Need a little help. I put in a K&N Filter and a 205 main jet from Factory Pro. I'm 2 1/2 turns out on the A/F screw. I've done the Scar Mod with 2 shims a while back when I had the stock main jet in. I also put in a #58 slow jet a while back too when I drilled about 15 or so 3/8 inch holes in my stock air cleaner. Before I put the 205 main jet and K&N filter the idle sound good and the bike ran strong. Now it idles funny like it's going to cut off. It sounds more like it's panting than a normal idle sound, but it still runs strong in every gear. Slight hesitation before it takes off when I twist the throttle for keep speed at top end. Maybe it's just a bit rich per the smell. Oh yeah...new plugs yesterday Champion RA8HC. That's all the info I can think of giving. I'm open to all ideas and suggestions.
