    Switched to Motul Motocool, lets see if it works any better. At first glance, feels much more fluid than the castrol sludge which came factory fitted.
    So you finally got it done... The real test would be Bangalore Red Lights.

    Waiting for the review.

      Keep us updated about the difference/findings....

      Also total amount of ltrs to be filler in?
      Price of Motocool?
      From where?
      Do you have the DIY pics of the coolant change?
      and which will be better for Ninja Semi or Full Synthetic oil?
      Thanks in advance....

        I will keep you updated, don't worry!

        Motocool prices depends on where you buy it. Bangalore wheels in Rajaji Nagar was a COMPLETE FRAUD, selling 1 litre for 450 rupees or so. Orion motors in Koramangala sells it for Rs.330-350 and Motorcycle spares company in JC road it is Rs.300 for a litre.

        You require 1.5 litres for the Ninja. 1 litre goes into the radiator, and half litre goes into the white reservoir behind the fairing.

        Unfortunately, I was in a hurry so I did not document the process on DIY I had to also clean the air cleaner foam element so there was double work. But here is how you do it:

        1) Remove both fairings

        2) Open coolant drain bolt located below the gear lever near the left footrest. But a big drain bowl has to be placed beneath that.

        3) Open radiator cap on the right side and the coolant will gush out of the drain hole like a 10 year old badly wanting to pee!

        4) Unfasten bolts attached to the white reservoir on the right and drain coolant into the bowl after unfastening the lower hose.

        5) Get at least 5 litres of distilled water. First empty one bottle into the radiator, close the drain hole and let the engine run for a few minutes.

        6) Drain the distilled water solution which will still be lightly colored.

        7) Mix 40:60 solution of distilled vinegar and distilled water. Use ONLY distilled vinegar only, not regular vinegar which is sold locally. Put that solution in radiator. Run engine again and let the mixture flow through system.

        8) Drain solution. Then refill radiator, run engine and drain again, this time with distilled water only. Do this twice to get rid of the vinegar chowmein smell

        9) Now tightly plug the main plug and put left fairing back on.

        10) Clean the white coolant tank by putting distilled water and shaking it a bit to dislodge coolant crystal deposits at the bottom. Drain the water, and repeat the process again.

        11) Now the radiator is flushed and cleaned. Open Motul Motocool and pour it into the radiator. It will take around a litre. Make sure that you bleed the air in the system by switching the engine on. That will eliminate air bubbles. Once the radiator is filled up, close the cap.

        12) Replace bolts and hoses on the white reservoir and then fill it with half a litre of motocool.

        13) Put right fairing back on.

        14) Coolant change complete!


        I do not have experience with fully synthetic oil, so I cannot comment on that!

        • Ninja 250R Air filter element:

          There is one thing which every 250R owner in India must take regular care of - the Air filter element.

          It gets very dirty pretty quick due to the dusty Indian conditions so one should NOT wait till the normal service interval to get it cleaned. Just clean it yourself every 2000 km or so. A dirty air filter could affect engine performance.

          1) Open Ride side plastic cover. (not fairing).
          2) Open the three bolts housing the air filter element.
          3) Take out the air filter element and remove the plastic casings
          4) Clean the foam in a solvent like kerosene or spirit.
          5) Let it dry and return to its normal size. Note: After cleaning with solvent, I cleaned it again in detergent and plain water, and then let dry on its own.
          6) After drying, apply engine oil on the foam surface (both sides). I used 20W-40 oil, this is to trap dust more efficiently.
          7) Put back in plastic casing, re-insert into the bike and close all covers.

          I will post a pictorial DIY the next time I clean it again in a month or so.

          • Hey Guys,

            My first post here. And its in the Ninja ownership thread!

            Booked myself a green one on Friday. The long wait begins now..

            Comment


            • help!

              ^^^ congrats buddy.. The wait is worth. don't lose patience.

              I went for a small trip today. completed my breakin officially.
              i guess i would be the slowest in our group in term of break in.

              I noticed a "faint" sound coming from front side. its sounds like "cut", like a wire hitting a metal. it happens every few(4-5) seconds irrespective of the rpm or speed. Sometimes i forget about it, but then when i pay attention, it is there..
              Does anybody have any suggestions. Thanks

                  • Got delivery of my green Ninja today. At the time of delivery the PBK guy mentioned that normal unleaded petrol is enough. No need to go for XtraPremium or Speed. Said that got a circular recently which suggests the customer to use normal unleaded petrol. Guys, what do you think about this?

                    • I have been using normal fuel since the beginning without any kind of problem, However, you will find several advocating use of premium and super premium fuel.

                      Take your pick.

                      • Went for a 300 km dash this morning, first to Nandi hills and then across the Karnataka border on NH7.

                        The Motul motocool does not offer any additional benefit over the stock coolant in bumper to bumper traffic, though on the highway the engine seems a tad cooler than before.

                        And what a difference a clean air filter makes to the engine performance! More than 50% of the engine harshness I was experiencing was gone, and pick up has improved too!

                          Cool... Will clean the air filter as soon as I get time.

                          Is diesel good enough for air filter cleaning?? I am planning to keep some to clean the chain.

                            Diesel is cool. Manuals and the like recommend a low flash point solvent (like Kerosene), but that is only in the interest of safety. You can use 97 Octane fuel as well, as long as you don't burn your house down

                            Remember that the foam element will swell extra 30% after absorbing the solvent, so wring it properly and let it dry completely before snapping the plastic covers back on.

                            • Why not go for a K&N (or any other reputed after market filter) at least once the warranty is over? It breathes better than any stock filter and carries a warranty of 10 yrs or 1 million miles, whichever is earlier.

                              The cleaning kit from K&N is available at most outlets.

                              Does anyone know the part number for a K&N Replacement type air filter for the Ninja 250?
