      I did not exactly mean to say everything is common. A few things I knew about the engine oils. We will rest this issue for now.

      I would be helpful for other CBR owners if you could tell what kind of oils would be good for the CBR engine.

        @aargee - You just had an engine change on your bike and now you are using Motul 3000 10W-30 oil which will void your warranty again as the manual clearly mentions to use Honda recommended oil. Again 15W-50 is not the grade of oil which is supposed to be used on the CBR. We can either use 10w-30 or 20w-40 mineral or synthetic. I don't want to get into the technical details of the oil but why use some other oil when you just had an engine change on your bike and not use Honda recommended.

        • A Honda recommended engine oil is a safe bet than other oils. Once again I reiterate, the oils provided by Honda are very good.

          • @Nils - I have NOT used it so far. I only bought it & its perfectly possible to use it on my 6+ yrs of Activa or return back. I'm more than aware of warranty.

            And Ravi, talking about Honda Engine oil, JSP only stocks 20W-40 & in my strongest suspicion is the culprit for my earlier engine failure.

            • All other things remaining normal,,,,,A thicker oil by virtue of density has better heat carrying capacity than a thinner oil.
              Synth or mineral, it is better to change oil within or earlier than stipulated time in our own interest.

                  No.. That compulsory flushing was practised by Bajaj SVC.. two years ago on P180.. And i also had my uncle saying the same for his Unicorn the same time at Honda SVC.. Now, they dint tell a word of flushing for CBR.

                    RG, I highly (very highly) doubt that. Engine seizure due to engine oil is very very unlikely, and that too by engine oil recommended by the manufacturer is impossible. If you see Honda's manual, it clearly says you can use different grades depending on climate conditions. There is some defect in your engine internals build that caused the seizure. Its clearly evident as it propped up in just 1000 kms of riding. It will take many thousands of kilometers with spurious engine oil for an engine to seize.

                      Ji & Ravi - That's what I'd assumed too; but think of this, more the viscosity also means that time taken for circulation & that affects the flow through the thin oil lines; especially with C250R's engine where things are highly engineered to precision for its light weight (34.7 Kg) construction. So probably the denser oil couldn't be circulated well at higher RPM's.

                      Not underestimating, but, that might not be the issues with other high end vehicles such as ZMA, RTR or P220 (where the case is completely different due to oil cooler).

                      I'm not saying this is true, but, that was one thought.

                        Talk to them and see if you are allowed to pay after seeing the bike....tell them you will pay the remaining amount on the spot after checking the bike....
                        Else atleast check it before RTO registration...that is a MUST.....

                        Once its registered there's nothing you can do about it.....
                        do tell us about your conversation with the showroom ppl..

                        cheers.....
                        yeah that would do...ill be going to the showroom today...ill let u know...
                        cheers man!!

                        Please suggest
                        same here...sterling honda chinchwad asked me to do the same..they want me to pay the full amount and ill get my bike in 10 days...

                          If the engine oil does not circulate properly, the temperatures would rose to high first. I remember you saying the engine temperature before seizure is just normal and not abnormal. If its abnormal, the sensor would have indicated the same before the seizure.

                          • ^^^ Good point; Like I said before, its just in my thoughts. The damn HMSI is totally not responsive to what has happened. They're just doing their job in this country. If it were some other customer, they would've probably been happy saying the engine block is replaced.

                            But for people like us who run the extra mile out of passion, these are mere excuses.

                            C'mon, come to think of it...
                            - They've an engine tested at free of cost; they can do a R&D & fix the issue to make better products
                            - They could've expedited the letter to RTO along with the new engine
                            - Worst thing is, they say they cannot reset my ODO. I don't feel like its a new bike. If I need to calculate the ODO clock with the new engine block, I've to subtract current reading - 1205 every time

                            • @aargee - As everyone suggested, I too would suggest you to stick with the oil what Honda recommends in the Manual.
                              I don't know much about the technical aspects, but its better to follow what is mentioned in that. And also, engine oil cannot be blamed for the seizure as majority of the CBRs are filled with the same oil and there haven't been any similar issues encountered.
                              Just my thoughts.

                                oil is circulated under pressure through the engine by the oil pump, and with heat the oil thins out more than when cold..if in doubt ,take a drop of oil when the engine is cold and see ..and take a drop when it is hot..oil will be thinner when hot . so no chance of reduced velocity of oil flow when hot..we are using quality multi grade oil and not single grade here.
                                My suspicion is on the coolant , and it's quantity...when the seizure happened you had noted no increase in temperature...how can it be ? there is a metal to metal rubbing at high velocity which would definitely increase engine temperature beyond normal....It had happened progressively with bike refusing to go above 115 kmph..a clear result of piston skirt coming closer to bore and making contact and creating friction ..the moly coat had prevented immediate seizure and when the coating was rubbed off, bingo your engine seized..
                                then why the temperature gauge didn't show increased temp ?
                                The sensor depends for it's output on the circulating coolant to convey the temperature through the gauge..if the coolant level was low,then the density of coolant in contact with the sensor will be low..and hence lower reading...and effective cooling cannot take place with lesser coolant...just a theory..could be wrong.
