    proper gear ratios for my p180

    guys ..plz tell me the correct gear ratios ...i mean which gear to shift at which rpm...and a gears peak torque..

    i don't follow these gear ratios as iam not ripper..in future i may want to coz now my bike is in run in period

      during run-in .. change gears below 5000 rpms .. and keep the engine rpm where it feels stress-free .. where you feel it is revving freely

        Shifing up & down depends on your bike's kms done, riding purpose, situation, etc. Here are some of such conditions:-->

        For first 0-1000 kms, Company recommends staying below 5000 rpm (65 kmph in 5th)

        For 1000-2000 kms, it is 6000 rpm, which should take you to 75 kmph, as per meter.

        For mileage riding, shift up at 4500 rpm, down at 2500 rpm. Try keeping higher gears.

        For "enjoyable" city riding, shifting up @ 5-6 krpm might just do it! Down shift @ 3 krpm.

        After that for drags, you can shift gear up at 8500-9000 rpm. Preferably, 9000 for 1st gear, and 8.5k for the rest.

        --
        Also remember, The 2 Spark Plugs generate a lot of heat due to which the company made sure that, one spark plug switches off beyond 6000 rpm. So, beyond that engine might not be so fuel efficient. I still remember that hard riding brought my mileage down to 35 something ... Good Luck!

          4k rpm is more optimum than 4.5k for upshifts, for downshifts 2.5k is fine

          For "enjoyable" city riding, shifting up @ 5-6 krpm might just do it! Down shift @ 3 krpm.

          After that for drags, you can shift gear up at 8500-9000 rpm. Preferably, 9000 for 1st gear, and 8.5k for the rest.
          its 9500 rpm for all the gears shifting there will take u to 8000 rpm in the next gear which is the rpm where peak bhp of 180 lies.. shifting up at 8500 rpm is not at all suggested, revvs wud drop to 7000 rpm which is very very less while dragging..

          Man this is news to me.. where do u get such news from?? one extra spark plug generates more heat???
          First u tell me what the spark plugs are used for??

          after 6k one spark plug switches off???
          man, its at these high rpm both the spark plugs are made best use of..

          You tell me any other bike's name whose efficiency doesnt drop at high speeds..

            thx guys u helped me a lot.....and yes i usually do a city riding so..shifting technique is also the SAME as u said...

            @ road ripper...two spark plugs was too a n ew news to me..never heard..

                i know dude....dts-i stands for digital twin spark ignition tech......i was talkin about the instance where...one spark plug get switched on higher rpm to reduce heat in the engine as described above...

                not that much noob!!

                  At high speeds the valves of the engine open and close at very high speed giving very little time for the combustion stage to occur so as a result some of the induced air-fuel mixture go unburned and find their way out through exhaust. This happens in a conventional single spark plug engine as the spark plug is located in the center of the chamber, The DTS-I engines have one spark plug placed at the either sides of the chamber which helps in an even flame propagation thereby igniting the entire mixture better way at high speeds. The DTSI engines burn fuel in a very clean way and leaves very minimal residues at the exhaust. Back then when the DTSI was released all the Then bikes were stuggling to meet the Stage II pollution norms of the Indian government but the DTSI engines not only surpassed the norms but were ready for the future Stage III norms even!!!!! and all these without even using a catalytic converter...

                    + 1 to that. Even i havent heard anything like that. And am sure that the "one spark plug switching off" theory is BS.

                    No offense.
                    When everything comes ur way, u r in the wrong way ;)

                      No offence taken. But Dude, I'm absolutely sure of this statement. Sources of info:-->

                      1. Earlier, before Xbhp Crash, there was information about this... It was by a good & trusted member, name I forgot.

                      2. Moreover, when I complained to Bajaj mechanic about overheating, he was too SURE when he said that above 6 krpm, one plug switches off. He mentioned the rpm himself!

                      3. It's logical in a way. When 4 krpm driving can "cook" its engine literally, due to lean mixture, what will happen at 8+ krpm?

                      --
                      See, 2 sparks burn more fuel at once. This results in fuel being burnt off completely. Hence, the fuel mixture becomes lean, as air flow is more, and fuel proves to be lesser than machine's capacity to burn.

                      So, All the new Pulsars run a bit lean, increasing the heat.

                        you still dont agree with me do u?? Do one thing just visit the Bajaj website and enter the pulsar link, once u are in click on P200 after that click on Technology and then select Twin spark, Doodh ka doodh aur paani ka paani ho jayega.. No way one plug switches off at higher rpm, you still believe that just a spark will overheat the entire engine???
                        You can still experiment one more thing, if u still think the sparks will overheat then take an empty Cigarette lighter (with no LPG inside) and just keep it sparking for sometime, let me know if the surrounding metal where the sparks come from overheats or melts or whatever...
                        Just a spark makes no difference in contribution to heating of an engine

                        Duh!!!! Burning more fuel will lead to lean state??? nope, its the other way dude..

                        ya, thats true the pulsar's engine run on a leaner mixture contributing to engine overheating, in fact almost all the engine's run leaner in india to comply to emission standards and also to extract better efficiency from the engine.

                          Another set of reasons why Pulsars heat up more than the competition.

                          1) Short stroke (OverSquare) Engine and hence free revving
                          2) Engine is casted with Aluminium as the prime component
