Xian, suggested wording?
The snorkel is the inlet into the airbox for a 2nd gen SV removing it makes a bigger inlet.
The R6 air filter most certainly is the inlet into the airbox from the ram air tubes. Take the air I'd off bike and look at the opening with and without airfilter installed.
For the R6 I know the BMC street airfilter is same inlet opening as stock. The restricttionon this model airfilter is removable, the top hat must be installed.
"Air filter must be use, aftermarket filters are allow" (same as AMA SS)
"Aftermarket filters are NOT allow"
The conditions are what cause the grey areas.
"The R6 air filter most certainly is the inlet into the airbox from the ram air tubes"
The "Inlet" is the opening for which the air enters the "Air box". That would be the inlet opening through the frame.
The air filter is completely enclose by the air box and the "Snorkel" of the air filter is still larger then the inlet of the air box.
Stating the filter is the inlet, could be said about any air box, as the air must pass through it... giving it the properties of a filter.
The "Snorkel' on an R6 is part of the filter. It attaches to the filter and not the air box.
Claiming the "snorkel" opening as larger then stock would also leave the door open for every dimension of an aftermarket filter to comply.
If that is the intent of the rule, no filter could match stock...
Hence, why even say aftermarket filters are allowed, if they can't pass the rules?
And if CCS clearly has a rule against one brand of bike, why do the rules not say this?
