Actually, this is very one I purchased BEFORE I found out the stock carb was unserviceable:



"Performance race CVK quality 30mm carburetor for the 152QMI and 157QMJ gy6 125 and 150cc four stroke chinese scooter/atv engines. Fits, but is not limited to the Roketa, Sym, Tank, VIP, Tank, Sunl, Vento, etc." - as sold on www.scrappydogscooters.com/125_150cc_Performance.html

Should I get a smaller one? (I read that a smaller inlet increase the intake velocity?)

Hellooo from Miami, FL!

I ride a GY6 150cc myself and have learned plenty along the way. Best wishes!

Hi ITR,
It's been a bumpy couple of months, finally brought Akagi to a mechanic referred from a trusted friend. Took a couple of weeks and few trips back and forth, but the bike is back in front of my driveway. Drove it about 10-12 miles back from Miramar in the rain, with a dead battery. It's crazy, but the guys there had trouble too getting the motor to start and stay on running. So, they spliced a red wire from the positive end of the starter solenoid and cut the ground (black) wire to the coil. I simply connected them to a 2 way switch at the side panel vent and now have to engage the starter in a 3rd sequence.





The mechanic also adjusted the carb to handle the increase of air intake from a custom setup he crafted from the aftermarket filter and the stock airbox hose. It looks pretty legit in my opinion, but he says that balancing the A/F now is much more trickier. I even considered modifying the downpipe with a A/F sensor bung, maybe someday...



The bike has run a few dozen miles since, until one morning it decided not to turn over before the effects of passing tropical storm Harvey rained out an entire week. So it sat for a few days. I'm in it again, dialed the carb back and starting all over with the A/F mix. There's a idle adjust and screw at the drain bowl that controls the flow of gas into the housing of the carb. Once I get it firing, then I dial back the A/F until it starts to sputter, then turn the idle screw higher RPM until it sounds smooth, but its like chasing a ghost without knowing whats really working right. The carb sounds like its flooding every time I give it throttle (about 30-50%) then bogs out. It was the very problem that had me consider selling this whole damn thing and moving on to something else.

I had to make the run to the mechanic again to pick up the parts I had left behind; an oil coolers system (the mechanic replaced the oil the Hialean mechanic filled with Royal Purple now.), a crate of odds and ends, the old stock air box, and random hose bolts and clamps. I made the trip back with little stops. The vaccuum lines to the petcock keep slipping from the loop on the manifold, so it will choke without fuel after a few miles then relink it only to pet the throttle due to some hesitation. I think the motor is mad fuel thirsty because it runs a heavy vaccuum now.

Whats up ITR?

Thank you for the feedback!
