My recently overhauled splendor - My uncle using it. He clocked 1000+ KMs within 2 weeks (full highway ride). Speed under 50KMPH. He said he used approximately 12 liters of petrol and the mileage is 83KMPL. That is a 2000 Model. He is happy with the bike now.
In your splendor I am not sure, If everything is correct at least we can expect 70+KMPL. Changing tubeless wider tyres may not reduce the mileage by 10KMs. It will reduce but around 3-4 KMs.
I am getting the thoughts like: some one is stealing your petrol or Petrol is not accurately filling in Petrol bunk. Please change Petrol bunk and check.
I always get cheated in petrol bunks. Now a days I switched to Shell - No Cheating, they fill proper amount of petrol and correct bill will be provided.
