Going to do the open airbox mod this weekend and had a couple of ?s. I am going to cut down the stock box so when I re-route the breather hoses do they need to be seperated like the old tubers or can I tee them together with one filter? I am working on a drain line with a valve at the bottom of the chin fairing and I am going to use the breather hose as a catch can. I am also going to cut the snorkel. Now is this going to mess up the TPS as far as needing to be reset? Thanks Ken | ||

You should be fine running it at 3200(ish) rpm for 10 minutes or so for the ECM to relearn the new mods. Shawn | ||

You should be riding it, right? Not just running it in the garage at a high idle? | ||
| Metalstorm |
You definitely want to be "riding" it at 3200(ish) as stated above. Letting it run, parked in a garage at high idle is not recommended since it puts no load on the engine & there is a serious lack of cooling air rushing past the engine. | ||
| Lucky |
out of curiosity what happens if you dont run for ten minutes at 3200 and do you have to do that if you desnorkle or just for the air box mod. | ||

What happens is the ECM (chip) on the XBs "learns" as it is ridden. The point at which it does this is preset in the chip programming and it is 3200 RPMs. At that point the chip compares the air/fuel maps it currently has stored and compares it to the measurements it is getting from the various sensors. If there is a big enough difference then the ECM attempts to adjust for that difference to bring the bike back to a more optimal air/fuel map. If you don't do this then the bike may be "off" and not run the best that it can. If all you are doing is messing with the intake with no changes to the exhaust then you should be fine with the stock ECM. Just make the change and ride the bike at around 3200 RPMs. If you do more drastic changes to both intake/exhaust you should richen the mix with a race ECM or some other aftermarket fuel enrichener. I recently saw the benefits of this...had the Race ECM installed and the TPS reset. Went to ride it for the first time and it had a slight off idle stumble. Rode it steady for about 20 miles at 3200 RPM on a country road and it ran beautifully right after that...and has continued to do so since then. | ||

I noticed a lack of power since temp in my area is up to 95 degrees now, and airbox is so hot I almost can't touch it. Was thinking about blocking off "snorkel" and cutting up the airbox and cover. Figure blocking the snorkel would allow more air to cool the engine and less heat for intake. Makes sense to me  | ||

Blasterd, No probs with the mods you are thinking about. I set up a breather system just like you mentioned. There was some pretty good discussion on the subject. Try this: http://www.badweatherbikers.com/buell/messages/32777/115730.html?1116461979. If that dosen't work, look in the May 18th archives under " Here's the catch can part II" Enjoy! | ||

I have to say after reading about this mod and everything that is involved. It sounds to me like the kit from American Sportbike 9304 - 03-05 XB Open Airbox Conversion Kit $58.95 is a pretty darn good deal and addresses all of these questions. All you need to do is add either a catch can or a filter and you are good to go. The benefit of going the American Sportbike route is that it allows you to put your stock airbox back on, or if you have a 12 airbox, you could sell it someone with a 9 airbox and recoup some of the money | ||

At the risk of sounding silly, what is "desnorkeling"? Does it have something to do with the air intake. I live in Arizona and temps are already 110+ and climbing. Would this mod allow more cool air into the engine and increase power? | ||
| Ejiii |
The above listed mod is what you need to do if you install the American Sport Bike conversion kit and you want a drain tube/catch can to catch the crud coming out of the breather. The American Sport Bike set up has you run a hose with a filter on the end into the chin fairing and the crud just dumps out all over the muffler. There is a lot of water and other stuff. Pretty nasty. And to think all that gook is getting pulled into the engine with the stock configuration...yikes! | ||
| Blasterd |
Does anyone know if there is a catch can similiar to the Jaz catch can that can be tucked away somewhere on the Cityx? Norris' is very nice but I can't swing it right now. I had a Jaz on my Cyclone and it worked great. Ken | ||

Blasterd, looking at your profile you have an M2? Is this just a stealth advertising campaign for the norris catch can?  blastered = norris? | ||
| Elff |
Wouldnt The CityX location should be identical to the Firebolt location in all of the pics in that thread | ||
| Blasterd |
Fogal, I have not updated my profile yet but I sold the M2 and bought a CityX. I was just curious if anyone put a Jaz on an XB. Thanks for the info everyone! I have a great idea on how I am going to set the airbox (or lack thereof) up. Ken | ||

