WTF is JOG?

Re-jetted, no airbox??? Let me guess, 55 pilot and 155 main jets?? If so, you're probably getting 30 mpg. Have you ever checked it?
When I got my bike secondhand, it had those jets with a stock airbox and Dyna muffler. It sounded "cool" but was a turd and spewed wet soot all over my rear brake arm. MPG was in the 30s with my 6'3", 250 lb frame on it and it would barely do 80 mph downhill. The bike also had an air leak at the exhaust header/muffler juncture and popped/backfired a good bit during deceleration and shutdown.
I fixed the exhaust leak and dropped down to near stock jetting (I think one size up on each if I recall). I can short shift the bike as fast as I can work the levers through all five gears in any part of the power band and I'm consistently averaging 50 MPG. It does feel a little flat on top if I try to stretch gears compared to the overly rich setting, but it gets there way faster and gets to 80 mph with ease before it abruptly flattens out. Bike hardly ever pops on deceleration and just a light to medium poof at shutdown.
[RANT] My take on this is that while every bike and environment is different, I believe the common jetting advise on this forum is probably leaning towards too rich. I think people have focused too much on sound instead of focusing on performance and have overlooked other contributing factors.
For example, you say no airbox. Some would assume that means you need to make a jetting adjustment to compensate for the increased air. Not always. If you put a pod filter on there, there is a good chance it's more restrictive than the stock airbox. In addition, it could be covering one of the air passaged at the back of the carb. Or, possibly your bike was already rich and would benefit from being leaner, but you end up going richer instead.
I can't answer those questions for you, but nearly all the advise thrown around here is make it richer and that's just not always true.
Not everything you read on the internet is true. [/end RANT]
Of course, your jetting could be spot on for your needs. Your bike might be running perfectly. I don't know. Just offering up an opinion that may or may not help.
