    Finally, i figured out that the bigger screw above was the Idling Screw.
    Set out with my First ever Carb Tuning DIY.
    Raised the idling to 3000 rpm and then turned the Fuel Screw clockwise till Lock.
    Messed up the rotations count. So, not sure how much was it originally set to.
    Next, lowered the idling to around 1000 rpm.
    Now, turned the Fuel Screw Anti-clockwise.
    Turned it till 4 Rotations Anticlockwise but still the rpm was around 1100 only.
    Turned it 2 more times to around 6. By this time, the Screw was about to come out. Still, the rpms were only around 1100 - 1200.
    I thought i messed up some where and started the whole process again.
    Now, while turning the Fuel Screw Anticlockwise, turned it till ~ 3.6 Rotations.
    Still, rpms were hovering around 1200.
    Turned the Idling Screw and brought to exact 1500 rpms.
    Engine noise was sounding regular and stable.

    Now went through both the Tests.
    Raised the Throttle twice till 7 RPM and let it fall down. Both times, it stopped exactly at 1500 Rpm. First Test Successful.

    Started the 2nd Test. Tested till 5th Gear. Rear Wheel was rotating freely without any Jerks with uniform engine noise.

    Tuning seems OK to me but am not sure since after turning the Fuel Screw anticlockwise the RPM's did not rise to 1500 RPM, as per the Tuning Guide.

    So, now my Fuel Screw is set at ~3.6 Rotations Anticlockwise [2009 Model].
    Went for a small Ride of 2 Kms and after coming back, Idling was at exact 1500 RPM.

    Guys, please post your thoughts and suggestions.
    Guys, No Responses from anyone regarding my above Query that i posted some days ago.

    Anyways, have been doing some riding for the past few days since i tuned my Bike.
    The Cold Idle is at 1000 rpm.
    One thing i noticed is that when the engine is warm and if i stop and start the Bike, the Rpm initially goes to around 1200 rpm and then after some seconds it gradually moves to around 1400 - 1500 rpm and it keeps fluctuating between 1400 - 1500 rpm. i.e. the RPM Needle is not stable. What does this mean ? Something messed up with the tuning ? Should i turn the Fuel Screw more clockwise or anticlockwise to get a better setting ?
    I am not sure but i think when this RPM fluctuates, the exhaust noise also varies slightly.
    Please respond Guys...

I wanted to try this once too, but then since it might be harmful to the bike i didnt try out this idea.

      But 100ml wouldn't make that much difference, and you can add any oil to bring the level back to "F" if you like, the bike may run a few degrees cooler due to more oil in the bike though
      Was suspection on the oil because before oil change it was calm and smooth.
      Its the same rythem but bit increase in the volume .

      Any way ill have to go for service in at 7k will check.

      Sound was not that too much but felt deferent.

        Yes, that means that you have messed up your carburetor settings. Get it retuned by a good mechanic or by the SC itself.

          Till now New Pulsar 150 and Pulsar 180's Carb kits are not available,otherwise you can go for them,both new Pulsar 150 and 180 uses UCD29mm carbs,needle jets would be better with 117 mainjet,but brother RTR180 runs 120 mainjet,its bigger.

          Go to TVS buy RTR180 mainjet,or wait for its delivery on order,would cost around Rs.40
          Go to Bajaj buy Pulsar 180's needle unit.....be cool

          But if you have to buy kits for both motorcycles,it wont exceed 400 bucks to the best.Then find on the internet how Mainjet looks like and how needle jet looks like.
          Mainjet is the widest and the shortest jet.
          Needle jet is the longest jet,thinner than mainjet.
          Mainjet is screwed on top of Needle jet.

          Pilot jet is located separately,its is small.
          thank you mach bhai for your reply.. I will go for rtr main jet and p180 needle jet.. and for pilot jet i will go for which ever is available with first preference for rtr's..

            Same thing happened with me..
            (after i tried tuning the carb myself)

            But the SC couldn't fix it during the last service even though i complained, they just did some carb overhauling crap, charged me around 70 for it, and said everything should be fine, but the problem is still there.

            For now i just manage by accelerating a little after pressing the button start so the rpm goes to the 1400 mark.

            Is there any DIY solution for this ?? i dont think the SC people will be able to fix it.


            @Madhu: Do you get mak 4t oil in 100ml packets as well ? how were you planning to get 100ml of that oil ?

              it should be the same grade and almost the same way of synthetic or motul we follow

              for GS150R its 20W 40 we can use motul /gulf / shell 20w-40 mineral or semi with 15W-40 or synthetic ranging from 5w-40 to 15w-40
              -------------------------------------------------------------------------------------------------------------------------------


              Just follow the same method
              The Manual says Hero Honda 4T Plus SAE 10W 30 SJ

              • Hi Gspians I have few clarifications to make:

                To All

                Please respond whether you agree or not(Yes/No) and give reasons:


                1) Sound of GSR is like a Mixee and not pleasant.

                2) Heavy handling makes GSR most difficult to maneuver in traffic.

