New Member and Novice Seeking Advice

[Zen and Awesome]

Hey All,


I hear this is the place to go for info, so here I am. Like I said, I'm a new member and a novice to scooters, especially performance upgrades.



Just bought a 50cc BOOM Mean Dogg II Trike scooter, link:

Plans are to upgrade performance immediately, then drop it, stretch it, reinforce the frame, pull stock appearance parts and go bare bones minimalist style with it. The visuals aren't the problem, my lack of knowledge regarding performance parts is.



Can anyone confirm engine specs on it? I'm pretty sure its a 139QMB, but I'm looking for specific stock measurements for carb, intake, and exhaust fitment.


I'd also appreciate specific performance part upgrade links or any recommendations. Thanks in advance and live awesome.

I would not make engine mods until it is properly broken in. Nothing wrong with gathering performance info now. Probably the first performance upgrade is to de-,restrict the engine. Google it.
