It's not much to go on, but your 2nd picture it looks like #1 is lean and #3 is rich. You mentioned the idle being high. Start looking for air leaks. And for sure, replace the petcock.
Mad
I've thought it was like a cylinder turning on but honestly I've never checked for leaks on the bike I've replaced those intake boot o-rings and a good amount of the airbox hose clamps but like I said never checked!
I say cylinder because when it rises in idle it turns more so into a complete drone but with a faulty petcock I cant base it off anything i guess.
And the bike hasn't yet been finely tuned for the exhaust, it does have a stock airbox but this exhaust is pretty loud and open. The mains are 1 size up and that is where the power is GREAT but like any inline 4 cylinder peak horsepower is where it's always at
