Dear fellows,
My GTO 125 does missing when I stuck in traffic jams (frequent first and second gears) or when I reached 70-80 km/h mark and then press clutch till the speed lowers 50 or so and then try to accelerate again. Otherwise engine pick and its running is smooth overall. Currently, the silencer has a minimal smoke but there are oil sprinkles coming out from silencer upon engine revs up.
So what I should do, further decrease in 2 stroke oil mixing or there is something more ? My mechanic tells me to bear this if I want piston life.

Below is some extra information that might help you. Really sorry for taking your time.
Engine is recently overhauled. It has done 1400 kms so far.
During initial period, the 2 stroke oil mixing was very rich and the wasted oil (drops and sprinkles) was coming out of the silencer. After 500 kms my mechanic decrease the oil quantity which makes engine much smoother, got rid of missing by a margin (my mechanic called this missing as bharbhrahat or simply bhr bhr).
In the run so far, I never faced problems like:
A short plug, engine shutdown, engine overheat, bad fuel economy, issues in long run or climbing a bridge. Piston never seized.
Always uses oil pump (a brand new one) for oil+fuel mixing and uses Shell 2 stroke oil (the green bottle pack).
