Whats up Dude..

I had a similiar setup,Im also at sea level,

My air box lid was off..

310 main

middle position on needle

stock pilot- 25

 

And shee was pretty crisp..

Every shee is different though, keep playing with it, you'll get it right...

good luck

Around here....500 to 800 ft above sea level, normal riding temps...60 to 80 degrees, with an airbox and the lid on, 310 or 320 is too much main...but as said, every bike is different.

I'd say you're almost spot on, if not a little rich... Piped bikes I've worked on with NO lid on a K&N Filter I ended up with a 270 to 290 main.

 

Here's how you dial your main in. You can't be too far off....
