I got a suzuki fa 50. I am fixing it up to use it as a daily driver. And It has a big time running problem that I just cannot figure out. The bike starts on the first kick. The engine runs and idles smooth however when your taking off from a stop it doesnt like any gas at all. From what I can gather it seems like its getting way too much air at idle. When you give it gas it stalls on the spot, the only way i can get it going is if I keep flicking the throttle rapidly (sometimes can take me 15 seconds to even start rolling on the thing.) Stock everything, plug chops come out light tan. Sounds about right at top speed 29 mph. The other problem I was getting was it revs...like right around 15 mph when you let off the gas. The engine speed doesnt drop it stays exactly the same as if you didnt let off the gas. The cylinder gaskets are new, so I know the air isnt leaking from the cylinder. I think its a carb problem now but I just need help in the right way. The only other thing that may have a slight impact on this is the plug is two numbers colder then the original one.
