  • Scratching sound from engine

    Hi all,

    I ride a p200 and all my services where done @ PBK with 20w40 veedol (PBK used that oil when i knew bajaj recommends 20w50 which was okay for me since i liked to change oil @ intervals of 2500kms)

    Last time when i serviced @ 30k they told me that veedol has been stopped and from now onward will be using bajaj oil 20w50.I said okay!!

    From that point afterwards i get a scratching sound the engine something like piston is being brushed by cylinder somewhat.I contacted PBK and they said the plug something [i don't remember where] had water content and beacuse of this it's the sound.Phew!!What a lie?But still the sound is there.So i knew they can't sort out the issue..

    Guys..so please help me..what could be orignal issue.Is it beacuse of the bajaj oil.The sound is not there all the times.Sometimes i can hear it on idle speed or at times in 2nd or 3rd gear at slow speeds.

    help...
    Regards,
    GinsB.

      does the sound also come while starting --sometimes like metal scratching to metal, during kick start or self start ??

          Kind of hard to understand these things by words; is it tappet noise?

            Since it started with the change of oil grade/type simplest would be to reverse that first and see if the problem goes away , without delving deep into the engine trying to locate the cause . Try a bottle of motul 3000 4T plus 15w50 .

                I second Pinaki.. try reversing back to old grade and see if that solves. Are you witnessing any abnormal vibration along with the sound ? Any white smoke out of tail pipe ?

                  Hi,

                  Thank you guys for the reply...


                  @Pinaki -- very true...i was thinking of doing that this weekend..Lets c if that helps!

                  To that i have one query the recommended one is 20w50 right!I was planing to buy ACTIV XTRA - 20W-50.Which one should i go for?

                  So would using 15w50 be a cause?

                  @Aneesh - Yes.....somewhat similar to that.

                  @Prith - No and no smokes from silencer.

                    No...I hope not...


                    Also earlier the oil used was 20w40.Should i revert to that itself or use 20w50.

                      Pulsar 200's recommended grade is 20w50 . So you can use that grade itself if you get , or 15w50 is good too . Motul 3000 4T plus 15w50 is having great feedback from pulsarians , so you can try that ... ensure you get genuine motul from authorised dealer . The Bajaj oil being correct grade should have been great ... were you present in person when they did the oil change ? Do that this time .. and drain the old oil when the engine is hot . Clean & lube your drive chain .. it can be a source of funny noises .

                        Ha ha..very true...


                        Also lately i have noticed that it has got a starting trouble too...It would fire,but the engine won't start ( not a cold start n battery levels are fine )

                        Is this related to the engine sound... Bike needs a thorough check up and m not goin to PBK.

                          Sound from engine

                          Hi all,

                          I reverted the oil and it seems the problem exists.The local service where i showed told me that it could be related to the clutch bush.

                          Also the bike sometimes starts in gear.....He told me that it is time to change the clutch plate.Is that so?
                          Regards,
                          GinsB.
