  • White smoke out of p 150 exhaust

    Hello Bikers


    I need to clear a few doubts regarding the white smoke comming out of my bike's exhaust.


    Bike History : Its a P150 2003 model classic without self start. Done 37k Kms successfully . I recently got its clutch plates changed and properly serviced one and a half months ago. No change in the bike's heart whatsoever. No boring done till date nothing.

    Problem :Recently I had to visit my mechanic for issues with front disc brake. During that time I discussed with him regarding possibility of overheating of my bike. I am not sure it overheats because there is no accurate way available to me to find out.

    Still I did the spit test[ spitting on the bike engine and observing how fast does the spit evaporates,I must say it was a few seconds.

    My mechanic's suggestion : After discussing the problem he pointed out to me the emission of White Smoke when the bike is given race in neutral condition. His point was that my bike is eating the oil and hence the oil is getting burned up and thrown out of exhaust.


    Thus I should go for a change in :
    • Piston
      Crank Repair
      Half Pack nut
      Suzuki bond
      Block Boring
      Valve


    The tentative cost for the above mentioned job is expected to be Rs. 2000


    My Dilemma : I am confused because I cant know for sure weather all this stuff is needed to be changed or not?

    Is there any other way that I can know it myself weather I need to go for a bore job or not?

    Is it necessary to get this job done? If yes is it to be done urgently?



    Thanks in advance , Your support is anticipated.

      Yes it is required. White smoke indicates worn out rings & needs replacement. Though this thread is for P180, the symptoms are the same - http://www.xbhp.com/talkies/help-me/...sar-180-a.html

        Dear MOD and aargee thanks for the prompt approval and reply. Having agreed with your point that it is inevitable,I want to ask one more thing.

        Is it advisable to get this job done by mechanics? Or should I go for a Bajaj service center ?

          Bajaj A.S.S any day. You can hold them accountable for the work they do & they're bound to fix with genuine BAL spares.

            is this the estimate given by your service center? because it is too low.
            i think that you don't put your bike to extreme conditions like repeated full throttle riding, long tours etc, in that case you can still ride your bike for daily commute within city for some more kilometers.

            is your oil level going down too much too soon, if yes then you need this rectification.

              This estimate was given to me by a local mechanic. I am living in bhopal right now so will have to search for a Bajaj Service Centre.

              i think that you don't put your bike to extreme conditions like repeated full throttle riding, long tours etc.
              Yes I dont rush the ride. I enjoy it.

              is your oil level going down too much too soon
              I got the oil checked yesterday and the mechanic told me that right now the oil consumption cant be said as HIGH. It is there but not in a substantial quantity.


              DOUBTS:
              • What would be the cost at the ASS ?
              • Is it for sure that this treatment would be the end of problems?






              Hey Prince , you are always ready to help man! I really appreciate that. You are a High Quality Member.

                i will suggest you go for new block piston set instead of reboring. at ASS it will cost you around 4000-5000, depending on what other things they replace, like valves, stem seals, etc.

                thanks for appreciating..........

                  Hey bro, went to a bajaj dealer and service center . He said that estimate is around 5k. But there is no guarantee or warranty against the item parts. Now this is of some concern.

                  One more thing I wanted to ask, is it for sure that this job is gonna solve the problem?

                  I have another option of selling this one and going for a new bike as this one is already 7- 8 years old. If I get the block piston changed by how much years would it run with no error whatsoever , also given that I take care of this babe as per the rules?

                  The mechanic also said something about crank play. Any idea about this? What if their is something wrong with the crank? Would the expenditure increase or would it be steady under or equal to 5 k?

                        white smoke and probably the first thing thats probably wrong with your bikes is the piton ring.

                        Since the you have not rebored it even once . Go for that with a change in the piston head and basically new rings.

                        Crack play is well not a major issue and pretty much a part and parcel of the older generation pulsars.

                        But honestly no amount of speculation we do can come close to what your mech has seen in your engine. So if you are certain he is not taking you for a trip go ahead and and get it done

                          You should immediately get a new piston and do the boring of the block.

                          The boring job should be done only once on a block and if after some time the same problem reoccur change the block too.


                          PS: Boring the block will only save few rupees, so I feel it is better to change the block itself along with piston.

                          The local mechanic quoted you a good amount which might increase a bit, but make sure that he knows the job that he is doing.
                          It's not the hours you put in, it's what you put in the hours!

                            If the Piston and the bore themselves are in good shape, then I doubt if they need replacement.

                            The smoke 99% is due to worn out rings and I believe just replacing the rings with good ones should make the piston last for quiet some more time cause it has only done 37-38K. Unless the oil changes weren't done periodically(on-time), the piston/bore should still last.

                            If you ask me, I would go shopping for the original parts myself, not go to the ASS but rather go to a known good mechanic and get it fixed under my own supervision. I have heard a lot of stories about ASS billing you for the new parts while reusing the old parts and sure they won't allow you to be there while it is being worked on. The known mechanic can also play with the parts, hence I would want to be there while each part is replaced and the engine completely fixed.

                            Regarding selling it off - hmmmmm its just 7-8yrs old. I would recommend you take the problems as a part of biking itself as such things help us get to know more about the bike and the relationship grows stronger. If you have the means, you might as well want to get another new ride while keeping this one. You have used it for a while and believe me it sure will be tough to part with it and you definetly will miss her

                            Whatever you choose - wish you all the best.

                              hmmnnn............

                              hey bro, i was out repairing my own bike...................

                              go for block piston change............since your bike is around 40,000 kms old...........chances are that your crank also needs work...........now there are two ways of it, either replace or get it repaired..........even a repaired crank will easily last 10,000 kms atleast. .............u can choose........

                              however, since your bike is already 7-8 years old.........if you can afford one...............purchase a new bike and sell this one by just replacing piston rings.
