  • If smoke is coming means then the bore might have been ceased some time before and it can happen bcos of incorrect oil level or shortage of oil level in engine.
    Second reason incorrect tap valve adjustment also leads to smoke in engine.
    Third thing, the in correct adjustment of clutch or wornout clutch plates will make gears tight.

  • Expert Hi,
    After reboring there are chances of getting dark smoke due to oil particles left out in cumbustion chamber.Mileage will improve after usage for a while.

  • See there is no relation between hard gear shifting and black smoke comming out at the tail pipe (exhaust)
    1. hard gear shifting due to improper clutch adjustment, or worn out of clutch.
    2.for black smoke i do agree with the Prashanth's secoend reason or the piston ring gap is incorrect.
