    Would a ECU remap help? I'm curious and coming to your stalling issue, it happens to me like once in a few months and after I park and don't use my bike for a bit, its rectified, I honestly duno the issue, but it hasn't come to any point that I need to go to the SVC, and do please keep me updated on the earth mod. Honestly do enquire n see about piggyback ecu , you can even tune your bike to your stock exhaust

      Re: Honda CBR 250R

      I'm not going into tuning, and piggyback ECU atm. I just bought this bike to buy milk, veggies and chicken, and tour 500+ kms without a problem. 😛

      I confirmed its not a fuel issue, and add-on p makes no difference.

      If its a faulty spark plug, I would have problems when throttling; my bike shuts off when the clutch is pulled in, and the engine rpm drops below 1.5k. It happens once a week, where I use the bike daily.

        Just curious, there's tuning for commuting and touring too, just have to be specific about it, some maps offer better performance and fuel efficiency than the stock map, but not sure about the wear and tear of the bike, I guess it depends on how you ride and rev.

            Hi guys, today i noticed that the coolant level is too low.. I checked the level when engine was cold and the level was not even upto the lower mark. Now checked it after a 4km ride (because the manual states check when engine is at operating temp.) And the level is still the same! Am i checking it correctly? Odo stands at 1210 kms.

              After doing that, the bike felt smoother, with crisp acceleration.
              Can somebody confirm if its actually due to the ecu reset or a placebo effect?
              You've not reset the ECU by merely disconnecting the battery.
              Disconnecting the battery has no effect on anything except reset the clock. There is a proper procedure to be followed for doing an ECU reset (given in the service manual). You do not require diagnostic tools but the process isn't as easy as removing the battery.
              Please follow the service manual to see how the ECU should be reset. There are also results when you do a google/bing search for CBR250R ECU reset.

              it might require their diagnostic tool to be connected to do it. but first have them read out the dtc's (diagnostic trouble codes) and fix the issue and then clear the dtc's if any and then reset the ecu using their tool.
              You are absolutely right. The problem is that no one searches.

                No worries, fill the reservoir up to maximum mark. Your radiator was not filled up completely at the time when it was refilled and hence it sucked up some coolant from reservoir. If you can, just open radiator cap to check whether it is filled up to brim or not. If not, add some. Check for any leakage too.

                  Actually, I did the disconnect after reading it online! Not one site, but three confirmed that disconnecting the battery wipes the ECU memory. A BMW owners manual stated that disconnecting the battery resets the ECU. A couple other people reported positive effects after doing the battery disconnect on their cars.

                  I felt a difference. Throttle response changed. The benefit that I got from removing the air filter cover all but disappeared.

                  My exhaust started rusting, so I did this -

                      Where else you expect to purchase the OEM coolant Obviously it is available at HONDA svc cost rs 250.

                        Thanks mate! Sorry i didn't know if the bottle was available for us at svc.. Thought they would fill and charge us for the coolant and also labour.

                          In order to reset the ECU, one needs to disconnect the battery as well as ECM connectors for 5 to 10 min. On a ZMR that is.

                          CBR250R has a similar procedure, as explained in the URL below.

                            Thanks, for the confirmation. Thus what I did wasn't ecu reset. But it removed the 4k rpm intake drone. [emoji19]