                3)The rear brake is totally disappointing

                My answer is Yes to all. Waiting for your reply and reason for your answer

                • @sameershiraj:[(1) Sound of GSR is like a Mixee and not pleasant.no its like rattling mixee

                  2) Heavy handling makes GSR most difficult to maneuver in traffic. my friend told me that changing stock handle bar to p200 one will make it easy

                  3)The rear brake is totally disappointing]add rubber to rear brake

                  @segagt_0:my friend is planing to give a p220 like seating position on his GS.is it possible?

                    [/B] Its not a mixxer, its a mini gixxer.

                    If your bike sounds like a mixxer then its not normal consult svc amd don't let them go off without fixxing.

                    There are several reasons causing the mixxer sound.

                    # 1 may be due to wrong carb settings or issues with carburator.

                    #2 engine oil or chain stiffnes due to lost of lubricant as a result of dust can also makes the
                    engine too rough.

                    #3 GS150R is also 2010 pollution complaint as per govt norms ( pollution means both noice and smoke) so its not the normal GS behaviour.

                    #4 owner handles the bike in a rude way so as
                    the bike also sounds rude

                    #5 when you test drive the GS you didn't feel mixxer, when you bought the GS you didn't feel the mixxer, but after several days now only it sounds mixxer so its a alarm for you to wake up and make up your avatar to keep in good form.

                    The above are few possible reasons,

                    Do take care of your bike properly in turn it illl take care of your journey smooother. [/B]

                    [/B] few call it as monster bike in 150 cc catagoryn and few call it as mini bullet.
                    Because of its bigger in size,
                    Even I had the same feel during my first three months later GS is easier than handling my splendor

                    This is not a light weight bike to manour and zip zap just like that on traffic jams, but its possible in GS where we need skills which will come automatically after getting experianced.

                    [/B] I won't relay much on back break alone I use the 60 40 method of applying both break, I feel it should be like that so as bike can be handdled better (front disc break is sharp so very quick sharp break + sick sucking back break = optimum safer breaking power for sudden stops

                    @ low speed traffic jams I use front break and keep[/B]

                    Those are my answers

                    @ sumitdey1

                    Try shell 10W 30 or try gulf or other reputed brands in the same range

                    I don't think you need to go for a synthetic oil in scooter as scooter is ment to be a smoother vehicle by default.

                        In short, GS is a bad bike. I agree with you. Not because what you said is true, but because you have already decided it is so, therefore no point in proving otherwise!

                        Please keep in mind that for every complaint, there are hundreds or more GS owners riding and touring happily

                          Answers to the following questions will fix your issue

                          1 when did you changed the engine oil last ?
                          1.1 if its SVC oil drain it and switch to shell, gulf or the best one called motul

                          2. Check the chain play (refer manual ) if its loose or too tight correct it with the help of svc or local mechanic.

                          3. Still if its there means just ask svc to lobricate the gear lever and oil gear box

                          While down shifting gear always use clutch fully

                          Svc change oil at first service that's somewhere around 800 kms after that the next oil change they will do it during 3rd service that's somewhere close to 3k on odo in between we need to change oil at 1500 to 2000 k on odo. Why because during the initial 2000 kms more scrapped metal dust will settel down in the oil.

                          Even I experinced similar thing during those kms and the above sollution works wonders for me.

                              The sporty look of this bike is nice, but i feel they wont launch it shortly here in india. Suzuki is very reserved when it comes to Indian market.

                              ...and friends i have completed 12 days ride in Gsr, the Odo reads 650 km now. here are my observations.
                              1. The Engine has been smooth, but in the morning kick starting is little difficult, but engine comes to life easily! Why this is so? any idea, i've seen viceversa situation in my neighbor's Pulsar 150. I initially do 4-5 kicks without ignition on, then i turn the key to on position and when i kick the engine starts, but with slow cluttering sound of piston it goes of if i dont rev the throttle.
                              2. Gear shifting is smooth in the begining, but lately from last 2-3 days shifting has gone a bit tight, i dont worry since the 1st service is due within 4-5 days.
                              3. Once i have crossed 85 KM in speed meter, just for few seconds. 3-4 times crossed 60 Km for overtaking, lest all within 40-50 km range. first i filled around 8 litres of petrol, but i dint calculate mileage. Later i got 58, 52, 49. hope from 2-3 services the mileage will average around 50.
                              4. I did adjust headlight, and result is just ok. I need to fix either silverstar or Halonix blue, which already Madhu has mentioned. And i am thinking to reconnect pilot lamps throgh DC, and replace them with LEDs, which a nearby autoelectrician has agreed to do.
                              5. Seating is alright, rear seat is really high, my wife struggled initially, but now she is adjusted to it.
                              SO ITS A NICE EXPERIENCE WITH GS150R. I THINK ILL GIVE HIM FOR SERVICE NEXT WEEK, AND WANT HIM TO BE A REAL PERFORMER

                                I think you are running in a rich mixture(as you are saying idle speed is fluctuating), try tuning again
