ok long story short i got a 1980 yamaha chappy (lb50pg). it has 4050 miles on the thing so i put a polini 70cc kit on it. the carb is shot so why not just get a aftermarket one. i look and ive read to get a phbg carb. at treatland i can get a 19mm intake that fits the moped but i cant find a phbg carb with a cable choke that is 19mm. I can get a 21mm phbg carb with a cable choke but cant get a intake to fit well atleast i cant find. and im planning on getting a ninja pipe and change the powerband with 4 petals. so i need to find a carb and intake.
