Don't bother, the NT is not in the same league as the Bofeng is a larger MM size as regards it's threads as well as overall physical size and the NT is smaller thread size, it will never look the same size just by eye balling it because of the physical size of the outer portion.I have an NT jet set. I should pull the BoFeng jet and compare the size of the hole to the sizes of the jet set I have.
Hello again Sir, how you doing? I have the same frame as you and I have a question! Can you please send me a link to the disc brakes you have? Have a good one and thank you for your time Sir!!The BoFengs come stock with the #70 jet...I am assuming your at a 3000 ft altitude thereabouts and that your needle valve C clip is at the second notch to the TOP of the needle??? If so, Move it up to the very top notch and see what happens.
One thing I have different on my BoFeng than you do is a much better, non restrictive airfilter that is a no fuss direct replacement for those stock ones...Less restriction, more air, is much better to run at altitude.

You can see it on my motor here below, I'm at 4500 ft.
Gasoline makes all the difference in the world too...I use Ethanol-Free gas which burns and powers much better than the regular gas that now has 15% ethanol.

I'll do you better than that...Here is the tutorial I wrote sometime back that has links to most everything I used on my bike including the mags and disk brakes that actually came with the mags since you need the 160mm disk rotor for the front and the 203mm rotor for the rear so it can clear the 36 tooth sprocket that also comes with the mag wheels...If your gonna use a bigger sprocket you gonna have major problems trying to fit a disk caliper onto the rotor because the chain and sprocket will be in the way.Hello again Sir, how you doing?
