i have a 1980 gs550l in good shape but im having a problem with the motor sputtering in the top end. it seems like its flooding out when i get into the higher rpms and it just doesnt have any power. it still runs but is just really sluggish. i had the carbs cleaned when i got the bike and it has custom exhaust with straight drag pipes and 12" baffles. it starts and runs good in town unless i try to go full open on the throttle then it starts the sputtering.. any help would be appreciated.
 
Welcome to the site. When you say you "had the carbs cleaned", did you do it yourself or have someone else do the job? Were they fully dipped, orings replaced, and jets properly cleaned? Are you using pods or the stock air box? Did you replace the orings

Basscliff will be along later with the official welcome - read and heed everything in it if you want to have a good running bike.
 
i had them cleaned by a local shop and the orings werent replaced as the shop told me they looked fine i am using the factory airbox rite now but want to replace them with cone filters
 
Take the carbs off the bike and clean them properly according to this article found on Basscliff's site (he'll be along later for the more official welcome).

Then get new orings from www.cycleorings.com to include the intake boots (owner of that site is a member here) and bowl gaskets from Z1. Make sure you do a valve adjustment while you are cleaning the carbs (real easy to do - instructions are also on Basscliff's site) and then synch everything afterwards.

Don't switch to pods until you get it running correctly first as it will take ALOT more work if you change it right now.

Throw your location in your profile and you might find one of us is close enough to help out. Don't be afraid to ask questions but know most anything you need to ask has been answered so diligently use the search feature or Basscliff's site first.

Hi Mr. welder2021,

Yes, the carbs need to be properly cleaned AND they need to be properly jetted for any intake or exhaust modifications.

Now I'm going to dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

thank you for the welcome and i will start cleaning the carbs asap
 
update: as of today the carbs have been dipped and i had one with float post damage i had welded and found out the carbs arent aluminum like i thought they are a cast aluminum with magnesium in them so if u go to weld them u need special rods for your tig welder but now its welded and i am in the process of reassembling them and i am going to go over the wiring before i put the carbs back on.... any suggestions? i have been playing with the idea of doing a cafe project with the bike when im done... im in davenport iowa if anyone is close by too
