    the camera angle makes my head hurt. don't go for cool here.

    looks like a typical hipster dipshit build is what i think xb is trying to say, but don't hold me to it.

    specifically, does it do it while riding, or just when you rev it up. what carbs, filters, jets, etc. we need more help to help you.

    are all the exhaust joins sealed?

    I'll give you a hint; you have fuel and air mix combusting at the wrong time or in the wrong place she ain't suppose to make pops and exploding sounds outside of the 4 sealed combustion chambers.

    Step one, figure out exactly where the sound is coming from, one cylinder or all of them, inside the exhaust system or inside the intake system.
    Are there any indications if you examine all four spark plugs together? Are you seeing any signs of blow by at either the valves or the piston rings? Oil consumption or combustion leakage around the cylinder head? Soot accumulation inside your cheap shit pod filters? Oil and crud spewing from your crankcase venting lol does it even have crankcase venting?

    lets all take a guess at what it is based solely on his video, hopefully he will share the outcome once he figures it out; I vote one or more intake valve is fuk'd.

    Solution: Put way too much theft insurance on it then park it someplace where somebody will steel it strictly for the front forks and wheels that don't really belong to it. Should not take long because I'm sure it has no steering lock, that was probably eliminated with a large hammer and a steel punch.
