    • No idle adjustment screw?
      It may not be near the throttle body, but it has to be there somewhere!
      For example, R15 has it on RHS side cover. Can be adjusted by poking a screwdriver through.

        No owner's manual esp., Fi one will ever give you these details.It will be on the throttle body and will adjust the bypass air volume for idling.

            I'll take a through look into it again when am home. Will ensure I take care that the screw is not broken.

              Neither do I have much knowledge.....merely trying to help,based on past experience..As the actual owner you are at a better advantage to explore the bike and find it out..

              • On a hunch, I spoke to the C250R technician seconds ago & he confirmed...

                CBR250R does not have idling screw; its quite unlike R15 & the throttle body is electronically controlled.

                This is for Metal_Maniac too from one of his previous post - http://www.xbhp.com/talkies/627469-post.html

                  Kindly post a pic of the said screw,for us to determine if it is the Idle adjust screw,since the SVC Mech themselves have clarified it's absence.
                  My worry is you should not end up turning any other adjustment and end up with broken or wrong setting which will ruin your otherwise good CBR

                  Kindly read Mr.Aargee's clarification above on this

                    Ji...no need to Thank me, I did nothing compared to what you've been teaching me & all others here

                    I remember saying this long time back somewhere in the post, may be else where. Reason being that, I'm under the impression that closed loops DO NOT have idle screw adjustments.

                    If I'm not wrong, R15, P220 Fi, ZMA, RTR 160 Fi should all be open loop systems.

                      Yes, you are right about R15 being open loop. It is actually a cheaper version compared to closed loop. R15 lacks an exhaust sensor, however it makes up for that by having a map sensor.

                        You were Good enough to share an important info and so thanks for it..
                        The R15, Pulsar 220i,and RTR are all without the Oxygen sensor in Exhaust,and so open loop ECU which works by reading the resident ROM data. The ZMR,CBR and Ninja 250 all have Oxygen sensor and are closed loop,ECU which learn and adjust required parameters as they work.

                          • Ji few more important updates...
                            - Went in for second 1st service today ; once again 10W-30 wasn't in stock & they changed 20W-40 Honda Genuine engine oil; I asked them to change the engine oil filter despite they showed me that the filter is good. I noticed some paint marks though!!!
                            - Outside the workshop there're posters indicating fully synthetic oil to be used with C250R; obviously these people didn't carry them; blamed HMSI
                            - Coolant level checked & it was fine
                            - No additional noise from engine

                            Here's the interesting part - I was told that my head cover was slightly damaged during the transit of the new engine & HMSI has sent for a replacement for the head cover. They said it takes a day to get it fixed & asked to bring it on Tuesday. I'm paranoid to touch something that is working fine. But its quite surprising how HMSI found that the head cover is damaged. Had the ASC not told me, I would've not known it either. What's your take?

                            Guys - How're you gear shifts? Mine is smooth & easy, but, I hear a loud Khad sound when I shift, not with 1st gear, but mostly with shifting down. Anyone???

                              Good you checked and changed to 20w40 WITH OIL FILTER...and also the coolant level.Synthetic oil cannot be used on NEW engines which are not used and set in.
                              How bad is the head cover damage, have you seen it ? In any case it is the cover on top of head,and comes right under the Petrol tank. If the damage is not bad,and not likely to leak oil in future, you can ignore it.
                              If you have to change it then , the fairing, petrol tank etc., have to be removed and refitted, ,and the New one put back WITH NEW GASKET...One full day must be sacrificed...
                              If the damage is a Dent of 2mm or so, then best to ignore...if more better to get it changed.
                              Just my thought.

                                Oh!!! right; but it still serves the purpose to idle the engine RPM right?

                                I don't know what to say!!! I was having the same thoughts in mind & was confused; now you just said exactly what was on my mind. Now I'm in double dilemma, should I or shouldn't I? May be remove the fairing & check? And what could be the impact? Till date I haven't experienced anything & its like more than month since the new engine is in place & 1050+ Kms covered.

                                And yes, the new head cover comes with the rubber gasket.

                                Ji, so when would it be ideal to use fully synthetic? I thought we could switch to fully synthetic ASAP after 1st service isn't it so?
