    even i had read somewhere that..it had 1.9lts in reserve..!
    but i went through the manual...and i couldnt find it anywhere in there..!

      well..my bike is hardly 1 week old..so i sure as well wont be ripping it..!

        and according to me your absolutely right about how the electronics behave when fuel comes on reserve.
        again...is it 1.9 lts or 1.2 lts..??

          Also..when it goes into reserve...the fuel meter starts flashing..right...?
          and once it starts to flash..the km reading on the display changes..i guess it shows how many kms we've done on reserve...!
          Am i correct..?

          Total tank capacity 12 litres.
          Reserve capacity 2 litres
          Usable reserve: 1.9 litres
          Shivi is right, the F comes on when reserve comes&goes away about 5 kms.after refilling. Its written in the manual too.

          My two cents: Don't rely entirely on the F tripmeter-it may come on accurately in running, but later when you park your bike on the sidestand&start it, you'll find it showing 2 bars in the fuel gauge&F meter would have gone. This is due to the fuel flowing onto one side, which results in erroneous readings. Later when the vehicle is straight, the F meter will come up with 0 again, but in the process you might have lost atleast 5-10kms.
          So what I do is, when the F meter comes on in running, I reset tripmeter 2&rely on that.
          One recommendation is not to use the entire reserve fuel. Since this bike is fuel injected, the fuel pump needs a minimum amount of fuel in it to operate correctly, else the pressure is too low to suck fuel. Keep atleast a litre to be on the safe side-the fuel pump costs about Rs.7K FYI.

          But on the overall handling department NINJA beats R15 anyday.
          Of course Sir the R15 is no match for the Ninja on the track or even on a highway, but in our Indian bumper to bumper traffic the R15 will be easier to flick around due to the weight difference of around 30-40kgs.
          Maybe jd666 can comment on this, as he owns both.

            thanks bro, and thats a very useful and valuable info. Even I was advised by my mechanic from where I took the bike. He said not to ride long when the bike comes up in reserve.

            Okie I remember one more thing, i hope you can shed some light on this bro - my mechanic also advised - not to let the pump guys insert the fuel tap nozzle too much into the tank while refueling. Can you shed some light on this...if it is valid

              I never heard of this, but guess its for the same reason-fuel pump exerts pressure to suck fuel, so maybe he thinks pushing the fuel nozzle too deep might create some back pressure&interfere with the normal functioning of the pump!

                yeah I think so as I remember him saying the sudden pressure of the nozzle on the pump can create problems, well I always tell to the pump guys to keep it in there hand only... or else I have seen them thy just leave it and then i hold it

                • I remember getting the same advice. the reason given was the fuel sensor placed in the tank. if they insert the nozzle too deep inside the tank, the tap nozzle might hit the sensor/ fuel pressure might also damage the sensor, causing the fuel indicator problems. not sure how much of it is true, though.

                  Comment


                  • i think the sensor is too deep inside to be damaged, though it always pays to be on the safe side and i too shall follow this

                    Karizma's fuel meter is damn accurate i tell you and FZ's one of the most funny and whenever the level drops below3(i.e.2) i fill her up

                    Comment


                    • dint hear about the fuel filler, though yeah, running on too low fuel will cause the pump to suck in all the dirt/muck at the bottom of the tank, and will get clogged.

                      I have seen a number of bikes, in fbd ( atleast 3 what i can remember ).

                      Owners generally have a habit of running on empty. or reserve. The issue is that the fuel pump keep sucking in the dirt at the bottom of the tank, and gets clogged. they were lucky they got it replaced under warranty, but i suggest do not ride on an empty tank. Keep atleast 3-4 litres of fuel always.

                      With regards to handling, the ninja is leagues ahead in terms of in gear acceleration, so cutting ahead of traffic is easy.

                      Flicking the bike is a different scenario because of the difference in weight. The R15 is more flickable in that regard.

                      Both bikes are very closely matched if you are riding in heavy traffic. Also the price tag of 3 lakhs vs 1, and cost of spares, etc plays a heavy role in your riding. I will take chances more readily on the R15, than on the ninja. But on the highway or a 2 way road, where i would leave my lane to the opposite lane to overtake, i would overtake 2-3 cars on the ninja, rather than maybe 1-2 cars on the R15.

                        • * How exactly u all check the milage??
                          this is how i do-i refuel when odometer starts showing 'F' note the amount
                          reset tripmeter,run the bike till it shows 'F' and calculate..is this accurate??
                          are there any other effective way to check milage??
                          * my bike makes some funny sound(phoooooo..)from its tank as if its talking
                          to me..Is it a problem of some sort??
                          * Regarding looks,i dint like the rear part of r15,i am ok with the tires but not
                          with the seat..Did any 1 alter it??or is it possible to alter it??like the r125

                            The tankful-to-tankful method is much more accurate.
                            Next time, fill it till it's full, and reset the trip-meter to zero.
                            And the next time you got to fill it up again, note down how much fuel goes into the tank to make it full again, as well as the distance covered.
                            The mileage will be the distance covered to when you fill it again divided by the amount of fuel that goes in. It's a pretty reliable method, but as always subject to human error. But it's much more accurate than on a reserve-to-reserve method.

                            • Has anyone done the tappet adjustment... my bike has not been has smooth as it was before... i'm thinkin i need a tappet adjustment.. there isn't any tappet noise which can be heard as such...its jus tat the engine is not feelin smooth enough and mileage has droped as well... any inputs

                              • ^^ tappets should be set between the first 2.5-3.5 k kms of the bike. and then on every 3000-5000 kms, or maybe every alternate service for optimum running.

                                remember the clearance values - 0.10-0.14 for intake and 0.2-0.24 for exhaust.
