Q. I would like to know why Himalayan standard model mileage is 36 kmpl and ABS is 29 kmpl.

Hi Vishal. This difference might be between BS3 Carburetor & BS4 FI. I am not sure how ABS Affects Mileage. Mine is a BS4 Non ABS. I get mileage around 25(City, Traffic) to 35(Highway, Free road). From my experience these are the following parts which improves mileage 1) Regular Chain lubrication, correct chain tension. 2) Right tyre pressure 3) Keeping both clutch, throttle cable at correct tension( you will know when they are not working right by their response). Hope it helps.

@balaji Yes you are correct. The points you have mentioned really helps a lot in mileage of the bike. However, how does the vehicle with ABS or without ABS affects the mileage is still question to me.As per my perspective what I see BS4 means better mileage because it is standard set by the government of India so that vehicle will produce less pollution. Hence, Less pollution means less usage of fuel.
