Found a 2010 sf with only 1200 miles all stock

Runs okay but the header is all blued out and i believe its running slightly lean.

From what ive read… leave the 35 pilot. Go to 124/125 main from the 118 and 2 turns out fuel screw?

The oem jets on motosport.com only go up to a 122 main. I know i can find 124/125 on jets r us. But wondering if someone can give me some clear advice.

DFW Tx sea level.

I want to leave the bike all stock but just optimize the jetting and maybe pull the snorkel…
