ok, I caught Baggers post on this thread on the "noid mod" http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=290431&post=1118954#POST1118954 As soon as I saw the this; "...almost like I added an exhaust on the bike." I had to try it... Took it off this afternoon and went for 100+ miles and I'm in awe right now. The tone that comes from there is Amazing At 5k that puppy sounds ferocious. Stop and go traffic in the city was bringing huge grins to my face. I just can't believe how big of a difference it makes. We have a huge hill near my house that's about 1/2 mile from bottom to top and cruising up it at about 6k sounds like nothing I have ever heard before. I rode 120+ miles including both highway and city traffic. No engine codes, no odd temps and I just don't see any bad side effects. So, what am I missing here? What are the pitfalls of removing that cover? Is it really there just to reduce noise? Why haven't we all ripped that puppy out already? Its a great little taste of what the bike can sound like with an aftermarket exhaust. | ||

Now there goes the neighborhood, I wonder what it sounds like to a person on the side walk, hurt my ear when I wheelied because my head went down toward the front piece I removed from around the gas cap, I think everyone is going to do it now, see what I started. Mike | ||

I am stayin' way clear of this mod! Best of luck!  | ||

What are the pitfalls of removing that cover? Is it really there just to reduce noise? Why haven't we all ripped that puppy out already? As I understand it, and unlike the XB, the 1125R has a form of ram air induction for the airbox. If you remove the inner airbox cover you will actually lose power, especially at higher speeds, instead of gaining anything (except noise). I may be wrong, but I would like to see dyno results before and after to see what the difference is. | ||

I tried it for a day. Intakes are Effin loud, couldn't take it. It's back on to stay. Butt-dyno didn't see any difference. If you really want loud, just run the headers. Carry a rag with you to plug the pipes when you stop. Warped valves suck. Z | ||
| Nickcaro |
 wow, I can't imagine running just the headers... | ||
| Baggermike |
Trojan the dyno will not be able to tell because there would not be ram air intake on the dyno, I also removed the cover for another reason that has nothing to do with performance or noise, this is how I found out that it makes allot of noise. I would like to see if there is a difference on the dyno, I look at the throttle bodies then look at that hole for the air to come in and just does not look big enough or match the throttle bodies in size but you really can not tell by looking, I do like the XBRR ram air setup, I also do not think there is anyway to know if the ram air has an advantage over removing the cover at speed because of the fact the bike has to be going really fast to get any forced air into the air box.

If i remember right from my dreaded tech school days, ram air doesnt kick in until about 120 something miles an hour. But thats just using my memory. not 100% positive on that one. | ||
| Nickcaro |
Bagger, if you removed it for something other than noise and performance.... what did you remove it for? | ||
| Baggermike |
Hi Nick it is a top secret project. patent pending. when I am done I will post it. Mike | ||

So I took off the screws from my cover and got out on the highway. Got it up to 150mph and took off the cover and the air cleaner cover. Once the drag was reduced by having the covers remove me from the bike, the bike seemed to accelerate with the throttlemeister on. Sorry, that just popped in my head when I was reading above. I remember when I was growing up all the kids would turn their air cleaner covers upside down on their mom's chevy because it would sound so cool. It just sounded like you were going faster.

Hey Mike, are you still going to put that translucent air box cover on your bike and then put mood lights under it? | ||
| Nickcaro |
 aaaahhh, that may be it. Sign me up for one, I love the idea already. | ||
| Baggermike |
Bearly you know what happens to those who give away secrets? Nick yes but it is something better than just doing this. Mike | ||

>>>if you removed it for something other than noise and performance.... what did you remove it for? Dude. . . . if you can "hear the difference" you are likely in the process of sending your ECM into your the pool of problems to join your electrical gear. Let me guess? . . . next week commences the "gosh almighty my bike seems to run odd" thread. >>>>I look at the throttle bodies then look at that hole for the air to come in and just does not look big enough or match the throttle bodies in size but you really can not tell by looking, So the theory is that these guys from Berkeley and M.I.T just took a wild ass guess at how large to make the opening. You're killing me here. . .. | ||

