1978 Suzuki GS

hello im selling my 1978 clean gs550e bike. this bike has a nice clean seat with no tears and there is only a few dings/nicks threw out the tank and paint. the only visible major rust is on the brackets that hold the windshield on. i just had this bike serviced at blackmans cycle shop which is a suzuki dealer. it has fresh inspection brand new rear tire fresh oil and oil filter new steering neck bearings new vacumm seals and the carbs were also rebuilt. i also had new plugs put in. they also did a tune up and adjustments....bike takes off really fast and shifts very smooth. the bike is ready to ride and is road ready however i had the carbs rebuilt bc you could feel it luggin and it needed it... after they did the carb rebuild it ran fine for a day then it started again its still acting like it wants to stall at stop lights and from time to time the rpms hang high...after talkin around and research im told it might just be a throttle cable binding so that may need to be replaced...sometimes the bike runs fine with no flaws then it seems like it has it bad day unless the carbs arent fully sync right...they said my compression and so forth was great and i have been running 97 in it. you can still ride the bike you just have to give it alittle gas at a redlight so u dont stall... should be an easy fix since i had all the work done. the battery in the bike is weak and should be replaced. i start the bike with the kick start then after the bike is warm it will restart off the battery. i have all my recipets to show the work done to it. any questions feel free to email...the bike is in the driveway if you would like to drive by and look at it 6362 farm bureau road allentown pa 18106 ps there is about 21k on the bike for mileage also i do have the title in hand...this will be pu only no shipping cash is preferred no checks or money orders no warranty and sold as is
