My GS 150's fuel average is very bad since this week.
I put 1l of fuel in tank when there was no fuel in on position and reserve was full.
Got 19 kmpl.
Again checked this by filling 1l and got 22kmpl with very gentle hand on throttle.
I drove at speeds varying from 40 to 60 but sometimes till 80 also but no sudden acceleration.
Also i cleaned and oiled air filter and changed the pump on the second time.
So i took my bike to suzuki mechanic and explained him.
He checked spark plug which was just fine. I asked him to check air filter so that maybe it has been oiled too much but that was also fine.
He advised me to drive it on long roads and keep speed high like 80 then you will get good average.
I said in my heart it's obvious that on long roads fuel average increases as there is no stop and go motion and fuel consumed Is less.
What might be the issue? I got it tuned at 1975(don't remember exactly)
And now it has 2477 on odo. Next tuning Is due on 3500km as i am using Liquimoly.
Kindly share as to what I should do.
