How do we increase bike average?

I have two bike Bajaj Pulsar 135CC and Bajaj Avenger 220

Pulsar 135 = 65KM/L

Avenger 220 = 49KM/L

Advice:

1.Bike start after 5-6 hour's put your chock.

2.self start your bike relax for 10 seconds don't give accelerator

3.Run your bike less than 55 KMPH or less than 4000 RPM