+1 on what Court said. I'm tired of the "modding" then "issues" threads. I'm about to stop visiting the board and just enjoy my 1125R. The amount of actual good info on the 1125r board is beginning to pale in comparison to the complaining. (Message edited by jedipunk on April 14, 2008) | ||

Kind of guessing but knowing he ordered a Kick ash cover I am guessing some form of LED lighting to make the internals of the airbox visible? | ||

I get what everyones saying about people modding their bikes and then bitching about the problems they're having. That being said, I did take the airbox cover off after a friend of mine did it to his. (the same guy who got himself kicked off this board when he posted the mod to his exhaust). I know two other people who did this also. The result....NO problems with the bike or any codes popping up. I did notice a crisper throttle response and acceleration. I will put the cover back on and see if that was just my imagination or possibly the bike has been broken in now. Either way, if the ram air intake is for a boost, well, you dont get that effect until superlegal speeds, ergo, I need to experience it on a track. I'll let you know the difference between the two after a few rides. | ||

Air box, air filter, and exhaust mods are almost always the first thing done to most bikes and cars. Sometimes it helps and sometimes it hurts performance. I think that it`s great that everyone who has tried stuff is doing so and sharing their results / info. I do agree with Court though about some of the complaining. | ||

I WOULD SUSPECT THAT, AS THE SQUARE INCH OPENING OF THAT RAM AIR INTAKE IS OBVIOUSLY smaller than the throttle body size, that it does more for the EPA noise limits than it does for performance UNTIL you get enough airflow to create the pressure necessary to overcome said differnce. OF COURSE, the throttle bodies have to be pretty darn open to create a greater surface area than exists on the air intake, so for normal, and even spirited street ridng, does it REALLY make a difference? I'm all for more sound from the engine, it's performance and reliability that I am concerned with. Of course, perception IS a big part of performance... And, I am sorely tempted, indeed, if just to experience the full unadultered HONK of those intakes... As it stands, I think I may let you guys experiment a bit longer for me, before I go and try this one myself... | ||
| Court |
>>>Of course, perception IS a big part of performance... True be that. It was also one of the problems during the development of the 1125R. The power band is so flat, and the onset of power so linear, that it effectively "masked" the true acceleration of the bike. In fact the lack of a mid-range hit actually made the bike FEEL slower than the 1089. | ||

It just occurred to me that the intake air temp sensor is located at the front of the 'snorkel' y'all are trying to bypass. Could make your bikes run funky. Something to think about. Ya might be able to move it to keep the temp going to the ECM accurate so it adjusts fuel accordingly. I could be mistaken... JJ | ||
| Nickcaro |
well, I' don't believe that he snorkel is completely bypassed, but that is a good point. Here are some side effects that I have noticed after three days and 400+ miles. 1) everyday, without fail... If I started the bike with temps below 40 degrees, it would fire up and die a second later. Second attempt, it would fire up and stay running with no issues. Now with the innner cover removed; Yesterday was 35 and today was slightly below 30. Engine fired up on first try with no issues.... 2) has my MPG gone up? I'm squeezing an extra 15 -20 miles before the light comes on... 3) At a red light on 5th Ave. someone ran up to me waving. He said; "hey man, what did you do to this thing, it sounds like nothing like the other ones I've seen" | ||

Trojan the dyno will not be able to tell because there would not be ram air intake on the dyno, Most decent dynos these days have a very strong fan to simulate at least some speed (The one we use can simulate up to 100mph) simply because most sports bikes now have ram air as standard and need this facility on a static dyno for tuning purposes. Even with a small amount of ram air simulation you sjhould be able to see a diference between airbox on/airbox off on the dyno charts. | ||

Hi Nick sounds good that it is running better and sounding better, some people seemed to say it was a bad idea to do this but if you think about it what does almost everyone do? free breathing air filter and exhaust, I think more people have said bad things about removing the inner air box then adding a free flowing exhaust, or maybe I have not see the the post on them? Mike | ||
| 01xjbuell |
i remember on my XB12Ss I did the open airbox mod, basically replacing everything inside the airbox with a filter and cover to enclose it... this seems like a very similar mod, plus it seems most other manufacturers have similar concepts...? |
