After tunning the carb several times nothing changed so I got the following things done:- Carb cleaning and tuning, tappet setting and and changed the air filter too from SVC. But still the problem persists. Any solution?[emoji20]
    According to ASS, carb cleaning is to loosen the screw under the carb and drain it. They never open the carb. Even if they do, they don't touch the top part. And that is exactly where the possible problem is: a small hole (tear) in the diaphragm. This can also cause the symptoms you mentioned, in addition to the probable causes rightly pointed out in the above posts.

    But, first check the main spark plug. This can also cause a similar trouble.

      Thanks bro, so can it be a problem with the diaphragm?

        Hey guys... over the weekend I installed a voltmeter to my bike and I was wondering if someone has kept track of the voltage supplied by the battery under the following conditions for reference -

        1. Engine off / key on
        2. Engine on / lights off
        3. Engine on / lights on low beam
        4. Engine on / lights on high beam

        Would really help me keep track of what to expect in terms of voltage.
        1. 13.2-13.4 if you use the bike everyday. Else, lower voltage may be seen.
        2. 13.6-14.6 (up to 15.0 max), depending on engine rpm. Constant above 3K rpm.
        3. Voltage keeps going down if the engine is idling. Starts charging around 2K rpm. Maxes out to 14.6-15.0 at around 3K. Then constant.
        4. Same as above. 5W doesn't make a difference.

        Note: don't worry for 0.3 to 0.4V differences from the above. But 15.0 is maximum, or battery life will be affected.

          Torn diaphragm syndrome occurs more frequently in NS than any other bike, I heard :banghead:

            So can I check it myself or is it necessary to open the tank cover?

                Yep, you need to open tank cover, tank & air-box too. It will be a considerable effort.

                  Hey guys ... have read a lot about NS suffering from a torn carb diaphragm ...

                  What are the symptoms of a torn diaphragm which are pretty evident ?

                  Issues which I am facing - (Tyre pressure at 25/32)
                  1. A lag in pickup at lower revs. Once I cross 3.5 - 4K rpm there is no issue accelerating and the punch goes pretty close till the redline. Earlier even with a light hand I could easily accelerate however, now is a different story at lower revs
                  2. No matter what rpm I blip the throttle, there seems to be a nano second cut and then a slight but noticeable jerk when it comes back to life. I know this can't be related to AFR since I got my bike CO tuned to 1.5 by the svc centre guys

                  Any suggestions ?

                  On-bike Voltmeter readings -
                  1. Engine off / Key on - 12.9 - 13.0
                  2. Engine on / light off - 14.2 - 14.4
                  3. Engine on / light on - 13.7 - 13.9

                  Are these readings normal? [MENTION=74543]krixna[/MENTION] - this second half was directed to you bro ..

                    A small leak in vacuum will create trouble when the throttle is open very little. This is because the butterfly is almost closed and very little vacuum reaches the diaphragm. You can't afford a leak in that small vacuum you get! Get the diaphragm checked. Improperly seated diaphragms can also cause small leaks.

                    Point 3. It should reach your previous 14.2-14.4 reading, above 3K. Your readings look quite normal. We have to take into account the accuracy of my voltmeter and yours too . As far as the battery is getting properly charged, and you are not blowing any bulbs, we can assume the voltage is in the correct range.

                      Hey krixna,
                      How are you.you back after a long gap.
                      Good to see u here.

                      Krixna don't you think this issue seems identical to what I used to have.?

                      A black pipe near the rear shocker not being setup correctly had resulted in loss of Vaccum and non of the svc were able to fix it. Until I spoke with krixna.

                      Get that pipe checked.

                        Hey, Hi !!
                        Hmm yeah. Seems funny, but that pipe under the air-filter box acts in a strange way. Sucking air through there has been known to create problems

                          The pipe near airbox is crankcase breather...
                          This on right side of airbox attached below it...
                          On the left near rr unit there's a pipe going to carb for some air intake.. This is a guess i am making coz when you cover or block the pipe the engine dies...

                            There is one under the air filter. You'll find it in front of the rear shock absorber. Sounds funny that a drain pipe in the air filter can create trouble, but sometimes it does! [MENTION=70781]nikzcool[/MENTION] knows that.

                              Thats the crankcase breather.. If the engine oil is filled above the specified quantity some the oil comes out through that pipe.. Until then it is responsible for taking out the blowback gases from crankcase and reuse in combustion process....

                                I am not sure of which pipe you are speaking.
                                But the pipe I am speaking of is having a white part connected at one end (a blocker possibly) and other to a chamber.
                                As per what I have read and understood from other people this pipe is used to create Vaccum in the chamber and at low revs the maintaining of pressure gets affected and at higher rpm the loss is somewhat compensated .
                                I could be totally wrong with what I just said.
                                But one thing is sure. Getting this rectified solved all my cold start problems. Varying rpms . Sudden death when applying break .
                                It's been 6-7 months I got this fixed and my hate I had developed for my ride has all vanished.

                                Other experienced members would be able to clarify what that pipe is for.
