    Low to no Power 4th gear and above

    I have a "78" GS 550 and it was starting to run better (so I thought) after doing the points and syncing the carbs among a lot of other things. The bike had been sitting for about a year or more... Went to get on the freeway yesterday and kaplat, it had no power, could barely go 45 miles an hour... Rides decent in 1-3 after it gets warmed up. Planning to clean the carbs today any other thoughts on this one?

      Even MORE precisely..."it sat for a year" and the old fuel has gunked up every little passage in them. Sorry to give this advice, but i would do the full tear down and soak to get them free or the gunk again.

      NEVER SNEAK UP ON A SLEEPING DOG..NOT EVEN YOUR OWN.


      I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

          What chuck said. You can not clean them up in one day, they have to soak in carb cleaner to get all the varnished up gunk out of the passages. Carb cleaner and compressed air will not do it. While you are waiting, you will have time to check the valves and order O-rings. http://www.cycleorings.com/

            Greetings and Salutations!!

            Hi Mr. rbecker,

            Has the intake or exhaust been modified?

            Make sure the fuel system is clean, tank, carbs, petcock, etc. You will find the proper cleaning/rebuilding procedures on my little website. Go through the maintenance lists in your "mega-welcome" and make sure everything has been serviced, repaired, cleaned, replaced, adjusted, etc, properly. Shortcuts lead to frustrations. You have a 30 year old motorcycle that probably needs 20 years worth of maintenance.

            So let me dump a TON of information on you and share some GS lovin'.

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

            If there's anything you'd like to know about the Suzuki GS model bikes, and most others actually, you've come to the right place. There's a lot of knowledge and experience here in the community. Come on in and let me say "HOoooowwwDY!"....

            Here is your very own magical, mystical, mythical, mind-expanding "mega-welcome". Please take notice of the "Top 10 Common Issues", "Top 15 Tips For GS Happiness", the Carb Cleanup Series, and the Stator Papers. All of these tasks must be addressed in order to have a safe, reliable machine. This is what NOT to do: Top 10 Newbie Mistakes. Now let me roll out the welcome mat for you...



            Please click here for your mega-welcome, chock full of tips, suggestions, links to vendors, and other information. Then feel free to visit my little BikeCliff website where I've been collecting the wisdom of this generous community. Don't forget, we like pictures! Not you, your bike!

            Thanks for joining us. Keep us informed.

            Thank you for your indulgence,

            BassCliff
