what do people think?

why is it you can buy an "aftermarket" air filter for a supersport bike, but not a "racing" aftermarket filter? no one is refused availability. and it is not more expensive. i watched a guy at vir today ride his ass off in lighweight supersport. rack up a 25 second lead. and D Q'd because of a "race" filter. ummmmmm aren't they "racing" bikes in those events? did the filter cause his huge lead? NO!! itr was the guy's first ever SV race. they could have told him to sort it out, but no. they were'nt   very nice either. the rider is a nice guy and would never do that intentionally. even the guy in second place backed him up. ::)

Yeah, that air filter thing has been a sticky issue.

Seems as though SV650's are the big problem.  The filter's inlet cannot be bigger than the stocker in Supersport.  K&N, BMC I know are bigger than stock.  

It ain't much, but it is enough that the tech inspector will notice.

I'll agree that the performance difference is not what got him his lead, but his riding.

Then he didn't need to put in the filter, right? Kinda like the aluminum subframe argument "It doesn't really do anything" - then don't spend $$$ on one.

Everyone gets the same rulebook. The rules aren't perfect, but that's not an excuse to break them. We always check the rules at the beginning of the year to see what's changed.

it still could have been a warning of some sort. the rule is stupid. it should state "stock filters only" if that is going to be their stance. why can you not have a race filter if after market filters are allowed? it's not like it was an exclusive part.

[Eric Kelcher]

the line in the sand issue.

Why even require one at all? doesn't cost "anything" that way.  ::)

[THE_D.O.C.]

well mister official. why don't you just explain why one after market filter is ok, and one is not? same price, different dimensions. it's not like CCS is making a cost containment rule.hmmmmmm? ;)

[Super Dave]

It all has to do with the inlet size which ultimately determines how much air is let in.  Some aftermarket filters have a different filtering media that may allow for less restriction.  Some filters have a larger hole which will let in more air in addition to the different filtering media.  

So, I guess you have to think of the current air filter rules as a restrictor.  

I think that several years ago one just needed to have an air filter in the stock air box.

I think because in theory the whole point of "SuperSport" racing is that the machines should all be equally matched, and the rider should be the determining factor. You're not supposed to have a mechanical advantage over the other guy.

Of course, everyone tries creative ways to bend the rules... and in the AMA it's not even amusing anymore how much faster the factory "supersport" machines are compared to everyone else.

The fact is, I ordered a K&N Filter because I was under the impression aftermarket replacement filters were legal. K&N only offers (1) filter for an SV650 and thats the one I bought. Trust me when I say, if I thought for a second that CCS tech officials were so anal about K&N replacement filters I would have had the stock filter in place. I have no intentions of cheating to win, I don't have to. This was my first weekend on an SV650. I've never had this problem on any of my other bikes and had no reason to think I would this time.

don't worry about roach, JK. i've run into him on another BBS. apparently he knows every f&&%ing thing there is about racing. the fact is, there is NO REASON to out law an aftermarket filter in racing. unless the rule states "only O.E.M. filter can be used. STUPID STUPID STUPID!!!!!!!

Actually, DOC... I never claim to know "everything about racing", and I never imply that my personal opinions are "facts" as you state above in regard to filters.

So it would appear that you are the one claiming to know everything, including how the rules for CCS should and shouldn't be written, not I.

JK - wasn't implying you needed to "cheat" to win, was just trying to offer a guess as to why the rule is the way it is.

The issue is all about the air inlet hole size at the top. If you mic the stock verses the K&N, they are the same. The BMC is different. K&N filters are absolutely legal per Kevin Elliot if they measure out correctly. I went through this issue last year and heard many different opinions within CCS until I talked to Kevin. He even backed me up at tech at the ROC last year.
