also available: -2, +4 and +6 degrees

This rotor advances the timing +2 degrees. Increases part throttle power - what you'd call snap!
Decreases rotating engine mass - Lightest weight advance available.

For the 900's, it's the "suggested" advancer.

Other fixed advancers / retarders available, too.

That being said,  the "04" advance is a MUST DO with drop-in Erion cams in a stock engine, adding 1-2 True HP throughout the powerband. That's power measured under load - just like the Real World.

AND

If you are installing an AIrBox Plus kit, you'll get a nice chunk of additional midrange power with the airbox kit (+3 to +4 HP) - and if you use the +4 advancer, you'll get a nicer (stronger) boost at part throttle than the +2 will give - but - you'll only get +2 or +3 on top."

The best combination -  is the AirBox Plus Kit and the +4 advancer

...........................

I bought the RTR-HON-8-02 for my Honda CBR 900RR. This is simply the best thing and easiest thing I have ever done to my bike! Everybody I ride with wants to know what I did to make my 9RR so much more snappy in the mid range. And I gladly tell them about your timing advance kits. And next on my list is your evo shift kit! I was wondering if I could get some stickers to put on my track day plastics. If needed I can send a SASE to you. My address is Sylvia Kansas. Thank you very much!

Dear Factory Pro!!!,

Well what can I say, Thank you Thank you Thank you.
I recently fitted one of your kits to my Fireblade (CBR 900RRS 1995 model) it was like getting a new bike! I have had the bike for about 2 years now and I was starting to get bored with it, then on with the kit and what do you know its fun again. I fitted the +4° timing advancer, did the air box conversion and went with the 140 jets and the needle’s on the 3rd notch (down from top). It worked flawlessly, even with the standard pipe. I fitted a full race can (Art Full race) and the bike really purrs like a cat (a big one!) now.

Full details: ~

Honda CBR 900 RRS (1995 Irish market model)
Stock cam
Stock pipe
Art Full race can (Muffler?)
Filter ~Factory Pro 2*Unifilter (as in Kit)
Pilot~ Stock
Needle clips~ 3rd notch
Main Jet ~ #140.
Ave Temp.~ 10-15°C
Humidity ~40 to 60%
Altitude ~Sea Level.

Location~ Dublin, Ireland

Did all the work myself, it is no problem (I am an engineer by trade!).

I am now in the process of building a race bike, I hope to race the Irish Clubman’s Super Sport 400cc next season. The bike that I have is an NC-30 (VFR 400 R3N 1994 model) Honda, and I would like to know if you make jet kits, timing advancers and air box conversion kits for this bike, if you do can you give me the details and let me know how I can get one.

Yours gratefully,

Dave Reddy

Marc,
Just want to add to FJ's message. I got a CBR 9 this Spring with a full TBR and a Factory Jet kit. I have asked a few questions on the list and am more a lurker since I get the Digest and much of the mail is answered before I see it. However, I have always found your answers helpful and enjoy reading them. You helped me with my float setup and the list answers, including yours over the year, set my jetting up well according to my seat-of-the-pants dyno. So thank you for being so generous with your time and knowledge, all the best business wise in 1999 and have a merry Christmas.

Cheers, Ian
Subject: cbr900rr APK Airbox Plus Kit recommendation

Brian,

I had my 96 RR done with Two Bros full system, Air Box Plus kit, and put in 49 state cams. Stock CA, my 900 had 98hp on a Dynojet Dyno. After, it made 117hp, and unbelievably increased midrange. You will not believe the improvement!

Good luck,

Mikey Rosenblum

 
Subject: cbr900rr RTR-ADJ-HON-8 Adjustable Ignition Rotor setting

Marc,
I have the RTR-ADJ-HON-8 advancer set at 2 degrees of  retard. The guys at Marietta Motorsports here in Atlanta say that  seems to be the hot setup. What do you think?
Rob

Rob,
Umm, -2 on a silly dj dyno, maybe that works under that dyno's light load condition.  I suggest that you set it where it feels strongest to you in your  operating condition. Then do it -2 and try it. See what works best under real world load. Use that setting.
Marc
BTW - the guys at Marietta are pretty cool, but they need a Factory Pro EC997 Low Inertia 4 Gas Eddy Current dyno so they can help people even more!

Final:

Marc,
Final setting of +4 on the advancer. The minor loss at high RPM is offset by the Huge power anywhere else. Besides, I rarely run it to redline on the street.

Now that I've had some time to play, I've noticed that the bike inhales my friends' bikes at will. (except for that damned R1). And with the filters,  the motor sounds like it wants to suck the gas tank through the carbs in the process!!

Thanks again for your help!
Rob

Marc and Raul,

I just wanted to write you guys to say THANK YOU.
I ordered a shift kit for my '95 900RR and installed it with no problems. I thought.
When I started it up the engine made a horrible knocking sound. I sxxt a brick right then, I knew I fxxxxxd it up. The sound came from the head and the clutch. So after disassembly and reinstallation with no change I called Factory and talked to Raul.
He was very helpful and walked me through the steps to see where I want wrong. After two phone calls and return call back I realized that my screwdriver had been where is shouldn't have. When I first tried to take off the nut for the outer clutch basket I stuck my screwdriver into the crank/clutch gears to keep the clutch from spinning. BAD IDEA! I had bent the outside edge of a couple of teeth. I filled the offenders down and now she is better than new.

The shift kit works awesome. The feel is totally different and each shift seems solid. I know when it goes into gear.

Anyway, everyone has always been very helpful at Factory Pro.

Thank you.

Urban Myth:  a K&N Air Filter installed into a Honda CBR900 will lose power

my 2cents. no k&n
I read on? Erion's website, they tested the various, not the factory kit, aftermarket filters: They found that the factory filter flowed better or as good as all of them. This is true for my '95 I'm sure.
Other years no idea. I don't own one, so didn't pay attention to that detail.

Answer:

URBAN MYTH!! EXPLOSION!!! WHOOP! WHOOP! WHOOP!

CBR900 myth #1 (started by some "Honda race team"..... for some reason):
Hypothesis: K&N Air Filter doesn't make more power than a stock air filter.

The cbr900 K&N works just fine in the 900.

It takes 2 main jets larger than a stock air filter, 1 clip richer and a bit more fuel screw mixture. That's the total extent of it.
I think that it would be really hard to find somebody who had jetted their bike and had not made more power with the K&N or BMC filter.

The K&N (or BMC Race) filters flow somewhat more than stock, IF PROPERLY JETTED, make 1-2 more True HP than the stock air filter could.
Period.
The only thing that I can think is that they didn't properly jet the 900 after they installed the filter.
Say it's not true!!!  :-)

Background:
If the K&N did not decrease intake restriction, you wouldn't have to use larger jets just to get the fuel right again.
..........
Maybe we used a better dyno than a dynojet dyno to figure that out - or maybe we just rode the bike after putting in a K&N and said: "Damn! That's lean, Cartman! Let's put bigger main jets in it and raise the needle!" like one of the 2 guys who had one of two identical 900's did.
Low and behold! The 900 with the K&N and 2 sizes bigger mj's stomped on the previously equal 900.....

Reality is SUCH a harsh concept!     :=)

If best jetted stock air filter HP = X, then....
best jetted K&N/BMC HP = X+1 or X+2 HP, then
best jetted APK HP = X+3 or X+4 HP.

Marc, the pilot curmudgeon
:-)

Artisan Crafted Fine Cheeses – Since 1865       

Specializing in Handmade Brie & Camembert

Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.


 

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
Edited to the tunes of Chemical Residue by Herbie Hancock.




Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
