Everything pre-3 min mark is exactly what my GS500E is doing! Thanks for explaining it. I thought it might be something to do with the throttle, but I had a check and made sure it wasn't catching. I'll see how the gasket idea goes.
Edward Miller asked about the tiny O ring that fell out at the start of the video. If you look at 57:00 minutes, you can see an O ring in a small hole beside the screw hole of the right hand carb, and the left hand carb has not got one. That's where the O ring fell out of. On the plastic cover that you are screwing on is what looks like a pen cap/top that covers the O ring. When i replaced the needle on my right side carb, i found the O ring on the engine casing and did not know where it came from. Luckily i only had one carb top off, so i could carefully take the left side carb apart and found where the O ring had to go. The pen caps/tops are rubber caps that are removed to put a manometer on the carbs for synchronising the vacuum. BTW excellent tutorial in real time that will certainly help me now, as i have to remove my carbs for cleaning. (That was the whole point of watching your very helpful video) Thank you for sharing your knowledge with us.
Hi Edward! Thank you so much for pointing out this o-ring "issue". I've been looking for place it goes since May this year. I disassembled my Mikuni BST 33 carbs on Aprilia Pegaso. They look similar to these ones on the video, but don't know Mikuni model on Suzuki. Just to be sure 100% where this tiny o-ring goes, could you please check if this is part nr. 14 on the scheme here? www.bikebandit.com/oem-parts/2000-suzuki-gs500e/o/m22351#sch246853
Also I am curious why that tiny o-ring fell out after the plastic o-ring or cap was removed from the needle and the o-ring fell out together with the needle while turning upside down.
Aleksandr Melanich Hello Aleksandr, I had a quick look at the link you left me, and 14 is the small black O-ring I talked about.The needle has a small whitish ring that is a spacer/washer (it's nylon/plastic). The black rubber O-ring (14) may have been stuck in place from the pressure of being squashed in place, and just fell out after being released to expande. I hope this makes sense to you, and good luck with the rebuild. :-) PS. Please let me know if i have helped in any way.
The needles in my carbs are exactly the same as the ones you have shown. My right one had worn thin and snapped in half (left one was still perfect, work that out. I thought they would wear out at the same time). My local Suzuki dealer (John's of Romford. In Romford, Essex, England.) just looked up the frame number off my bike and ordered some new ones for me, that are the exact same ones again with the C clip and nylon washer. My GS 500 E is my commuter bike, 5 days a week. The picture is my Triumph Thunderbird 900 for cruising with my wife. I have only watched 27:20 so far and i think you are giving some good tips, and clear instructions. So now i am going to watch the rest of the video. TY.
The cleaner is the size of a paint can, you can buy it at most autoparts stores. To put each carburetor in you have to completely disassemble the carbs. And make note of where all of the springs and screws went that are between the carbs. There might be seals or o-rings that you will notice when removing the parts to disassemble it. The idle air adjustor screw needs to be removed. I'm not sure what else on the gs500 needs to be removed that is rubber. Just disassemble it completely to be safe.
I took that diaphragm side back apart and checked everything out, it was good. I put it back together and it dropped slowly. Not sure why. Maybe the cap wasn't sealing well and it sealed better the second time I tightened it back.
you can either get new manifolds (between the carbs and the engine), or take yours off and cover them in silicone gasket maker. Also put some on the side that seals against the engine.
Did you ever take the emulsion/bleed tune that the main jet threads into out? Some bikes it falls out of. Some need a push with a pencil and these ones I can't figure out how to remove. Also couldn't remove the vacuum slide cards. There's an oring underneath most of them in cv carbs and it's usually a few chips of dry rotted rubber left. Not crucial I just like to be thorough. Let us know if you know how to pop the bleed tube out. Otherwise a decent video.
@@LegitRaceCraft I see. This one usually needs to be softly tapped from the bowl side with a piece of wood over the main jet. Leave main jet in and tap with piece of wood. Remove main jet and push the bleed tube/emulsion tube/needle jet through the body of the carb. It has a notch so it only goes back in one way. Also the slide cards slide out after that and there's an oring on the bottom that needs replaced. Nobody shows how to do that with the old or newer style gs500 carbs. Usually what you detailed gets the bike to run good enough though. Also I noticed the floats were visibly at different heights when you put the bowl back on...I think it's because you didn't have them evenly pressed into their bore so the oring could pressure fit evenly. They were noticably uneven. You also balanced the throttle plates wrong. You just set the idle knob so it cuts the foremost idle hole in half with the right side plate. Then the balance screw adjusts the left plate to the right plate. Your guitar string method is okay but easily surpassed with a much easier and less fiddly method. Bisect foremost hole then balance other throttle plates to it and do final balance with manometer or vacuum gauges.
