2000 Suzuki GSX 600 F (Katana) - Answered Questions & Fixed issues

Question edited for a lot more clarity, full 'year make model'.. Question moved to model category. Of course if it is fuel injected, but you are near the crossover year. Do you see carbs? https://www.google.com/search?q=2000+Suzuki+Katana+600+does+it+have+a+fuel+pump https://www.motorcyclespecs.co.za/model/suzu/suzuki_gsx600f_katana%2000.htm ... ..

No you can't. You will burn out the switches. Just buy a used kickstand relay for $15 and a flasher relay for $8.71. There appears to be two relays, one for flasher and one for relay. When you write 'flasher/kickstand relay', you are indicating one relay does both because of the slash / https://www.google.com/search?q=2000+Suzuki+Katana+600.+flasher+kickstand+relay ..

Remove the carbs from the bike, then remove the bottom of the carbs to gain access to the floats. You want to flip the carbs upside down and set them level by bending the tabs.

Make sure the ECU is working properly. Check all fuses to make sure good. Check starter and battery wires for good connection and electrical current

Hey Joel, I am a little confused... is it an ignition fault ..or a transmission fault?? ... I think the different issues will show up as totally different symptoms.. First.. new spark plugs..(make SURE they are the EXACT FACTORY replacements).. and gapped correctly!! Is it a minor or intermittent miss... or is it a constant miss.... and it COULD still be in the carbs.. How did you sync the carbs? Did you remove the pilot jets and make sure ALL the air/gas passages were clean..(Brake cleaner sprayed thru ALL OF THEM!!)??.. Please tell me more --with details!!..Reply on here Thanks

countershaft seal leaking OR it may have a self oiler thats not adjusted right.

I had a similar with my Suzuki....turned out to be the coil, it would get hot and the spark would fade and eventually the engine would die and wouldnt restart till it cooled off...Good luck with it!!

change the fuel in tank,clean carbs ,change the spark plugs ,change the oil.check all brake lines ,calipers,and pads. check tires for weather crack in tread and side wall

faulty/sticking sidestand or clutch lever lockout switch

I have the same problem with my katana 750, I can't crack it and it tops out at 120.

Look at the back of the fuse block to make sure wires are in good shape and connected.

check clutch cable maybe loose enuf to work but not enuf to make good contact

The norm is about 1 1/2 to 2 turns out and to adjust it around that parameter to achieve perfect idling.

probably needs to be reset. try to disconnect the battery, let it sit a couple minutes the hook back up. If that doesnt help, sensor may be bad.

Your bike came in at 80 HP, the 99 year model had 86 HP you can check and see if that year had a larger pilot jet. you are running leaner because of increased air flow. Excellent in you can get more fuel with it. You should be able to go up to the next size and cure your problem. Your Pilot Jet is 75% cruise Mixture and 25% idle mixture. Rule of thumb....
If you go 1 size larger or smaller on the size of the pilot jet, you will change the fuel screw ~1.5x richer or leaner to retain the original idle mixture - Dennis Kirk 6am to Midnight Central: 1-800-969-7501 tell them what you want. You can go online and search also, many items are not listed though. You will find a bucket load of jets on their site. Happy Hunting.

Changing to a K&N air filter changes the air/fuel mixture for your bike, and you're probably hitting an overly lean spot before things start to even out. For bikes still running carburetors, which I think you have, you can compensate for this by changing to a slightly larger idle jet. Your main jet is probably fine (it's kicking in after the lag); it's the crossover from idle to main jet that's causing the flat spot.
Talk to your dealership parts counter to get recommendations about jet settings. They may suggest, for example, to keep your existing idle jet and go with a different main jet. Expect to try a couple different setups to find one that works best for your bike and your riding style. I would highly recommend keeping your original jets, though, in case you ever go back to the stock air box.

We don't know what you mean. Please expand.

If you are in a location with high humidity there is a chance water built up inside the tank. Best solution would be to completely drain the tank and refill with new gas. Run position on the fuel tap is 6 o'clock.

I would set the tickover screw on the carb up a bit to increase the tickover speed and set the mixture screw accordingly.

if it is air/oil cooled then the wind blowing on it wen your driving cools it. also the oil while circulating through the engine cools the engine.
