Throttle cable maybe the culprit if carbies are 100% good. Check length of cable for kinks, squashing or undue wear on shroud. Does throttle grip snap back at all steering angles. Ball end of cable in twist grip maybe binding in the grip housing, cable often bunches at cable end from severe bending to get it in or out of slot.
Double-check the starting plunger is not loose, and throttle adjuster rotates freely for all carbs.
Check again (I know, it's a hassle) needle jets are all rising and dropping smoothly and in unison. A needle out of sync (on wrong notch) will effect idle speeds.
Tip: If engine revs high and you load engine (in first, slow clutch release, no throttle) and bike stalls, your problem is confined to one carby. If it's got some grunt (won't stall) you have issues with all of them...generally.
Cheers.

My 91 gsxr 750 will idle up and stay up. disconnected the throttle cable and manually revved it up an it still stays up. it will come down if it feels like it also when i apply a load or choke. the bike...


Sounds like carbs need a good clean out. The 1991 model GSXR was not Electronic Fuel Injected. A model this old may also be subject to the carbs being worn out and letting in unmetered air around the screws etc, which may be keeping the revs up at idle and causing a lean idle.
Applying load will source fuel from the next jet and hide the problem. Applying choke holds back some air which will help as it sounds like too much air at idle. This will not help as much when bike is warm.
Bottom line is your carbs need a good clean and service and maybe if they are leaking air they might need to be replaced.

Runs and starts fine but will not rev over 9,000 rpms, in neutrol or going down the road, runs great, starts great, revs good till 9,000. wont go over lke it cuts out. idles good. what is it, 98 gsxr 750...


First impression was why would anyone rev their motorcycle to 9 grand in neutral? I could see if you were in gear clutch pulled and ready for a "drag" or Race Start but in neutral?

Anyway I can't hear it so if the sound is like it hits 9k and starts popping then two things either an over rev limiter which I doubtr because the engine red lines at 13,500 OR you have a set of spark plugs breaking down under load

1991 GSXR 750 cutting on low revs


run a can of Seaforam in the tank..purchase from Autozone put in 1/3 to two gallons gas drive it around for at least 10 miles to insure it cleans out the whole carb system.if that doesnt work, check all carb hose fittings when bike is at idle spray some Chemtool B-12 ( also at Autozone) around the carb hoses and manifolds..if idle increses thats your problem. Caution: chemtool is very toxic wear gloves and a mask.

1994 GSXR 750 wont start


the carbs are proberbly blocked, you might have rust in your tank that will keep blocking, put an inline fuel filter in and get carbs cleaner, you also got a flat battery, give i little revs until it starts then adjust the idle

My Audi 97 A4 revs high when i start it and then .transmission pulls when changing


I have a 99 a4 and it revs to about 1200 at first start, after a minute or so it lowers to about 750 rpm which is the norm.It has done this since it was bought. Also when the air condenser/conditioner is on it idles high. The condenser is run off the engine so i also lose a few horsepower.

I'm not sure what "transmission pulls when changing" means though, needs clarification.
