I do not own a 1125 but I have been reading and have yet to find the answer to this question "What is the purpose of the active air solenoid & valve?". Can someone enlighten me? | ||
| Ccryder |
Short answer: It is to meet EPA noise/ emission requirements at a certain RPM where the testing is performed. | ||

YEP....WHAT HE SAID | ||

Closes the butterflies a little at WOT in 3rd gear when you open it up around 5000 rpm to meet EPA noise tests. | ||

To completely annoy the living hell out of all new 1125R owners.  Oh yea and +2 to what Ccryder said. | ||

I still need to do something with my bike. Every track day I do I normally get caught by that thing. | ||

Buell Part number Y0248.1AM resistor plug for the Active Air solenoid. you can just unplug the solenoid and plug it in. Don't have to do anything else. You can completely remove the solenoid and wire the TB if you want, but its a lot of work if you want to take the bike back in for warranty work to put it back on and off. resistor is like 7 bucks. you may get a CEL but the resitor makes it a historical so that it shouldn't come on after that first time. | ||

Does anyone actually have to reinstall the solenoid when going in for service? That would seriously suck... I think the dealer where I bought my bike went around and unhooked the solenoid on all their in-stock bikes after I told them about the $6 Buell part and the unfavorable effect the solenoid had when kicking in. | ||

I just did a full day at Thunderbolt Raceway and not once felt anything like what you guys describe. Not sure why not, because I know I haven't done a damned thing to my bike outside of new tires (for the track) and the first service at 620 miles. | ||

Ponti1 - I don't think many dealers would hastle you about it but if they for some goofy reason decided to follow the warranty to the letter they could actually void your entire warranty for this one installed part because if disables an EPA required device. Dumb, and I don't know any dealers that would do this, but piss off the wrong service writer or tech and bingo there you go no warranty. Jaimec - ride in 3rd gear hover around 3800 RPM and go WFO. | ||

I took mine off and the dealership didn't complain. It would be pretty horrible for a dealership to void a warranty due to installing a slip-on or 'denoiding'. | ||

Most dealers have no idea it is even there, so do not miss it. (Message edited by kttemplar on May 17, 2009) | ||

Bikejunky, I've been told that... and knowing that... why would you?? It's like the old joke: "Doctor, it hurts when I do this. So don't DO that!" Besides the 97 miles I did on the Thunderbolt Racetrack, and the over 4,000 miles I've put on the bike so far, I've not ONCE hit this problem. When I want to pass someone, I generally downshift once or twice FIRST, which puts me well beyond the rpm area where this happens (and I was told it was at 4,800 rpm, NOT 3,800 rpm). Someone once mentioned "What if it happens when you're in a turn?" and I can't help but wonder who whacks their throttle WIDE open when leaned over in a turn on the street? I always do a slow, steady roll on myself. So I can only come to the conclusion that my own riding style makes this issue a non-issue. Since it IS, in fact, happening to others, the only conclusion I can come to is that I don't ride like them (and they don't ride like me). | ||

I've got to say that the "de noiding" process is really simple, does not take long and the part is only $6. I don't see why a dealership would ever deny a warranty issue considering it is a buell factory part. Also, since installing it I have had zero issues with the bike bogging down when going wide open ... plus you can actually get full throttle once installed. With out the denoid the butterfly's do not open all the way. Correct me if I'm wrong, but in my mind that means you are losing performance. | ||

I would have to argue that they could not void your warranty. Buell sells the resistor part to anyone that wants one. It is not like the restricted "race only" parts that require a race license. So, how on earth would they justify voiding your warranty? From my perspective, unplugging the solenoid and installing the resistor is no more a warranty issue than installing the Buell heated hand grip kit. Both are altering the bike's original configuration by adding a factory-offered part. (Message edited by ponti1 on May 17, 2009) | ||

it's lawyer stuff anyway... | ||

Jaimec - had it happen in traffic before i knew about the condition and dern near got hit by an SUV that was trying to go around a turning car and through an intersection coming off of the interstate (I was going straight and did have the right of way). Yes I should have been more careful and watching traffic more attentively, but when I went for get out way mode the bike bogged and I came very close to getting hit where if no bog had been there I would have been easily out of the way rather than pulling vinyl out of my back side! So yes the bog is there we know about it, but sometimes it's not the I can avoid it argument, it's the Oh $h!t argument. honestly though unless traffic is stop and go ( and around here that is rare) I cruise above 4k RPM anyway so the condition doesn't really exist anymore for me either. | ||

The dealer or anyone else wouldn't have a clue (if they didn't alerady)...when removing the solenoid...remove the bracket also. Then there's no place to put the thing! I made a VERY simple little bracket to hold the air box/air box cover to the frame like the solenoid bracket did. No signs anything was ever there. Plus, the dealer where I bought mine...doesn't care either! Mike |