Hi, I was just wondering if you can be more specific (maybe with a picture or something) regarding puting the silicone gasket on the manifolds. I do not want to screw up something in that area :). BTW, this video is pure GOLD :)) Thanks
I don't think I can go in and edit the video since it has been uploaded. It's easy though, just get a tube of silicone gasket maker and put some around the inside where the carbs slip in and on the bottom where the manifolds sit against the engine. If your manifolds have a lot of cracks you can even coat them in the silicone gasket maker.
well after watching your video here I did a few things wrong with cleaning and if it is the thottle cable would you have a video on reassemble for carbs
Hello, I just cleaned my carbs for GS500F, 2009 MODEL. I had gas leaking into air box. Your procedure is very helpful! I need to readjust the clots to 13 mm from carb cup facing. After putting everything back, I noticed that my throttle became sticky. RPM takes few seconds to come back once I release throttle when it is not fully warm. When it is fully warm, RPM doesn't come back to zero at all. I know that I have everything back for sure as it was. Throttle cables are not swapped, vacuum hoses are as they were before. Carb has everything in place. Only thing I end up by changing is float height. It was surprisingly lower than 10 mm, which I adjusted to 13 mm. Can anyone suggest possible things to look? Thanks in advance.
Just bought a 92 gs500 that was torn apart. My question is where does the hose go from the top t-fitting inbetween the carbs? Bottom is fuel inlet correct?
It's been a loooooong time since I worked on that bike, but it should be a breather hose that vents out to the atmosphere so the fuel level can rise and fall without pressure. Sometimes they have a little hose that connects to a little box, and other times it's just a hose that connects to nothing. Double check when I said though, I haven't worked on this bike in a while
Thank you for your really quick response. I do not see any cracks at this point but I'm gonna take the carbs out again.... ;) However how about if I do not see anything that I should be worried about, how can I really check if it sucks hot air? Can I spray it with wd40 when is hot and wait for the rpm to go nuts? :))
warm air is thinner than cool air, so it makes it through cracks easier. If your idle is rising when it warms up then that is most likely what it is. I've seen it on a few gs500e's. Just seal up where the manifold mates to the engine and see what happens. If you don't see any small cracks in the manifold then I wouldn't worry about sealing the outside. Just inspect it well for little cracks on the inside or near the base
Jay Shipp Unbelievable, I took the bike out today for a ride (90k to be exact) with the intention to buy the silicone gasket maker and everything was perfect with the small issue that at 9000 rpm in neutral it spits black smokes......but Idle was ok EVERY TIME. Power delivery good as well.... I'm thinking carb sync? or float heights? What do you think? I was out for 2.5 h without any idle issue......wierd I would say
Did it all work fine after this? You didnt have any riding problems like stuttering on the highway before? You did not adjust or measure the floater heights?
Hi, Having problem starting my GS 500, after it had been sitting for a number of years. Will run for a few seconds if you spray fuel into the carb! When cleaning the Carbs both Idle jet screws are really tight and cant tighten or remove them. Got that bad feeling (something is going to snap!) when attempting to remove. Any suggestions? Cheers. Mac
I have a 92 suzuki gs500e and I cleaned up the carborators but when I put it back together and started the bike it rev 6 to 7 rpm and it stayed in that range did I miss something putting it back together
it could be that the throttle cables are too tight and stuck open, It is very easy to overtighten the throttle cables when putting them back in, so the throttle stays stuck open, or the carburetor butterfly valves are opened up too much. It's also likely that the carburetors aren't sitting in the black rubber boots tight enough, tighten the boots that they sit in, and then play with the main idle adjuster cable. Check the choke too, it could be stuck open.
99% sure it was because the throttle cable slack wasn't adjusted right. It needs to be down or low in it's perch not high. Then with any carb screw the idle knob in until it barely touches the throttle stop point and go a 1/4 turn more. That should be your starting point for warming up and final idle adjustment.
Hi, I was wondering if you would be able to help me. I've got one of these bikes but for some reason it will start up fine and it can rev fine in neutral but when it's put under load it cuts out almost right away.
Hmm, I can't tell which one that is that fell, these older videos of mine are grainy. The only place that it can go is around the float needle or in the edge of the diaphragm. There is another o-ring that size around the idle-air adjust screw usually. Check those places and compare against the complete carburetor. Chances are you have the other o-ring in its place.
I'm almost positive it goes on the diaphragm side. Just outside of the diaphragm where that hole is on the outer rim. That should be where your o-ring goes. If yours doesn't have an o-ring there then that is where it belongs. Both Carb A and Carb B should have o-rings there. If they both have o-rings then check your idle/air adjust screws for a missing o-ring. Most idle/air screws have an o-ring this size around the base (near the point)
not true. They can be cleaned with wire. Just don't ram the wire in and out multiple times otherwise you'll score the inside of the jets. Put the wire in once. Spin the jet, and remove the wire. It doesn't throw them out of calibration
I have gone through many of my videos and added the chapter feature that youtube added fairly recently. I must have missed this one. I'll check if it has chapters since it is one of the longer videos. if not I'll add them
See the description for chapters to jump throughout the video (or hover over the progress bar)

If you have a hanging idle check your air intake and filter

gret video, I actually have that idling issue you described. Would you know of any reason why rpm drop slowly? Thanks
