Honda 125 sometimes white smoke

[waqasahil]

Hi everyone i am new here I recently bought cg 125 2009. Also its my first bike ever. I need your kind suggestion and help in this way. So come to the point is that The bike has no extra noise from engine. Its ride is smooth and also has good speed. But the problem arises when i drove it about 50 km or more or when it get heated, It emits white smoke when i give it some accelrator after drive. In the morning and few minutes drives dsnt give any smoke. One machenic told me that after changing two or three time engine oil will resolve this issue. Keep in mind this is second oil changed by myself first one (hevoline 20/50) i changed after 400 km and now new oil is 100km old (AHL) but still it smokes. Please let me know and share your experience.

I think it's piston is changed but that person doesn't clean or change the silencer
When silence gets hot the oil gathered inside the silencer because of compression leakage start burning and smoke came out.
This only the case when silencer was not changed

^ adding another point.
Change your engine oil with something better use valvoline or liquimoly. Try to stay away from havoline.

simple or quick solution bataon ?

sniff that smoke while reving it hard.. if it smells like oil smoke (usually which comes from 2stroke rickshaw) then I have a bad news for you.

If it smells like a rich feul burnt improperly then you only need to get you carburator tuned properly.....

Have the cylinder bored and replace ring piston and valves along with stem seals, head gasket and cylinder jain and u r good to go... Being a 09 model i am pretty sure it would be requiring headwork right about now...

However before doing this i would advise check oil level which comes out at the next change interval....and see if its decreasing or not if its less than what is supposed to be the than headwork is the only solution..

Silencer doesnt need to be changed after headwork.......if the bike is burning oil the burnt up oil exists in the form of powdered carbon inside the silencer, and can be see by placing finger inside the whole of the silencer.

That carbon/powder clears up within one or two weeks after getting the head work done...however during that duration when u rev it u may see a bit of a black smoke and may confuse it with bike running rich....but that is the silencer clearing up..

Agreed but you can't say it's in powder form it's like thick paste which burning emits smoke
Engine gives black smoke when mixture is rich not silver like but it's another problem if you been confused between silver and black.

It's the sign that head work is needed means leakage in valves or piston.

[waqasahil]
