500mL very greasy on the starter bench with the wheels barely turning.

500mL with the 2nd gear passing (by relaxing the gearbox by 1/3 of a lap). The engine turns 70-80 degrees.
4th step :
500mL with the gearbox and clut
Operating Temperature :
110° engine at 15° outside.
120° engine at 25° outside.
Spark plug :
-Spark plug n°6 for temperatures from 0° to 15°.
-Spark plug n°7 for temperatures from 20° to 35°.
You can perfectly drive with a N°7 spark plug at temperatures of 0° but your engine will be less clean at low rpm.
You can also drive with a N°6 spark plug at 35° but your engine will be more unstable and more difficult to adjust. The risk of misadjustment is greater.
I hope my advice will help you!
