Where is this noid? Not sure, between the cylinders near the throttle bodies. It's on the right rear of the air box, near the TB What does it do? At very specific engine speed and throttle openings it closes in order to reduce noise from the intake. Stupid EPA. Yep closes the butterflies to reduce engine noise. Why do owners remove it? To eliminate complexity, reduce weight, and avoid the loss of power. Yep, yep, and most of all to eliminate the possibility of the solenoid closing the throttle at a VERY bad time What are the benefits of removing it? See above. What are the down sides? None. Does it void the warranty? No. What does the "plug" do? It stands in place of the solenoid actuator so that the ECM doesn't know the difference and thus doesn't report an error. An error (Check Engine Light) can still happen if you meet the scenario that actuates the solenoid since the ECM double checks to see if the solenoid actuates by monitoring the TPS to see that the butterflies closed. The error will be cleared when you cycle the ignition key If I were to de-noid my bike, where can I get the plug and how much is it? It's an off-road only part I think and is available from your dealership. Yep it is a Dealer part about $6.00 and change. I don't know if it's marked "Off road use only". That's my story and I'm sticking to it ;+} Later all Neil S. BTW, Blake you do pretty good for just reading what's going on with the 1125. We really do need to get you on an 1125. | ||

I would think by now, I would have met the parameters for activation at least once in that time.} | ||

Thanks Blake/CC, those were the answers I had in mind, but wasn't sure if I was absolutely right...Makes allot of sense... Want to apologize to everyone else for bringing up something thats probably been around since day one...i'm a tab bit lazy and don't have much time for myself to do the search...but thanks any way, i understand... Thanks everyone much appreciated! | ||

Fresno, the plug does NOT prevent the CEL if the correct conditions are met. I've tested it on purpose & can make my CEL light up "on demand" repeatedly. The CEL & error clear at the next clean start, so nothing to really worry about with it though. For those who haven't experienced the noid in action, or would like to check the results of their "noidectomy", follow these steps: 1) 3rd gear 2) ~45 mph/~4,850 rpm 3) Go WOT as fast as you can If the noid is installed & working, you'll get a "failure to accelerate". If the noid has been disabled, you should get the CEL. | ||

Harlan, Harlan just follow Phil's instructions above and if you go WFO as fast as you can, you will have that CEL stare back at you. Like I said before, I can do it on command anytime I want, even when I don't want it. Since it's disconnected, it's just a small PITA. Time4Sleep | ||
| Eaton_corners |
Just curious,but if you still get a CEL with the resistor, whats the point in spending 6 bucks? Since weight is not a primary concern with mine, I simply removed the cable and left the solenoid plugged in. | ||
| Zac4mac |
That's what I did Eaton. I have had the noid kick in once, pulled the cable 30 minutes later. Since then I've seen the CEL once. Glad the cable was gone that time... Z | ||
| Samcol |
I pulled the noid and put the buell chip on. I still get the CEL error every now and then, but I don't get the lack of power that I had when the solenoid was still in. | ||
| P_squared |
The resistor is to prevent the error code you'd get if it wasn't there. The ECM is looking for 2 things (that we know of) when it instructs the noid to activate: 1) TPS readings indicated the butterflies closed 2) Electrical continuity to the noid itself so it knows it's receiving the signal. The resistor, as far as I know, addresses #2. It makes the ECM think the noid is still there & connected. That's probably a good thing on an ECM that is programmed to comply with EPA regs, no? | ||
| Samcol |
I have the resistor and the CEL still gets tripped when you nail it in 3rd gear at times (although it might happen in other gears as well). | ||
| Jaimec |
So let me understand this... The "failure to accelerate" condition can ONLY happen in 3rd gear? And if you whack the throttle wide open instead of simply rolling on the throttle (proper MSF technique)? Might explain why, in over 7,000 miles, I only experienced it ONCE and that was when I was attempting to "misbehave." Under normal conditions, when I accelerate, I roll the throttle, I don't smack it open. And in traffic situations, I find the handlebars and/or the brakes to be far more effective "accident avoidance" tools. Just me. YMMV, of course. | ||
| Ccryder |
Yep only in 3rd gear and you have to go WFO as fast as possible. Most people don't use the throttle to avoid an accident. A far better accident avoidance tool is thinking ahead. It's even more effective than brakes or handlebars but, that's a whole new topic. ;+} | ||

