!980 GS 1000G Carb rebuild money pit

[JBROWE]

Looking for some help. I have a 1980 GS 1000G that I have had for 4 years. I love the bike and the ride. I have ridden the bike many miles and even road from Ky to Minnisota and back. I got the bike in a trade and know very little about it. Last year I started to have prob.s with the floats and gas leaking. This spring I found a shop that worked on the older bikes and the owner has a small colection of older bikes. I took it to him and ask him to look into the carbs. First it was the charging system then the tail lights then he changed the oil. After all of that he took a look at the carbs. He found that the last owner made a epoxy repair to the float tower where he got rough and broke it off. After time the gas un did the repair and let the float loose. He found a doner carb for $150 and started to clean and repair. After 3 months I forced him to give me my bike back and when I road it, I only road it down the street and back. I payed him way more than we talked of and I went home. That night I road one hour hard to a ballgame. Then back home. The first three miles it ran ok. Not as good as befor but ok. I stoped for a light and had to slip the clutch just to get through the light. Sounded like it was way to rich. After some in town driving I was able to open her up to 65 70 mph.She ran rough and had a random hesitation at 45 to 50 mph. 30 min later in the next town same thing at the light. On the way home way after dark I was pulling to the house and it died. I found a fuse bad and replaced it. The next ride same thing. strong pick up cold then miss when hot in the mid range. From 55 to 80 it has strong power. I took the stock filter off to look and they had cut a pice of card board and closed off the whole bottom of the filter. I took the filter out and took a test ride and the bike runs a lot better but still has a dead spot in the mid range. I know he did some thing to the jets but not sure what. If I had to do it all over again I would have bought a 4 carb sink and did it my self. The bike has a stock filter but has a 4 to 1 vance hines pipe. every thing else is stock. I dont mind to spend the money to fix it just dont want to through money at something that wont fix the prob. Anyone have an idea of a good starting place to get me back riding?

Learn to fix the carburetors yourself.

I rebuild carbs but you've already spent enough.

After 4 years you should know plenty about it- time to get serious. Lots of newcomers approach carb problems totally perplexed, but manage to solve them. You could always deal with someone here who could inspect your set and give you an honest answer; worst case, get another set off ebay and start over. If you like the bike, and it's otherwise in good shape, fix the carbs and enjoy happy motoring.

Working on carbs is not a big deal to me just dont know the right jets for what I have. Also time is hard to come by in my little world. I am going to make some time to fix them right and also do some polishing on all the alum.

Your story sounds like mine in the beginning. Long story short, you will learn how to go through the bike and do all the necessary steps to have a safe, reliable ride that will put a grin on your face every time you ride. You are most certainly at the right place!-----AND, you'll save a ton of cash in the process.

I'm willing to bet that the hesitation you speak of is due to old intake O-Rings. They are like $1 a piece and I can't exaggerate the difference that replacing them makes. Start there.

Next, adjust your carb mix screws. Tighten them all the way, and then back them out 2 full turns. Do this for each carb. This will ensure that you are running close to the right A/F ratio. Do not attempt this before replacing the O-Rings!!!

Be careful how you say this. "Tightening them all the way" will lead to breaking the tips off and lead to very bad things. Turning them until lightly seated is the correct way and then backing them out. I'd suggest 3 FULL (360 degree) turns out so you don't have too many issues (I did with mine and it started right up).

Thanks for making that clearer.
