    Hallo Guys!
    I have completed 9000 km on my Apache RTR 180 but the top speed it could reach is only 107 km/hr. I have mentioned the problem twice to the service centre but they could not solve it. The engineer also said that the top speed of 125 km/hr, as described in specifications, is only reached under special conditions in factory. Since those special conditions are not mate on road, so the top speed of 107 km/hr is decent enough. Above all they are extremely afraid in opening the carburrator. This is a very unsatisfactory explaination. I have mention this problem to TVS company through their web portal also but did not got any reply or call.
    To me, it seems to me that the main jet is clogged and/or fuel level in float chamber too low and/or needle height is set too low inside the needle jet. I have watched various videos of CV carburrator disassembly and also have the required tool for cleaning carburrator, but I am not confident one thing. If I take the carburrator off, how to connect the throttle cable back a with proper tension.
    Please help!!
    Lean the AFR gradually and test the high speed. Till you reach a point where the top speeds satisfactory and at the same time the bike doesnt flutter at redline.

        I have completed 11,000 km on my Apache RTR 180 and have no major complaints so far but recently my bike stalls when zipping through heavy traffic...how ever the issue is there is a loud 'Thud' sound emitted when it happens as if something hammered the engine from the inside..never happened before...is it normal?
        Sorry didn't get the issue. Is it like you are in mid traffic and after 'thud' sound the bike stalls?

        It won't, you have to cut it near the exhaust pipe area. Not a big issue, can be done with jugaad

          Do, you think i should still check them? Or go ahead with AFR tuning?
          You can go ahead with checking the tappet clearance.Sometimes,a richer A/F mixture makes the idle rpm unstable so make the mixture a bit leaner and see if the rpm comes down gradually.

          Thanks for the elaborate description of steps and also the photo documents of the diassembled carburator. I have a few queries.

          1. Is it possible to adjust to adjust the float tang in order to increase the fuel height in float chamber?

          2. Is is possible to adjust the needle jet so as to make the AFR rich?

          3. Is it possible to adjust the needle of needle jet to make the AFr rich.

          Waiting for you response.
          AFAIK,you can only make the fuel rich/lean by changing the position of the jet needle.When you remove the jet needle from the piston valve,you can see there are 3 adjustment slots in the BS-29 carb jet needle.The clip if set at highest position will lean the mixture while if set at lowest position will make the mixture too rich.The factory set position is the middle slot.
          Adding a few pics of the jet needle..
          In this pic,the needle has 3 slots,the clip is set at the highest position which will make the mixture too lean.Hope you got it.

            Guy's I've been to the SVC today. Saw the new RTR's for real. IMO, they looked great People would go for the new RTR's for sure. The photos definitely not doing justice here.
            The Apache is ever willing to red line each cog, but the Rider ain't. Enjoy RTR, Safely. Period.

                Did you took any pics? Any idea about if we can have the headlights on our "classic" apaches?

                  +1 That is the only thing which in my bike looks incomplete or like missing something, If it is a direct fit and costs around 1k, I'll switch to it immediately.

                    Yes and no...the bike stalls with a loud thud...i've been using the bike for 2 years now and this thing recently started happening...i know the sound a bike makes when it stalls but in my case the sound is just too loud (as i said its like some one's hammering it from the inside)

                      Are you sure it isnt the Engine Kill Switch loose contact? Is the sound similar to when you kill the engine?

                        Same happened with me bro does it happen frequently or only the bike is cold started
                        Try warming up bike first then give it a try your problem will be solved .....i hope
                        Clutch is doing this due to cold start try this and telll.......

                          Kindly take your bike to SVC ASAP. The same is the issue due to failing one way clutch.

                            Thanks a lot for the detailed photograph of the needle as well as the schematic diagram. It it indeed helpful. I am interested to check any clogging of the main jet. If I find it clear, I shall change the needle height towards richer side.

                              Wow. Great post. Do all the things that you told apply to RTR160 as well? I'm looking to get a good carb tuning. So, approximately how many revolutions from the leanest side should the screw be turned to get half way(The 'stock' position as per your pic)?

                                +1.May be its the one way clutch issue.

                                The same thing applies to most of the bikes including the RTR160.If you are referring to the Air-Fuel mixture screw(shown in the below pic),then its around 3 and a half turns from the leanest position,that would be the optimum mixture.
                                If you are looking towards changing the needle jet clip position,then setting the clip at lowest position will make the mixture too rich.It has most of the effect between 1/4th and 3/4th throttle.The engine will sputter with fuel and you can experience lazy kinda feeling in the mid range rpms if you set the clip at that setting.Best,you can add thin washers to increase the height of the needle jet by a 'little' margin which will allow 'slightly' more fuel to pass through it.This will serve your purpose if you have a free flow air filter installed in your bike.
