Iv used other brands, glaxal, goofit and others and tbh they all are the same…a 47mm bbk paired with A-9 Cam is the best bang for your buck…it will take a stock 25-30 mph bike to 45-50+..literally a 50% performance gain..i wouldn’t ride a 50cc gy6 no other wayBest setup for engine:This 80cc bbk#85 main jet in stock carbOpen exhaustA-9 Cam