Having had an S2 and a XB, here is my story. The catch can is a pain in the arse. You might be different, but I always forgot to drain the dumb thing. Cache can worked great, but if you put some miles on it be prepared to drain it more than often. I left my puke oil going back to the intake. Fewer hassles that way. Not worth the 3HP increase, in my opinion. The airbox mod is good if you want your xb9 to rev faster. I have the 12 box on the 9. Did a 2 1/2 inch hole saw everywhere possible on the 9 airbox. Not much improvement in torque. Torque seem flat. Cut off the air horn. Another improvement in revving faster. Conclusion: increase the air and fuel capacity for increase performance. Improvement with the race ECM and a pipe. Found out also that the more air one can shove down the throttle body, the faster it revs (thinking about the 12 Throttle Body on a 9). A little more torque for wheelies in the low RPM range. My 2 cents. | ||

That's why I used a clear tube instead of a catch can on my CityX. You can instantly see the water/snot level and drain accordingly. You never have to think about it because it's always visible. I get to keep my 3 H.P., have an easily drainable system and because it's visible, you can't forget!

Ejiii, is there any mods I need to do to my bike since I put the CF Air Box w/Ram Air snorkels on? | ||
| Buellboy05 |
ok, someone correct me if I am wrong but couldn't a person just run both those breather hoses, connected or not, out the bottom or back of the bike and not worry about the hassle of remembering to drain it or spending money on a catch can. do something like a T fitting with the two hoses to another hose out the back. Good or bad idea, and why? | ||
| Kaese |
That oil puke always manages to find a way to get onto everything. Hope you enjoy cleaning your bike much more than you do now. | ||
| Wheelsleaning |
Buellboy: As far as I know it's illegal, especially for track days. And Kaese is right, no matter where you run that drain hose, it will get on your bike.  | ||
| Elff |
Think if it from a safety point of view That gook dripping down could cause a tire slip and crash if it isnt caught. | ||
| Ejiii |
Under certain engine operating conditions a vacuum may be present in the hose. Contaminants can be drawn into the engine so you really should run a filter in the system. If the filter gets saturated with gook it's like flinging a soaked sponge around and is messier than an open line. The set up I use has a plug in the drain hose so the gook is trapped until you drain it out. That's why the catch cans have drains on them as well. I gotta tell you, there is a lot of crud that comes out of the engine. I can't believe they let that stuff recycle back in emission controls or not! | ||
| Blasterd |
Ejiii, I rerouted my breathers today and used a similar setup as you except nobody in town had any 3/8 id clear hose in stock, but I can get that later. I wanted to run this by you though. I tee'd off the breather hoses and ran one down like you said except I ran it a little longer, down to the top of the voltage regulator and then ran the filter line back up the side of the jugs, in between them and straight up through the top of the airbox base (it comes up right beside the coil). Will the jugs get so hot will they melt the breather hose? Will there be enough hose for gook to fill up? The "collection line" is only about 6-8 inches long. I started cutting up the airbox cover but did not finish. I am cutting about an inch around the bottom of the cover where it snaps all the way around the lid except for where the snorkel intake is, I cut a "wind deflector" pointing toward the filter. I am going to use the stock filter holder as the lid. And I did de-snorkel it too. What do you think guys? Ken | ||
| Ejiii |
Blastered, Sounds like you should be OK on the hose routing. Most of the PCV hose out there is pretty hi temp so I don't think you will have a melting problem. Time will tell. I can tell you this, I had about 5" of water in the drain tube after about 100 commuting miles so it looks like I'll be draining weekly. I'm amazed how fast it fills up. To think all that trash was going into the engine! Depending on how far you ride you may need to make the drain line longer. Keep us posted on how your system works out. E. J. | ||

i am thinking about attempting this mod but i was wondering what kind of performance change is everyone getting from it. i seen some one refer to a 3 hp change. can you tell a difference in the performance? | ||
| Ejiii |
I'm not sure if you can tell a performance difference or not. The reason I did this mod on my bike is because I installed the American Sport Bike air box eliminator. The holes in the air cleaner base, where the stock breather hoses are routed to, are used to secure the new lid on the air cleaner. The PCV system has to be routed elsewhere. I will be installing the F.A.S.T. intake system in the very near future which also requires the PCV system to be rerouted so I'm all set. I can install the F.A.S.T. system in about 10 mins. and ride. | ||
| Lucky |
sorry i should of been more specific i was referring to what performance changes do you get from the air box eliminator and the breather hoses and if i did that would i have to get a power commander to adjust the fuel map, all i have now is the race kit. | ||
| Ejiii |
Well, more air and fuel equal more power. How much more with the American Sport Bike set up I don't know. The F.A.S.T. system has an independently documented 6hp gain (using race ecm and a free flowing muffler). The breathers have to be rerouted either way you go so any hp gains from that are icing on the cake. You won't need any PC's or anything like that. I just reset my A/F ratio with the TechnoResearch software then rode the bike at 3500rpm for 10 miles so the ecm could "learn" the new setup and everything was fine. My bike runs strong. |
