Heres the way I do it and how I was taught by a pro racer.
Start up the motor and let it idle on the box (yes the old school method)
and tune it so that it spits out fuel while idling. about 100 - 120 degrees (i know, i know my rod is gonna break and some B.S.) Let it idle for 3 thanks none stop making sure it never runs dry.
Then clear it out (get all the oil out of the pipe and run it on the street
start slow 1/4-1/2 throttle input for 2 tanks leaning each tank
the 1/2 to full throttle leaning till you get it at 200*
set you low speed and idle and run it a little rich for a few more tanks
To determine when it is time to race tune the motor will get fatter and fatter on its own on track then haul butt.
I'm on my 8 gallon on the original rod.
