If it flows any freer than the lean running junk they put on the bike stock you need to compensate.

Yes, you will need a tuner. No, it will not make your bike faster. It will however use more fuel and lighten your wallet by a considerable sum.

Which brings me back to all the research I've done, and just ask, why bother?

I’m not trying to get more power just the filter is about the same price as the k&n element but not cleanable but don’t want to put a tune in the bike and lower mpg anymore then it’s already

The K&N does a wonderful job of letting more air into the engine on the compression stroke. It does so, by doing an exceptionally poor job of actually filtering the incoming air. Independent tests have proved time and again that high-flo, reusable filters like the K&N fail miserably at their intended purpose. The result is a huge amount of small particle dirt and debris that gets stuck to vaporized oil from the filter, which then clogs your throttle body and intake runners. The mess isn't pretty. Save yourself the time, money and aggravation. Just stick with the OEM filter. Besides, the replacement interval is every 12,000 miles. Most motorcycles never SEE 12,000 miles in their lifetime before they get traded. By the time you replace the OEM with the K&N and install the necessary fuel processor, you'll have to buy a lifetime of OEM filters and then some.

On my last bike I had to change the filter every 8-10k do to the dirty sandy roads down here in Florida and put 80k on her before trading her in for this bike I ride a lot about 100 miles a day

Do the math. If you keep the bike for 80,000 miles then you are investing in 8 air filters. 8 times $35 is $280, which is still less than what you would spend for a K&N and a fuel processor. And the oem filters will do a substantially better job of filtering the dust, dirt and sand that you just mentioned. There is zero advantage to slapping a K&N in these bikes.

So. I think i am actually having this problem. I wish i had known about it beforehand this past winter, but i saw a few videos online and thought it was a good idea. :brick:
Thanks for posting the info.

I'm assuming that most of this same information would hold true with a Baron Big Air Kit. I had myself pretty much talked into the Big Air Kit, but now that I've dug a little deeper and read a lot of comments here, I don't think that the relatively small boost in horsepower is going to be a worthy tradeoff.

The Baron Big Air kit uses a K&N style filter. By the time you pay for the kit, the processor, the pipes and find a usable tune for the bike, you've spent a bunch of $$$ and gained all of 5 hp. Save your hard earned cash.

Yep, and that is the same conclusion that I came to. I already have Cobra pipes, but I would have to get the processor along with the kit since I am no longer running stock pipes. Just too much hassle and money to gain a small amount of hp. If additional power was that important to me, I would just buy a more powerful bike and be done with it. Plus, I've heard that the "sucking" sound from upgraded air kits can be kind of annoying. I'm going to just add that money to my custom paint job fund. :grin2:

The C50 is what it is. No matter how much money you throw at it you aren't going to gain much. Enjoy it for what it is, if not get something bigger.

K&N=fraud

I have used them, but no more. I read too many bad things about how they let a lot of fine dirt into the engine.
I have stayed with paper on all my vehicles.

A lot of race cars use them, yes-but those engines are torn down and rebuilt after they run a race. In those cases, K&N might make sense. Heck, some race engines might just window screen for a filter.

The only performance mods worth doing IMO are aftermarket pipes (for the sound only they wont change performance) and the C90 drive if you do a lot of highway miles/touring. Fuel processors are only worth it on bikes which are purposely massively detuned from the factory, and so upgrading the intake and fueling will net you noticeable gains, like pretty much all Harley Davidson models.
