idle for 2 or 3 tanks at the richest setting possible. this loosens up the piston sleeve etc. i always use a fan set at high as close as possible when doing this.
i also have the wheels of the ground.
start driving it 4th tank slowly. with blips at closer intervals each time.
5th tank same as fith tank but slightly quicker and i make sure it doesn't go over 100 degrees celcius. i use a temp gun for this.
start leaning 6th tank and i do this at my favourite track i race the most at.
alway use the fuel you race with.
and i always treat my motors with microlon before a drop of fuel hits any metal parts, and i also mix microlon into the tank when i start driving it for the 4th and 5th tanks only