The Noid is described as an EPA Noise emissions addition. It is designed to limit the amount of noise coming from the intake in order to keep the bike within EPA limits for noise pollution. It actuates only under certain conditions that would create a noise emissions violation. Likely that third gear WFO causes the bike to produce too much noise when combined with the sound coming from the exhaust, and transmission and engine. Some have also speculated that the exhaust pointed to the rear wheel is to break up sound in order to pass EPA Noise requirements as well. | ||

Jaimec, you've got it correct. Now you see why I stay out of the debate on if this is a "safety issue" as delivered from the factory. As a sidenote, and YMMV, I do recommend a 'noidectomy before a trackday. Coming out of a 3rd gear sweeper and trying to get on the throttle fast only to have a "failure to accelerate" can be a little disconcerting. I blame it all on that sneaky flat torque curve! | ||
| Chadhargis |
I will vote with the safety issue camp. You are supposed to be under power in a turn to settle the bikes suspension. At a big lean angle, having the bike suddenly cut power can disrupt the chassis enough to cause a crash. And having the power kick back in abruptly is also a concern. Thankfully, Buell took measures to make it easy to remove. | ||
| Geforce |
Amen! And it is very simple to do. With all the 'noids laying around I wonder if we could smelt them down into something usable... Like some cool Buell 'noid wheel stands... | ||
| Fresnobuell |
Most people don't use the throttle to avoid an accident. I like to get off the gas and stay mired in cager cluster-f. j/k. But I personally have used the throttle on countless occasions to escape sticky situations. Now that may not mean whacking WFO, but to me it's better to escape and get out front in circumstances. | ||
| P_squared |
Chad, what you're stating doesn't make sense to me? Why would a person whack the throttle while leaned over (unless they're intentionally trying to spin the rear, which is admittedly above my skill level)? With the exception of trying to spin the rear, it's more likely the 'noid kicks in after the apex when you're getting on the gas and bringing the bike up, isn't it? If that's the case, intentionally spinning the rear, I can see the safety concerns on track. If folks are intentionally spinning the rear on the street and therefore think it's a safety issue in that light, I'd rather stay far away from them. I can see the safety issue angle on the street for folks who want to merge with traffic & need to go NOW, but the counter to that is riding less aggressively. Just my opinion, but I think a person's riding style has a lot to do with if this is a safety issue or isn't. BTW, not trying to start a flamewar/heated debate with either side of the 'noid/"safety issue" here, I'm just asking for someone else's perspective, so don't crucify & pillory me please.  | ||
| Chadhargis |
On my bike, you don't have to go WOT to activate the solenoid. I had it happen to me twice while hitting the apex of the turn as I was getting hard on the throttle. Maybe it's my riding style, but I had it activate quite a lot, and I only rode the bike for maybe 150 miles before I yanked it. I went to pass a car, and it cut out on me...that sucked too. I'm thankful Buell has made it easy to bypass. Buying a 146hp sportbike and riding less aggressively seems counterintuitive.  | ||
| P_squared |
On my bike, you don't have to go WOT to activate the solenoid. That explains it in VERY clear terms for me. Thanks. | ||
| Chadhargis |
Yeah...it's more like how fast you roll on the throttle. I can be at a very light throttle opening, then quickly feed it quarter throttle at the magic 5000rpm mark in 3rd gear and it's like someone hit me on the back with a 2x4. Bike just QUITS. You can keep on rolling the throttle and it does no good. As soon as the RPMs drop out of the range, you better hope you aren't at WOT, because then it comes on with a vengeance. Again...thanks to Buell for making it so easy to remove! I know why they did it, and I'd rather have the solenoid solution versus a throttle by wire type arrangement. | ||
| Jaimec |
I guess my throttle roll-ons are just naturally smoother than you guys.  Did 92 miles on the track during Superbike School last May and never once tripped the condition. | ||
| Jdugger |
> Did 92 miles on the track during Superbike School last May and never once tripped the condition. Depends on rider and track, too. I hit it several times at Cresson, but never at Eagles Canyon. As I got faster as Cresson, I saw it less and less. For me, though, the big upside is the reduction in the throttle springs... OMG they are so much lighter now! | ||
| Blake |
>>>it's like someone hit me on the back with a 2x4. Of course you know, you probably deserve that. | ||
| Chadhargis |
Yeah...it was probably the hand of God. | ||
| Jaimec |
The smoother you get, the faster you get. Makes sense you felt it less as you got faster. But I just realized there IS a valid reason to remove the 'noid. If I want to wheelie past a red light camera, it wouldn't do to have it fall flat on its face in the middle of the intersection, would it?  | ||
| R2s |
I wish the throttle was lighter still. | ||

I have the resistor. Went to 4800rpm in 3rd and went WOT instantly. No CEL. ac |
