  • HOnda DIO BORe Problem

    hey guys
    ive recently got my honda dio bored
    and it was fine till 5000kms after bore and recently it started to give white smoke from silencer when it goes above 60 or when i raise suddenly.

    i went to mechanic n he said that the piston rings n the head guide and a valve is gone so i replaced them also
    but still the smoke from silencer comes and i am concerned about smoke as i have got it bored and not less than 5k kms were clicked

    so what could be the problem guys
    please help me out

      It's useless to rebore small bore cylinders like this .. mainly because they don't have accurate machines needed for this kind of work . What's happened to you is the usual course things take after this kind of job .. I see it happen all the time .
      You'd do best to buy a new cylinder-piston kit from Honda and have them fit it too ... will save you lots of trouble and money , even now .

          No not a new bore done ... buy the whole cylinder-piston-rings-gudgeon-pin set .. it comes as a kit .. not too expensive ( relative to my RX135 kit, for example ) . If you have Honda fit it at their service .. they'll guarantee the work for a period of time too .
          No , the silencer of a 4-stroke motor cannot belch smoke just like that .. remember that there is supposed to be no oil in the exhaust system .. unlike that was in a 2-stroke motor . Did you get water or oil into the silencer in any way ? White smoke from exhaust is not a big problem per se .. you can continue to run the bike like this . Unless it is accompanied by more serious problems .. like quickly depleting engine-oil level ... poor pickup and fuel mileage etc .

            Get the stock internals and revert back to stock setup.

                White smoke is due to burning of engine oil. The piston rings might be causing the smoke, get them inspected again.

                  New bore & the smoke still exists???

                  According to my knowledge goes, ur piston rings have not sealed due to an improper run-in & is drinking oil. In short, ur motor is burning oil! Sincere advice is to change the bore kit.

                    You've got me confused ... you did a rebore / resleeve of your original cylinder or purchased a new cylinder-piston kit altogether ?
                    A local rebore/resleeve job is always suspect ( I never seen them get it right even once ) . And it doesn't save you that much money too . In the long run it gets more expensive - as you may find out .
                    Anyways , if there is no other mentionable problems in the bike , you should know best as you've ridden it all along ... the smoke may well be from extraneous oil/water entered into the silencer pipe somehow . White smoke is not a reason to fret early on .. keep riding the bike .. it should go away with time then . No problem .

                      @hunkofgals,
                      Pinaki is right. Keep riding and checking the oil level everyday.
                      If the oil level is going down then only you need to worry.
                      There was a HH xtream guy with the same problem, (search in xbhp) and his bike quit smoking after a month or so.
                      Btw, wanna know what amount of smoke is there.. Is it like a very efficient 2 stroke or it makes you look like a rocket?

                          Didn't I tell you mate that due to an improper run-in your piston rings didn't seal-in & your engine is burning oil?? Now adding to that due to the (Crappy)free flow exhausts that u've used during your Run-in, your Exhaust valves have been fried! As told earlier, nothing can solve this except a change in the bore kit along with valves. Hope this is a lesson learnt in the hard way now...!

                            LOL , so you've been playing with exhaust pipes too !
                            Good idea to keep a sharp eye on the oil level - if the engine is leaking/burning oil , that oil has to come from somewhere .. no ? So there shall be a drop in the oil level in the sump if that is happening . Otherwise it's fine .
                            One more thing is your mechanic is good & trusty .. but rebore lathes available here are not . I always go for a new kit & parts fitted by the company service center when it is time to overhaul a old worn engine ... works out to be half the cost & trouble in the long run . Frequently even a new bore-kit has problems soon afterwards .. if fitted by the company service , they'll take care of it fully .
