Check out item #320260627456 on eBay - solenoid eliminator for the 1125. I didn't know that the AFV solenoid and harness weigh 777 grams, but they show it on a scale. The eliminator kit is a fraction of the weight, and eliminates codes to the ECM. Jack | ||

So has it been determined that this solenoid is strictly for noise emissions and can be safely removed. Is this the cause of the 4K RPM stumble? | ||

Well, I'm in. I purchased one. Markel Engineering is the same place that had all of the devices hooked up to the 1125r on one of the other posts here on the board. I would definitely like to eliminate the solenoid without throwing codes. In any event, I ordered one and will install it as soon as I get it and get a chance to install it. Mike | ||

BTW, Jpfive, thanks for the info! Mike | ||

NP, Mike. Looks like Martel is actively developing other stuff for the 1125 as well. There is some cool stuff on their web site. Fresno, you will have to judge for yourself whether or not the purpose of the solenoid has been established. I think that I will give the eliminator a try myself - the solenoid can always go back on if necessary. Jack | ||

From what I can tell, Markel Engineering has done quite a few interesting projects and I am willing to take a shot and see if this thing works. I also want to support them so that they make more cool stuff. Mike | ||

That's harsh, Peter. Sly's been working on this a while... | ||
| Interex2050 |
Zack you are right... I removed my previous post But $90 bucks is a bit much don't you think? Or at least a bit unfair... (Message edited by interex2050 on June 08, 2008) | ||

One problem with short run products is that the cost of R&D must be included in order to finance production of the product. If they charged less, they may not be able to continue to work on this and other projects for this bike. I for one, do not have the time to do it, so I would rather support them. $90 is a very reasonable price, based on the R&D I did not have to do and a finished (or mostly finished) product that I can just plug in and from which I can enjoy the results. Markel does not seem like a huge company and I am sure that they are not making much profit off this first run of 100 items. I would be surprised if they break even with such a low price point. Another consideration is supply and demand. I would purchase it for less somewhere else, but oh yeah, this is the only place to get it. I could just disconnect the solenoid as others have, but I would rather spend less than $100 for something that is probably going to work and not throw any codes. Your have a valid point, Interex, if I were to go out and put the item together myself at Radio Shack, but I neither have the time, equipment, or patience to do that and make sure it will work. Maybe, I am the only one, but I am more than happy with the price point. | ||

Mike, Your points are valid... I wish Markel Engineering the best of luck in developing more useful products. | ||

Fresno, Here is what the Electrical Diagnostics Manual says about the solenoid: "The active intake system uses a solenoid, which is connected to the throttle valve via a cable. The throttle valve is automatically CLOSED (emphasis mine) by the solenoid under certain conditions to reduce engine noise." The solenoid is discussed twice in the manual, with nearly identical text, and no reference to any other function. My experiences with solenoid operation is that it does indeed CLOSE the throttle when it activates. Granted, this has not happened often (thankfully) and is only momentary. But it is unsettling nonetheless. This is the one 'problem' discussed in this forum that I am not able to ride around when it happens, and which has the potential to put me in a hazardous situation. The eliminator seems an easy fix. Jack | ||

Something to think about: If you install one of these, will it void your warranty? I definitely would not take it to a dealer for service with it on there. So keep that 'noid handy. personally I think it's a great product, but you can accomplish the same thing (except for the weight savings) by just disconnecting the end of the 'noid cable, and leave the wiring attached to it. No codes, and easy to hook back up temporarily if you need service. 'Noid's Suck!  | ||
| Kttemplar |
Xb9 you have some interesting food for thought. Unfortunately,I do not think that the dealer is going to notice it is missing when I take it in for service. Maybe I'm wrong. I guess we will have to see. | ||
| Blazin_buell |
The shops I've been to wouldn't even notice if it was missing, unless it was throwing a code and their diag. tool told them what it was. Nice guys though!! | ||

