Question about 1985 Suzuki GS 700 ES

2 Answers

I have a 1985 Suzuki GS700E. the bike has 21,000 miles. The carbs recently cleaned and adjusted. The bike runs great, but wont idle. It slows down and eventually dies out at stops. How can I adjust the idle to a higher RPM so it wont die out at stop lights. Thanks Steve

    I adjusted the idle screw to get a pretty consistent idle when warmed up. So bike does not die out. I checked the exhaust temps with a temp gun. #s 1-3 are all above 325, but # 4 is running around 175. I know they all should be equal, but what could cause that cylender to run that cold?

If it will not idle, the pilot jet is your main problem - it's probably still a little dirty - clean it again. If necessary you can adjust the idle by turning the pilot screw at the bottom, connected to the shaft flange.

    It runs cold because the mixture is too rich - check the level in the bowl , the status of the pilot jet and the needle position.

Getting the pilot jets cleaned out is the big trick. If it will not idle, the pilot jet is problem. ------------ The carbs not adjusted properly Synchronizing and balancing the carbs will be a nightmare. I would make a diagram of what hoses attach where and mark each hose. If you remove any adjusting screws or jets, write down the number of turns it takes for removal and than put each one back the same number of turns. Before removing the carbs, drain them (assuming there is anything in them). Now get a spray can of Berrymans carbcleaner (or another brand), and fill the float bowls full of cleaner by disconnecting the fuel lines and spraying into each fuel line until the level in the line is reaching the top of the float bowl. Now wait for a couple of days while the cleaner softens the dried varnish residue in the carbs. Now remove the carbsas a set then dis-assemble and clean with a couple more cans of cleaner. check fig:-- I have a 1985 Suzuki - c4f1abd.gif

turning the idle screw won't get you to where you want to be. Those carbs are very touchy and need to be balanced but first the valve clearances need to be verified. For idle adjustment screw check fig:-- a4d978d.jpg

Adjust cylinder #3 to best idle. You may have to remove the covers over the idle screws. Drill each carefully with a small diameter bit, and extract by turning a screw a few turns into the hole you bored, and pop it out with a tug on the screw with a pair of pliers.
To ensure that the idle mixture was correct, you can use Colourtune, a sparkplug . You can see the colour of the combustion flame as the plug fires. When you see a bunsen blue flame, the idle is correctly adjusted. If you could not get a blue flame. Then the jets needs to be checked as well. The moral is that tuning by ear gets the best idle, but not necessarily the correct idle.
Once the idle mixture is correct, set the idle speed to high RPM using the adjustment knob located between the airbox and the carburetors. Cylinder #3 should draw about 10 in Hg (24.5 cm Hg). This is your baseline measure. If the motor is not drawing this vacuum, double check that the idle RPM and mixture are correct; a rich cylinder will not create the full vacuum.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

My motorcycle wont stay idle


What year, and was it first sold in CA? Many Asian bikes w/ carbs had restrictors on the fuel adjustments. Locks down so lean for emissions that they wouldn't even idle. Look for rejetting kits on the internet if so. Easy to tap out restrictor and rejet. Did that on a 2010 Suzuki and it ran great.

At idle left cyl misfires. Remove right plug wire at idle and bike dies. hold idle up and remove right plug wire and bike stays running. runs good on the road as long as you are in 2nd gear. Has good fire...


The two carbs are not balanced to each other. Balance as follows; Start the bike then increase the idle on the left carb to a high idle. Now unplug the right cylinder and the engine will slow down some. Now slowly turn the idle down on the left carb until the engine just dies. Hook up the right plug wire then do the same proceedure for the right carb. Now both carbs are balanced. Hook up the left wire and start the engine again. The bike will be running faster than you want so now adjust the idle screws on both carbs equally to get the desired idle speed. Please rate my answer. Thanks.

It sounds like its time to have the carbuerator cleaned more then likely you have some varnish build up in the idle circuit. I cant remember if that bike has a fuel filter in line from the tank but if it does I would recommend changing that first as it could simply be starving the motor of fuel at idle.

This sounds like an air leak ahead of the carbs. Air that hasn't gone through the carbs is leaning the fuel/air mixture. Cracked rubber fittings, "O" ring seals, gaskets, and clamps between the carbs and the cylinder may not be sealing well enough. Note that a bad head gasket, bad valves or loose spark plug can also let air enter. The problem will get worse as time goes by. Do a compression check to check the valves.. Burned valves and cracked rubber seals are normally the culprits. Usually, all the valves need is to be re-lapped to provide a fresh face on the valve and valve seat.

I have a 2003 suzuki marauder vz800. the bike will only crank and idle with the choke on fully. when i push the choke all the way in, the bike dies. what is the possible solution for this problem???


check your fuel strainers in your tank. you can also switch the fuel selector switch to reserve. if none of this works, then its probably your fuel pump

How do i adjust or tune up my carb on a 1985 suzuki gs 550 l runs but the has to be choked out


If it is running like that with new fuel the problem could be plugged idle jet circuits. The carburetors will have to be removed, opened and cleaned. You will need compressed air for this job. Good idea to replace all 'O'rings inside carb at this time.

Over idling


Hey bro, throttle cable stuck, see if the carb mechanism is closed. Sometimes when you gun it it'll stick open. Get access to the carb and see if it is open or closed. If open then it is stuck, figure out if it is the cable or the carb mechanism that is caught and lube it. If the carb is closed you might have an air leak causing it to run lean but if this were the case it's rev high, but not red-line high. Cheers bro.

Hope this helps!

05 suzuki katana 750 idle issues


Idle issues can be fuel/air (mixture ratio) or igition (spark strength). It sounds like an air restriction issue. If there is no blockage throught the air inake/filter, make sure you adjust the jets to specifications and make sure there are no float issues with the carbs.
