For the most part it's probably in the ball park, but quite possibly a bit small. What other mods have you done? What kind of air temps will you be running in. To give you an idea, I have my mods and jetting listed in my sig, jetted for sea level with about 60-65 degree temps.

I was running a 290 main with your set up but then again I'm 400 feet above sea level, so you should be right on.

Interesting. I'm running smaller mains (310) but bigger pilots (32.5) and I ride at about sea level. I don't know how many turns the air screws are adjusted, and I'm running at least 1 Alba needle (as a result of my friend and I tweaking one when reinstalling )

 

It's a bit of a smoker, but runs fine otherwise. Would it be better to up the mains and drop the pilots on mine (it's stock internally, just a K&N & no airbox lid, PC pipes)?

That does sound really big on your pilot; I would probably drop that back. I was running a 27.5, with 1.75 turns out on the air screw, but switched back to the stock pilot (25) with .5 turns out on the air screw and noticed much improved throttle response. Also, if you're running one aftermarket needle, it may be hard to get your midrange jetted properly, because likely the aftermarket needle is a different design than the stock needle. As far as the main is concerned, the primary difference is because you still have the airbox with the lid removed. I have completely eliminated the airbox, running a Toomey (Uni) 2:1 filter assembly, which will flow a decent amount more air than an airbox with the lid removed, ie. bigger main.
