no acceleration,starts hard,need help
Bike starts hard and bogs on accelbcleaned carb,good spark etc...
How old is the gas in the tank ?
is it ready mixed or does the oil pump work (is the oil tank full?)
if the gas is older - change it, use the ready mixed one.
I had the same problem, turns out the exhaust was plugged.
the previous owner was running with oil in oil tank AND premixed fuel creating quite a carbon deposit in the exhaust and oil. Cleaned it with a wire coat hanger and burned out the rest.
Could be that you are running super rich on your fuel/air mixture. Try leaning it out.
You shoulddefinitely adjust the idle and air mixture screws if your FA50's not running well. Take a look at the carburetor diagram and make sure that the air mixture screw is 1 3/4 turns, as instructed, and that the idle screw is adjusted properly.
Honestly, I wasn't able to figure out how to set the idle to "1500 +/- 150 RPM," so I just ran the bike until warm and then adjusted the screw until it "sounded right" -- whatever sounded like it should be going at.
Also, make sure that the choke cable is completely off when running the bike, and especially while adjusting the idle / air mixture screws.
you might want to check the compression. it should be between 100 to 125. if its low rebuild is in its future.
Make sure your transmission oil is clean if the acceleration is bad after you adjust the mixture. You'll be amazed how much this can slow you down.
If it smells rich you may want to change the spark plugs. Easy to do and should be done before mucking around with carby mixture. If you have had bad fuel your spark plugs suffer.
What is the trannys fluid? And recommend oil? Any 2 stoke oil?
