I just went through this over the last few days. I have a stock 2000 banshee, with TORS, Stock carbs and emgine, FMF gnarlys with Turbine core II spark arrestors, and a twin air filter. I put 260 mains in it and left everything else alone. With the lid and snorkel on, it was too rich. I pulled the lid and it runs like it should. I would say that I'm close but not perfect since I needed to pull the lid and snorkel. I'm at 2140 feet in western PA. it was about 75-78 degrees yesterday when I ran it.

 

I am by no means an expert on this and you might seriously want to consider what the other guys on here say. I'm just sharing my experience with a similar situation. Hope you get it tuned soon. Mine really came alive after jetting it "properly" (still need to tweak it a bit)

Everyones bike is different but I am at sea level and 310 mains produced a nice plug chop for me. I kept the pilot the same and currently have stock clip position, but its running a little lean in the mid range so Im going to go down another notch.

 

Just slap in some mains.. ride it and tinker with it. when you finally think you have it right do a plug chop.
