I have a 1983 Suzuki SP 100 Motorcycle and it won't idle, any suggestions?

Question

you have to keep giving it gas to keep it running, I have replaced the oil and filter and i have tried ajusting the idle speed and nothing seems to work please help!

Answer 1

I'd do a minor tune-up, clean or replace the spark plug, clean the air filter and clean the carb.  When cleaning the carb, use an aerisol cleaner that you can spray through each jet and vent to make sure they are clean. If you don't want to take the carb apart use a fuel system cleaner like STP or SeaFoam mixed with your gas.  Another good way to clean things is to use Cheveron or Texaco gas with Techron.  Don't buy the additive its not the same as what is in the gas.
