Look up 6 hats thinking Kev
this is a white not a black hat suggestion.....
Seemed a great way to stop over tuning then using other mechanical or electrical components to 'cheat' (term used loosely before anyone gets the arse!) the engine/rules etc
Re baseline, for B wouldn't that be a 583 of any age with stage 2 kit filter and dynotjet no air box lid and open can, with cam timing probably good for 51 ish so inside the rules but not on them
For A similar; PC turned so the AF is at a specified level (eg 13:1) with race can/s high flow filter with air box on
Again good for 62 ish I'd imagine so same within rules but far enough away a little more work can be done
Isn't this what the no tuning rule was kind of meant to do; stop hidden work affecting the performance without having to constantly protest bikes?
Only a thought
