    It appears that most of the premium fuels are just normal fuel with additives; use only Speed97 or Shell Vpower from a popular bunk if you wish.
    I started using higher octane mostly speed or Xtra premium like 8 months or soo ago, bikes alright, no issues, I only go for these fuels for the preservation of the fuel pump more than anything, I been using 300v for the past 5000kms almost I think it's life is coming to an end compared to throttle oil which by 2000kms engine feels a bit rough or, 10w40 lasted a bit longer.

      Using premium fuels gives better fuel pump life? Haven't heard of this one so far. What's the secret?

        Not life, more like preservation. Because I've seen like rusted up fuel pumps because of bad quality fuel, then again the owner of the r15 never took care of his bike that well, it had water mixed with the fuel.

            I am not able to shift down gears after a 700+ kms trip. It has started from last 120kms.

            I pull the clutch and only able to shift down one gear and rest all gears are not getting engaged as it should be. I have to push the gear lever from my toe towards the engine by-fro so that it gets its stiffness. It becomes totally loose or else.

            What can be the issue? Loose clutch play or anything else


            It was a terrible experience in b2b traffic, at a time I was stuck with 3rd gear as it was not going down easily due to loose play of gear lever

              Checked the gear box? What about your chain sprocket? Did you tighten and lube before going on your trip?

                Chain sprocket were recently changed 6K kms before. Bike was fully serviced before going on trip. And I was continuously riding at 110-120 for entire route.

                Checking gear box in what sense, can you explain. That will help me

                  I was of the opinion that the ECU, which can make calculations in a millisecond, would never allow the bike to idle below 1500 rpm, but it's not the case. The bike sometimes idles poorly, causing stalling in traffic. This stalling happens only when the engine is hot, clutch is pulled in, like bumper to bumper traffic.
                  ECU still controls the fueling, and it also does all the millisecond corrections that you've mentioned. You've got to notice here, all idling in a throttle body is either taken care of by a stepper motor or the throttle plate with a separate motor controlled by the ECU or plain screw types, it depends on the manufacturer. The ECU controls the fuel spray with readings taken from the TPS which determines the amount of air sucked in by the engine. This is still cable operated, remember, not RBW.

                  Start off with the shift lever first. Inspect if there is any unduly play or slack or loosened tire rod. The CBR's linkages are made of very good quality steel, and are extremely robust. Secondly, if the linkages are fine, you should probably check your gear shift rod and spring that goes inside the engine, if we have a faulty shift rod spring, the gears won't slot be it upshift or downshift as they are supposed to.

                  Cheers!

                    Sounds to me like your clutch wire needs to be checked! Might be because of too muuch play like you have mentioned

                      Guys small update on my oil, changed to 300v 4500kms back, oil level is at 1.5ltr still and oil is good for 1500-2000 kms more, may opt for the same or shell advance, depends on my preference.

                        I think you should push this oil to at least 6K.

                        Please post this to Lighting thread under Universal section. Also you could try some LED lights as these days HID light craze has come down to a certain level after introducing LED lights.

                        When did you changed chain and sprocket? Wanted to know the ODO reading.

                                Happened to me once. Turned out that the bolt which attaches the gear lever was loose. Well, I reached home and the whole lever was hanging.
