02 660 with proflow adaptor and foam UNI. Big Gun slip on. Mains are at 175_180 clip on 4th, Ran great. Then when from a big gun slip on to the full Yoshi and was lean mid range. So clip was moved to richest position. Runs good but feel like it's a little too much fuel for my mods. Anyone else had to fatten up their 660s so much?

Get some small, very thin washers to go under the needle to be half between lean and rich.

Yes - you are using stock needle aren't you?

Switch to DJ needles, drop your jets to Mikuni 160, 165 (DJ 148, 150) and all will be good again!