I think I will go to Radio Shack and purchase my solenoid eliminator kit. A resister of the same value as the solenoid. I think this will fool the ecm and work just fine. | ||
| Ccryder |
Michael: Sounds like a great idea, glad you thought of it ;+} | ||
| Chevycummins |
Was going to try it a while ago but have been busy. I believe the ecm just does a circuit check through the solenoid to make sure it has the correct value as far as the electrical codes go. As far as the test it does using the tps and command close throttle, mine has not set a code yet and the cable has been disconnected for a while. Will try the resistor soon. | ||
| Cutty72 |
I unhooked the cable and called it good. I know that I am no where near fast enough of a rider to notice a weight drop of less than a pound. | ||
| Kttemplar |
Well, it looks like I am not the only one willing to pay for the convenience of just plugging it in and calling it a day. I looked on ebay and 4 of the 100 have been sold. I wonder if the rest of the people that bought them are racers looking for an edge or just lazy like me. | ||
| Nickcaro |
does anyone have any photos on where exactly to disconnect the cable? I don't mind the extra weight, I would just like to remove its function. | ||
| Fresnobuell |
777gms=1.7 pounds | ||

disconnect it at the throttle body under the airbox and rubber boot and tywrap the cable out of the way. tim | ||

Kttemplar, did you ever receive and install your solenoid eliminator? If so, do you notice any noticeable improvements? | ||
| Kttemplar |
I got it, but I have not installed it yet. I use my bike as my daily driver and I have not had the time to dig into it. | ||

From the Buell enthusiasts and Buell racing grapevine... Want to eliminate the active intake solenoid on your 1125R? Read on.  Buell is offering a module that plugs into the connector on the Buell 1125R wiring harness that will neutralize the active intake solenoid so that the check engine light will not illuminate continuously when the solenoid is removed. A brief check engine light will still appear, but only for the specific rpm range and throttle opening that engages the solenoid, and only for a few seconds. There will also be an associated stored error code, but no long-term light or anything else that would affect actual vehicle operation. The Buell part number for this module, just a small plug/adapter, is Y0248.1AM. Please note that this is a racing "off road use" only modification, which will cause any such modified Buell 1125R to fall short of the USA sound emissions standard by a small margin. Additionally, for qualified racers Buell will offer the PCM Tool and a “Race Use” ECM which allows disabling of the active intake solenoid in the ECM and its related diagnostics – so no check engine light related to this function would ever appear at all. That option however is only available through Buell race support, which requires valid current motorcycle road racing credentials. | ||

The Buell part number for this module, just a small plug/adapter, is Y0248.1AM. damn, $6 bucks for the thing. i might have to order me up one of those. | ||

Helicon, You motivated me to go out and tear into the bike and install that solenoid eliminator. It does exactly what it says it does. I just got back from doing a few mile test ride. The biggest thing for me was that it got rid of the "choking" at 3500-5000 rpm. Now, tooling along in third and gunning the throttle elicits immediate response as opposed to "maybe it will go or maybe it will choke out". The throttle response seems improved as well. The jerkiness at 3000-5000 rpm is still there, but it seems to have been reduced after removing the solenoid. One of the most valuable items that came with this product were the detailed step by step instructions that accompanied the solenoid eliminator. Markel Engineering is also extremely customer oriented and every time I have called, they have answered the phone and been there to discuss the product and installation. When I originally purchased the product I called them to get some more information about the installation procedure and they offered to walk through it with me step by step and tear down their bike to e-mail me pictures of everything if I needed it. It turns out that the instructions were detailed enough when I finally decided to do it today. It actually turned out to be a fairly simple procedure, but the instructions themselves and the superb customer service was worth the price of the product. If you are thinking about getting rid of the solenoid, then this is a great way to do it. Mike | ||

Thanks for the info Mike. Now I don't know what to do ... Buy the $6 product and have the engine light come on along with error codes, or pay $90 and not have to deal with that. $84 is a huge difference!!! |
