Dear all,

I also face the problem. The exact answer is already given by srikantrl. But you should note that it is very difficult to adjust AFR manually. I have gone through almost 10 mechanics. No body has given solution. Most of the people told that it is becaz of valves.Finally in one HH authorized show room they have done AFR with tacho meter, That too when I approached second time . My problem got solved. Do remember ask them to set AFR ratio using tacho meter, making both screws initialize. My problem got solved now I am getting mileage more than 55. Previously it was 30kmpl only. For the oil leakage u need to change the packen seal. Dear all, I also face the problem. The exact answer is already given by srikantrl.
