Getting ready to dump in trash

At the very least, you can use the attachment feature (the paper clip icon when you're composing) to post one, and only one, picture per post. You can also link to images that are available over the dub-dub-interwebs, and most people post to some 3rd-party site and link in. Then you're not limited to one and people don't actually have to click on the image to see it. BassCliff wrote up a little doc on doing that and put it on his web site:

In the absence of a 3rd-party site, you can also post pics to albums in your profile here and link to those pictures. It keeps it all on the GSR.

I can't really visualize what you're speaking of. Maybe someone else can though.

Ok so these are the openings i was reffering to and are now closed, unless you guys say otherwise.

Chuck here are the needles. The one on the left is the old one.

I dont see how those new needles could work properly . Compared to the old ones seems like it would be either starved or flooded . just my 2 cents

vacuum sync holes without plugs equals no go.. if that's what they are?? not too sure but can't wait to hear more input

I don't see how they will ever work either . go get the correct parts!

Greetings and Salutations!!

Hi Mr. myown550,

Sorry if I'm late with this. It contains just about everything you need to get your bike running safely and reliably. It's the "mega-welcome".

I'm not quite sure what that threaded hole is on your carb body but I'm pretty sure it's not supposed to be open. Can you pull back a little? That needle for the needle valve assembly doesn't look right either.

If you are here you probably have a 30 year old motorcycle that needs about 20 years worth of maintenance. You'll find all kinds of helpful tips, procedures, manuals, diagrams, "how-to" guides, etc, in the links below. Let's get started.

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,

I can't see my #4 from that angle with tank still on and all, but yes, my #3 carb has that same threaded hole. Empty. Runs fine. Same year/model. Doubt that plugging it can either help or hurt.

That much longer a needle seems like it would definitely cause lean running. I say "seems" because of course if the seat were machined with the longer needle in mind and they were replaced as a set it could be a wash. Did you measure the float heights on reassembly?

[myown550]

Ok guys quick update,
I plugged those holes on the carbs, i rechecked and set the float heights to spec i called dealer to confirm the needles they sold me are correct and he says they are, ok so i installed carbs back in i put the lid on airbox, put gas tank back on and this is where i stopped for a min! Since my prime on my petcock is not working i did it manually so i dont have to crank the engine, ok that being said while im syphoning on the vacuum line i started tasting fuel? So i figured something is wrong with the petcock i dont think fuel is supposed to come out from there? Ok i pulled the petcock out and the diaphragm had a small hole pinched in. I replaced it with another used one i had laying around from another bike i had in the past, i put the tank back full choke and she fired up but only for 5 seconds. Same thing the second time she ran only for 5 seconds and then i couldnt start it again. This was the longest she's ran since she started giving me crap. Guys am i in need of a new petcock? Thanks

[mike_of_bbg]

Yes, bad. No fuel in vacuum line.

[mike_of_bbg]

Just grabbed one of my replaced needles and looked at your pic. The new one definitely looks wrong (length vs. width) but the perspective of the old one looks correct. The measurement on my old one is ~17.25mm just touching, not compressing, the spring. Did you get new seats with the needle? Like I said if the needles and seats were replaced as a set maybe the seats were re-designed to work with the longer needles. The needles don't look like they're available OEM as a separate part: only with the seat.

Oddly enough - and it's kind of hard to tell in that pic you posted of the needles - but I see what looks like a lip on the new one, but not on the old one. If the old needle was bad I'd expect to see a lip on that one, not the new one. It's likely that if you replaced the needles due to overflow issues, that the petcock vacuum line was actually the source of your overflow.

Did you replace all of the needles?

[myown550]

Hi,
Yes I forgot to mention the new needles came with the seats. The one thing I never put back on is those little washer looking things that go around the seats and keep the needle from coming out. Those actually grew legs and walked away I could not find them but the bike ran without them. Man this thing is stressing me out, I also just ordered a new kit for petcock.

Have you tried a gravity bottle directly to the carbs and bypassing the tank? Be sure to plug the vacuum port on the carb. also, what condition are the lines in..any holes in them??? New intake boot orings and they arent pinched ?

Hi Chuck,
i have not tried pouring gas directly into the line yet, the boots are brand new with o-rings, the fuel line is new and so is the vac hose.
