From what you've said in other posts, I think you are running super rich. Here watch this video.
You said you wouldn't go back to the stock NT carb in a different thread. Just put it on and see the difference. I got the HP carb a week after I put my first bike together and got it running (which took about a month, mainly from problems I created figuring out what the problem was). After almost two months I realized the HP carb was hurting performance more than helping. Only because of tuning though. You need to play around with jet sizes and find out which jet is PERFECT... you have to buy jets and I never found the right one. I didn't try very hard honestly either. With the NT stock carb you can adjust your fuel air ratio somewhat without rejetting. I live at 4,300 feet so I adjusted mine at the leanest setting and got the best results. Results may vary. But even with my HP carb I can go 30 miles on a tank without running out. My routine was 2 days at 15 miles commute round trip and refill. Never did I think I was close to running out.
There is a sticky on the NT carb in the forum. When I was brand new I read it and it made no sense to me. I'm about four months into the hobby and still learning every day. I reread that NT carb sticky thread again and with experience, I understood a lot more of it and it made me decide to finally remove the HP carb and give the NT a try. Honestly I was amazed. The issue of constantly being super gentle on the throttle to prevent fourstroking made riding the bike almost unenjoyable. Now with the NT back on, fourstroking is gone except for at wide open.
I just trying to encourage you to give that stock carb another try and play with the mixture. I think you'll be satisfied with the results.
