I have an 83 GL 1100 that has been sitting for about 3 years. It starts but idles poorly. Must leave choke engaged all of the time to keep her going. would like to make her ridable before spring. any help is appreciated.
I would suggest that you remove the carbs and give them a complete cleaning. There is plenty of info on this site to guide you through the process. Old gas gels and hardens and as a result blocks the carb jets. You should also make certain that the fuel tank is clean as of course replace the gas and air filter........Carb removal and cleaning is not that difficult if you are somewhat mechanical but is is time consuming and has to be precise. Do one carb at a time so that you dont mix parts. Dont use any wire or drill bits etc. to clean the jets.....instead use a good quality cleaner and compressed air. Make certain that everything is spotless and be sure to be accurate with the float and pilot screw settings.......after the carbs are clean and back on you will have to do a carb sync........GM
Also if the bike has been idle for a long period of time you should replace the timing belts, all fluids etc. Check everything before you ride right down to the valve stems which rot with time.......the 1100's are tough and reliable and with a little TLC you will have a nice bike. Good luck GM
