I cut the threads completely off to get a good look at it. It has almost 3 hours of ride time. Thanks

Looks rich to me. Read this thread about doing plug chops:

That 3 hour plug looks lean on the pilot to me and maybe even lean on the needle. Rich on the main. You can usually hear a lean needle with some pinging when you get back on the gas at mid throttle / mid rpm. Or steady 1/2 throttle cruising the bike will sound terrible.
For the main jet plug chop if you only have a short distance do a 1-3rd gear full throttle pass, pull in the clutch but don’t kill the engine. Turn around and do it again this time pulling in the clutch and killing the engine. I don’t believe in the rule of only one pass or you’ll distort the reading. You can 3 or 4 passes as long as you’re not rolling off the throttle or riding mid throttle. You’re either wide open or idling while you turn around and wide open again. 4 passes on a brand new plug 1st - 3rd gear doesn’t take much space and will give you a good reading on the main jet.
