well ..... from what i have done ...break in procedures just to idle the engine for a few tanks then gradually on the track start to tune to racing pace...
Idle the engine on the starter box for a few tanks? Ummm...

real hard for me to swallow...the motor would over rev...anyway just my thought...
I guess you should read the article properly... Although you open the throttle fully, that does not mean the engine will rev 30,000 rpm or more. That is why Josh mentioned that the main needle (HSN) needs to fully open 1 more round than the stock needle settings until the engine flames out at full throttle ! This is to ensure that the engine will not rev high and will sound blubbery with fuel even when full throttle. The RPM will not be high during this kind of break in at full throttle.
Doing this makes sure that you break the engine in at rich settings and with a lot of lubricants flowing in the engine. Idling the engine on the starter box will cause more damage than breaking in the engine rich at WOT. You actually cannot determine if breaking in the engine by idling ont he starter box the engine is broken in at rich settings. During idling, not much fuel and lubricants go in the engine internals.
