Hello all. Just picked up my 1st bike and it is a 98 katana 600F with about 15k miles. Didnt start when I got it but wanted it. Got it to start by replacing choke cable and it wasnt running steady. Idle would fluctuate and get below 1k and cut off. Adjusted knob and would idle at about 15 fine. Took off the air vent and found that 3 of the 4 carbs had the (forgive me if I am calling the piece wrong) choke blade/shaft moving up/down. This is on the air intake side of carbs. If I could get some help I would like to see if I can do the job myself. I can work my way around an engine just need direction. Also asked someone I know regarding the top half of engine sounding as if it was ran with no oil and maybe the lifters need adjustments and he stated since it is oil cooled it was normal for it to sound rough. Dont believe it but maybe I'm wrong. I did do oil/filter change. Valvoline 10 40w. Thanks again.

I can tell ya right now that your carbs are gunna need a real good cleaning and you will probably have to replace some of the internal rubber pieces. When the bike is running those blades should rise with more throttle. If the fourth one isn't, you probably aren't getting ignition in that cylinder.
A good way to test is to fire the bike up and let it run a minute, then spray the headers with water. The header pipe on the cylinder with the fucked up carb will be cold while the water will boil off the other ones. If that's the case,pull that spark plug and make sure getting spark. If so, time to clean the carbs.

hi mate ,try lifting the slide up with your finger or a screwdriver if you can't get to it , if it doesn't move freely ,you could undo the screws on the top of the carb and pull the slide out but personally I would just remove the carbs and give them a damn good clean . Fuel goes like varnish if the bike has been sitting for a while and the orings go hard . you will never get your bike running well if you don't pull them out and clean them .
Thanks for info back... I did run it and all 4 pipes are hot and I see the gas going in on all 4. What would be the next step. Again thanks for help.
maniac if it's not an srad or a gsxr what would the bike be classified as. It's a 98 suzuki gsx 600F. Just so that I know.

It's a Katana. The gsxr is a sport bike. The katana is classified as a sport touring bike. Less power. More upright sitting position, shitty suspension, thinner wheels. The carbs on those bikes get real gummed up, real easy. Pm me, I got real nice pictorial walkthrough for disassembling those carbs, and probably a manual stashed away on the internet.
