I installed mine this weekend. It sounds louder, but i have not ridden it due to it raining. I will take it out tonight if the weather holds.
K & N Air Filter Adapter
I just dropped the Rune of to have the K & N air filter installed.
I was wondering if anyone had already installed the device and if they noticed any difference.

I gotta burn up the full gas tank, then I will put mine on. (Im doing it myself) ken (12,201 miles)
Ready to roll
I have the Rune back equipped with the new air filter. I was charged $150.00, so I take for granted that relates to two hours labor.
There is a noticeable increase in the sound volume, but not significant enough to satisfy most of us who want to make a statement and frighten mothers and their children. I’ve only ridden it a mile and ½ so I can’t yet comment on performance. The Rune has always been responsive so if there is more horsepower I don’t know that I’ll be able to detect it.
I hope someone can report their experience relating to performance.
Proceeding on the assumption it takes two hours to remove and replace the tank, so as to change or clean the filter, the K & N Air Filter may, for me, be a bargain. I have neither the time no the inclination to perform this type of maintenance. The K & N lasts for 50,000 miles and after that you just clean and reinstall.

Hey Ken
Ken,
I didn't have to empty the tank to do this mod (mine was 3/4 full). You just need to pivot the tank up as described in the service manual.

It took me 2 hours (plus smoke breaks) to go from start to finish! So I saved $150. Since I have the Corbin faring, with that adjustment knob in the way, I opted for rotating the tank. I protected all my paint and chrome with Saran Wrap. Static Cling works great! I could manhandle the chrome side guards with my greasy mits, and not get finger prints on the chrome 
.
Note: is there supposed to be a missing gasket? there is no rubber gasket sealing the original filter housing from the intake manifold. there is a "channel" which looks like there should be one, and the service manual mentions "check sealing rubber." So, I just injected silicone dielectric gel in the channel, and greased up the brackets so air wont sneak by.
I noticed more sound, mostly when winding up the rpms. It is raining all day so I cant take the Rune out for a real fast spin. The first time I get to pass a semi on the interstate I will know if there is a difference.
Now that I see how it is done, I dont think I will worry about rain getting in. Besides, aircraft engines eat rain every day and still run.

My impressions of the Rune with the k&N adapter:
Sound- sounds louder, but not significantly more.
The people i normally ride with asked if i did something to the exhaust, they noticed it was louder.
During a hard exceleration, i can hear the air being "sucked" into the engine.
Power-Here is MY impressions, and some may not agree with me:
The power band has shifted farther up the RPM range. Since i don't have a tach, i cant say where exactly it is, but i definitely notice more response at higher speeds than before. riding steady and then accellerating with a Hard throttle at 60, 70 and 80 is more pronounced than without this mod. The low speed power seems to have lost a little response, but nothing significant. In fact, I don't have that "really sensitive" throttle that lurches forward when you hit a bump or hole, it seems to be more stable. Still has the quick excelleration at low speeds, just not the the overly sensitive throttle.
Feel- It bike feels different. There is a different vibration to the motor than before. Not rough, but you can "FEEL" the bike run, where before it was a smoother, more fluid feeling.
Overall, i would have to say it is a positve Mod, and i will keep it on the bike.

Gosh, with the modification the intake noise is really loud at 120+mph. The bike seems to take longer to get to 132mph than before --> when starting at 120 MPH :roll: . But: it is a whole lot more responsive from 60 - 110 MPH! I love it! I am checking fuel economy differences now. Yesterday, after getting the new rear tire, I was constantly hauling A** accellerating, playing with the filter, enjoying the intake noise. Usually, when I do that constant accelleration around traffic on the interstate I get about 32 mpg. Well, I got 36 mpg. Today, I am behaving myself on my 50 mile commute to/from work. I usually get 43 mpg driving like that. So, I will know this evening. The soot on the exhaust seems to be 1/3 the accumulation rate.
I agree with BigRed that at low speeds, the jerkiness of the throttle is tamed down, even when starting out with a cold engine.

Installed K&N
I installed the K&N last night and agree with the posts here. Sounds louder and much smoother at low end. Will be checking performance this weekend.

My mileage is now 15,600. So I have 3,400 miles on the K&N Filter Mod. A high speed run from SC to DC and Back, and some backwoods hauling around, plus the 100 mile/day commute to work all show that the modification is a good thing. The best feature continues to be the low rpm getting started when cold is no longer lurching and chugging. The response of the throttle is smoother. Intake noise is very satisfying when passing on the interstate. I think the noise also repels sex-starved deer from Hwy 78 at night. Or is it my lights?
Someone needs to dyno an unmodified Rune and post it under this subject string.

Air Filter
You are missing three important items.
Other rune owners need to know:
1. Where did you buy it?
2. How much?
3. Whats the part number?

(1) Above is where you can purchase one, if still available.
(2) The cost needs to be confirmed, but I think it is at or about $380.00 (+/-)
(3) It has no part number, as I recall.

Unfortunately that article only bashes K&N filters, and does not give actual NUMBERS. So, I will buy the first guy with a Rune who has a stock airbox to get his Rune Dynoed and then post the printout on the forum a beer!
Heck, I would settle for what the Max HP is and at what speed. Mine was 94hp at 110Mph. Ken(23,550 miles)
Then there was a magazine article on "bruiser cruisers". the dyno HP was 96hp at 110 Mph. So, given variances in accuracy between Dyno equipment, and, that I had the K&N adaptor in place, I think we see that
1: the KN filter did nothing bad or good for HP
2: the rear wheel HP of the Rune is about 95hp.
