QMB139 GY650 Big Bore Performance Carburetor

Everything came well packed. Im pushing my 50cc to its limits. 55 so far. I have more polishing to do. Will be using you guys again for parts. My next conversion is electric, but for now im running her till she blows up lol nitrous next. It will take some serious tuning so remember the big bore helps you get more power to the cvt. Thats where the real fun begins. Recomend on 89.5mm variator and 5g to 6.5 with a 788 belt 4.5 to 5.5 for hilly and fat boys likevme 260lbs. If you move up in variator, be sure to check starter clearance. You may need to kick start. Thank you guys for letting an old dog feel young again lol

Fast service matt is awesome took the time to help me understand exactly what I needed. The carburetor is well put together top quality Thank you Rolling wrench!!
