Question about 2002 Yamaha TT-R 250
I rebuilt by carburator now it idles wrong. When idling it revs up and down spuraticly, tried adjusting all cables and throttle/pilot screws. Don't know w.t.f.
You might have an air leak somewhere. chack to make sure you did not loose any o-rings from the diaphragm cap or the pilot screw. also check that there are no cracks on the intake boot. VERY LIGHT sprays of the either or carb cleaner can lead you to the source.

Check the inlet manifold rubber has not seperated from the aluminium part of the manifold ,this is very common on the ttr 250 and will cause the exact problem you have,if it is seperated either replace it or repair it with some good quality rtv sealant avoid sillicone sealant as it is not petrol resistant and will turn to jelly.adam
