5 tanks is cutting it a bit fine
Maybe they just want to sell lots of engines
12 to 15 tanks if you want the motor nicely bedded in and to last a long time.
Might seem a little long winded, but a bit of effort at the start with a new motor goes a long way. Heat cycle it for the first 10 tanks, then slowly lean it out until you hit 12 or 15 tanks depending on how it feels and sounds, then lean her up and go race hard. You have PM.

If the motor is bedded in, remove the .2mm break in shim. This will make a big difference.
It should be running .5mm - .4mm of shims. With the ultra hot OS P3 plug .5mm would be preferable.
