Pass. I'm not THAT clever...
Do you realise how many holes there could be if people would just take the time to take the dirt out of them?
Sounds to me like there is a small bit of crap sitting under a neddle valve on a float bowl.
What usually clears this is turning off the petrol and running the bike right out of gas, then turn the gas on the the crap is pushed into the float chamber.
But then WTF would I know.

im not the op but i have a 20 year old bike..
Im gonna have a go at dismantlementing the crabs im sure their will be some blockage in there somewhere. im pretty nervous about the process though. cos if i brake it i can't get to work

Also drain the float bowls, some times it works wonders.

Well i have the CARBs of thank god ( Seriously ) . And well i may have already found the problem. One of the slide carb covers only had one of the 4 bolts holding the cover on !
Since i have them out i'll try and keep going to see if there are any blockages which is what i thought the issue. i'm gonna do a little blue printing too.
By the way i have a 1992 ZXR 250
right carbs out and back in again. There were no blockages at all, which i guess is a good thing.
Went for a ride and it seems the issue hasn't be resolved
i also made a mistake reasmbling the throttle so it looks like im gonna spend tomorrow taking it apart again. mybe i can just swap the cables around in the throttle instead.![]()
uhh if hes talking about the ninja chugging it could just be the lack of engine torque.
depends on the type of chugging.. is it full on shaking the bike (carb problem) or just the engine struggling with a 6th gear acceleration at 30-40k's?
I asked God for a bike, but I know God doesn't work that way. So I stole a bike and asked for forgiveness.
Well mine will chug in first great below 6,000 but not all the time . Also below 10,000 if i pull the throttle open it hesitates.
The problem is wores the hotter the bike gets. Im sure if i run the bike with the choke on the problems isn't as bad. But with the choke out the bike is much slow up high.
I've done a bit more resersh and im gonna loosen the pilot screw to let more fuel in. there was a post saying doing so made a massive difference to their bike ! So im gonna give that a shot . and to be honest a lean condition kinda makes sence so more fuel it is
Dose anyone know if i add more fuel via the pilot screw withh this alos add more full to the top end 12,000 plus ?
The pilot screw sets the mixture at low revs/idle. Once the throttle is twisted more, the needles clear more of the main jets to increase fueling. You do know that you have 4 carbs? The problem may be in any or all of them.
Sometimes the symptoms you describe can be caused by a coil breaking down under load, esp once warm.
Or even just worn plugs.

I am also fucking astounded as to how you do this to a new bike? It is beyond me.
As, has been said before the bike is 20 years old not new ?
oh and i was refering to your post here
from here

You will find the trouble is not getting hold of thevacuum gauge, but getting to the fucking adjusting screws!! You need a fucking expensive 90 degree bevel screwdriver for your ZXR250. I suggest you first find one of those!
Another suggestion whilst you are working on the carbs is to adjust the pilot jet screws, it really makes a difference. My bike had an unsteady idle and hanged after blipping throttle, slowly returning down. I suspect a lot of ZXR's are like this... running lean on the pilot circuits. I just used trial and error taking off the carbs, adjusting them, refitting and eventually went from to 2.5 turns out (factory setting) to 3.5 (richer) and its got a nice pulsing idle and the revs drop nicely now!
