Question about 2000 Suzuki GSX 600 F (Katana)

GSX 600F idle and throttle probs

My bike has a mind of its own. Sometimes it runs ok, sometimes not. When the chokes on it actually runs its best, although it idles between 3k and 4k rpm's. With choke off it usually idles below 1k until it dies. Tonight when i came off the clutch it bogged the rpm's down real low and then all the sudden it just kicked in and took off. When I give it just a bit of throttle in like second it kind of sputters in and out like its getting spurts of gas. I tore it down to the carbs and cleaned them and then just put about a half a can of sea foam in the gas tank. Lemme know if you can help me out

    thanks man I'll try that this week. Do you mind helpin me out if I have any troubles? I'll post any problems I have on this same thread. I've worked on plenty of motors before but never a bike. I'm not very educated in carbs either but I enjoy tinkering and fixing things so I'll eventually make it happen, with a little help of course. Thanks for the advice I really appreciate it.

    Ok, I tore the carbs off again, pulled the needles and bottoms off, cleaned out the jets with a toothpick to where I could see all the way through them. I noticed on the bottom of the carbs there was an allen screw that could be turned, I didn't think I should mess with them so I didn't but is there a chance those need tuned? I'm not too familiar with carbs so I was just bein curious. I didn't understand what you were talking about with the spark plug caps too much. I pulled them off and examined them, made sure they were down tight, etc... Now I mentioned that my choke cable was sticking so i tore it off both the carbs and the handlebar so the next time I start the bike up it's probably going to run a little diff without the choke cable stuck and holding the slide halfway open. Pretty much what I'm asking is if the bike dies down with the choke slide closed like it's supposed to, what kind of air to gas ratio tuning do i have to do and how do i do it? Thanks again

    oh one more question. when your bike is warm, when the choke is turned off, is your choke slide supposed to close completely or is it supposed to stay like 1/2 or 1/4 closed? My bike still will not run with the choke slide completely closed but was running fine with the choke slide in like half open position after being on for about half an hour.

    I have exactly the same problem on my 1999 GSX600F. I took the carbs out last night for a really good (and I mean thorough) cleaning, put them back in and fired it up and I'm still getting the same problems with the rev range. Gonna try balancing carbs and cleaning air filter today, fingers crossed!

Hi m8,, just a couple things,, wen u stripped the carbs down and cleaned them,, did u take the main jets and cold start jets,ie the jet that the needle in the carb sits in,, and poke the dirt out with a pin,, so u can see threw all the holes wen held to the light, u have a blockage still in the carbs,, undo bottoms of carbs take the main jet and the needle jet out ,,and clean ,, make sure your airbox is sealed down on the carbs and jubilee clips are tight,,,1 at a time pull off the spark plug cap and pull off the cap from its ht wire and snip a little bit off the end so u can see copper or brass stranded wire then screw cap back on ,do that to all 4 caps, do these checks ,the bike will run good, ,, look more in2 the carbs tho ,, its almost certain u have a bloked jet still

Have a problem with a dr650 went to a full stainless exhaust open up the air box fitted 150 main jet .NOW bike runs rich on idle can turn airscrew home and bike will not stop .Could it be a choke prob

If it is running rich you have the wrong size jet fitted, tuning a DR650 uses jets sizes from about 130 to 180 depending what has been done to the engine & bike

Hi, Mike and the usual suspects are:
1. Throttle cables improperly adjusted or pinched.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

Will not stayed cranked. changed out old fuel, fuel filter, changed oil.

The Virago's have a tendency to clog up the carb. quickly due to sitting for a short amount of time, say a month or 2. Try and run some SEAFOAM in the carb. Remove the fuel line from the tank and force the seafoam into the carb with a turkey baster. Run the carb.s dry as best you can, force the seafoam into the carb. and let it sit for a day or so.Then try and start the bike off the seafoam, it will run and make a lot of smoke. Then hook the tank back up and see if that did the trick. Sometimes it will sometimes not, you may have to pull the carb.'s and clean them by removing the bowls and soaking them in a pan of the seafoam or something similar.

Stalls when I try to use throttle. Runs with choke. Sometimes rpms are up with choke. sometimes not. after warmed up i try to turn throttle and it stalls. I have cleaned the carbs/jets. The plugs are...

sounds like a vacum leak. get a can of wd-40 and spray all around the carbs when the motor revs up thats the source of the leak. fix or replace that part and ride into the sunset.

1988 Suzuki GSX-R750 Slingshot problems(fuel/air)

Sounds like ignition problems; I know you've had it serviced but check condition of spark plugs. Check all electrical contacts for corrosion, more specifically the timing pickup circuit, wires to coils, CDI connector. You're CDI may be the culprit, try swapping it out for a known good one. If it's back firing then enough fuel is getting through the carbs, so would indicate to me that the problem doesn't lie there. Hope you have some luck.

Afis problems

The injected SV will first of all check the temperature when first turned on . If it is cold enough then the bike will go to fast Idle which will be around the 2700 mark (not sure of this to be exact) and when reaching the next acceptable temperature it will drop down to 1800 and then finally down to its normal idle speed of around 1200 . I have found that the bike sometimes has a sticking link where the gold coloured bars that link the 2 throttle bodies get a bit sticky , spray some cleaner and a light lube on the pivot joints and free them up . When starting the bike in the cold , kneel down and peer into the triangular frame and see if the gold coloured plates move at all .

St1300 will not run below 2000 rpm

your bike has three different fuel delivery methods...choke , low speed or pilots in the old days, and main fuel rails or mains in the carb days. your choke or idle circuit is not working. on fuel injected bikes you have a relay which you need to get checked to see if it's a possible contributor. best to take to honda dealer and they can diagnose the problem. hope that helped a little sir.

05 katana 600f no spark!

sounds as if you have an issue with the charging system, try using a volt meter to determine if the bike is charging. To do so you will need to access the battery under the seat, with the bike running hook up the volt meter to the battery terminals, at idle you should have around 11volts when reving you should have around 13volts. If not you may have a bad stator or other electrical issues. good luck
