    Abhijeet thanks. I already got one from Enfield dealer and it has the same part no. with Mikuni, so the possibility that it should work was high.

    However, things failed again. The bike is still chocking and running bad at slow speeds.

    I've called Bajaj's factory today and they said only Pilot Jet is not available. As you said they recommended the Jet Kit (Pilot Jet, Main Jet holder+jet) priced at Rs 126. He gave me the part no as 36DH1203.

    I would appreciate if some one can confirm the part no for Pulsar 150 Jet Kit.

    Till now money spend = Rs. 400/- with no help.
    Do one thing, go to the dealer and ask for the Pulsar 150 Parts Catalog. There you will find the part number mentioned. Atleast this is not P180 part as I have mentioned that number elsewhere in this thread. DH series part number is for Avenger I think. Just verify with them. Then again I think avenger uses the same pilot jet as P150.

    But I can safely say that P150/P180/Avy all these bikes' pilot jet can be used. Atmost maybe their will be slight performance/fuel efficiency losses. The idle adjustment screw can compensate for this. Definately wont cause knocking issues!!

    If the issues persists, open up the carb rubber diaphragm part and check for tears.

    And it would be helpful if you can describe the way your bike is behaving in details. (At what RPM knocking occurs, knocking on acceleration/on steady throttle etc etc)

      Today I received a call from Bajaj's employee located at the the state capital where I stay. He assured me that he will get the Jet Kit as the Pilot Jet individually is not available and will try getting it shipped soon. Hope he keeps up the words.

      I've set the idealing at 1000/1200 RPM and the bike makes sound as if its not breathing properly. The engine would roar then sound like about to stall but then will roar on and on. When I start riding, the bike feels normal and smooth while accelerating, I move over to 5th gear and keep accelerating, everthing is fine. But then when I cruise at 50kmph I feel fuel is not coming properly like the reserve is coming up, but if I accelerate at that speed everything is fine. I reduce the cruise speed from 50 to 40 to 30 to 20 and as I go down the knocking gets more and more, even with lower gears at lower speed knocking stays by.

      The difference was clearly visible. At idle RPM with light on, it can be seen that the headlight will glow dim and high, but with a little bit of acceleration it will glow high and not at all dim, but in my bike at 2000-3000RPM I see the headlight getting slightly dim when the engine stiffs, and then run fine for a few seconds and then again the same fraction of a second stiff.

      I'm really devastated with this stuff. At my place neither there is a good mechanic nor spares available. And now this problem is not going away. Wheneve I ride the bike I get dishurtened.

        Don't worry! Hope your problems gets solved soon. The symptoms given here points to a lean pilot circuit. Do one thing - open the screw to something like 4 turns and see. It should help.

          Abhijeet,
          What screw are you referring to? Pilot Jet or Volume Screw?

          I have tried opening Volume Screw aka Air Screw to a large extent, but no help.

          Thnx
          Ayush

              Problem finally solved.

              I got the pilot jet from Bajaj and got it replaced in the carburetor. However, the bike was still locking and chocking more often.

              One mechanic at Bajaj's outlet traced the problem to choke cable and fixed it.

              Now I'm back on road and the bike feels smooth as ever.
