I have pulsar 150cc dtsi since 11/11/15.
It gives more milage than my previous bike.
It gives 54 kilometre/litre average.
I have not spend even 1rs for engine work or any automobile work.

So I never fear to go far.

1) start daily morning by giving chock and start by kick.
2) check tyre pressure after every 15 days.
3) speed shpuld be maintained as per given in manual.
4) run engine ideal after start engine and before stop engine for 1 minute.
