    I installed the beautiful GT-Rx CNC cut aluminum airbox cover on my ‘08 1200S this past weekend. When I (finally) got the tank off and took the plastic plenum cover off, here’s what I saw:

    Say what?

    B42B0312-8FC3-467D-AEF5-05A8BB3717AE.jpeg

    Thoughts on how this happened? I have had mice load up a motorbike muffler with seeds and nuts over the winter before, which was impressive enough as the muffler was about 10”off the ground.

    But is this rodent work, or some set of perfect conditions where this specific type of seed got caught up into the air scoop while I blissfully rode along and were deposited as seen here?

    Here’s what I resorted to so that I could disconnect the fuel line and remove the tank. It’s the only thing that worked for me.

    0D3BD888-6F71-4867-9478-D590139B1F32.jpeg

    The instructions that describe how to get this thing apart say that one pushes the hose end of the connector toward the tank outlet, while pulling back on the gray disk thing at the same time. I was not able to do it.

    The connector appears to be constructed to accept a tool. So I kind of constructed one, using two (Park) bicycle wrenches (11mm & 14mm), a scrap piece of 3/4” pine, and a small pair of Vice Grips. With this all in place I Could just wiggle the thing a bit while pulling back and off.

    Lastly, here is the new airbox cover in place with hi-flow BNC air filter. I wanted to ask whether there is any problem with my routing of the crankcase vent tube, seen here zip tied to the top.

    I think that tube is the gearbox breather, trace it's origin to prove me wrong. It doesn't need to "feed" the injectors, but should be located somewhere under the tank and be connected to nothing.

    Before you refit the fuel line, try smearing a little petroleum jelly or dielectric grease over the male part. Should make it easier next time.

    If you didn't remove fuel pressure that connector is a bugger to get disconnected and the "tools" made it possible. Next time disconnect teh fuel pump and attempt to start. The line comes off relatively easy if you do that. As to the seeds, mice will go everywhere. I found mouse nests in the valve chamber of my 1926 Ford Model T when I started the restoration.

    Dave, thanks for your comments and I did use petro jelly last time and so was a bit surprised as the last (first) time I removed the tank the connector came off much easier.

    You know John, I forgot all about relieving the fuel line pressure. Ugh.

    Might be a bit blonde here but maybe an easier or cheaper solution here might be to put fair sized washers under the original screws to hold the middle airfilter plate on- negating the need to purchase the aluminium part. My airfilter box was full of the foam you can see on the middle plate- mine disintegrated. :( You would have to drill to suit the sensor though.

    Sure. So noted as to why I won't be doing another run of these once my stock is depleted. Just make sure you fix the fueling if you do this mod.

    Just back from our first two-up ride with Todd's full fueling package. Others here have described the results and so I will not list all of the same benefits that we're also seeing.

    I am not sure I can do this justice, but what came to mind out on the road was...

    "My will, incarnate"

    I am now starting to send Autotune results (Trim screen shots) to Todd after extended rides for his review and adjustments. But the base map he provided (setup based on the add-ons in place now, and his experience) must be close because I can see post-ride that Autotune is only making minor adjustments. After doing some research into how PC and Autotune work, when I read the new maps I feel like I'm "reading the Mind of Todd". :cool:

    I am very pleased with the results. My wife thought the change, "incredible" and that, "this is a totally different bike".

    Thank you Todd.

    airbox.JPG airbox screen.jpg Yeah, here in the great Northeast it gets mighty cold and them poor mice seek shelter just like we do. My Sport (and my KTM) had a similar problem last spring, even worse than yours. I service my bikes in the fall, and they are usually ready to go with dropping the battery in and sometimes gas. The Guzzi started but ran like S***. Removed the tank and was horrified. With my KTM I figured to just remove the seat for the winter, and the airbox wouldn't provide "shelter", but not really easy with the Guzzi. I needed something more, and this is what I came up with, using materials at hand. I suppose if Iv'e pissed off the mice, they could always poop in the airbox but they can't get in.

    Great post and nice pictures! I am looking forward to installing the airbox lid on my Norge soon. I recently added some auxiliary lights and wanted to remove the tank to run the wiring. Maybe I got lucky, but the fuel connector came off on my first try, with no tools and without relieving fuel pressure. The bike had been sitting for two days, so that may have had the effect of lowering the FP. I basically mimicked the motion to remove an air hose quick disconnect. It was a bit of a surprise, as I neither heard nor felt anything to let me know the line was free. I simply pushed the female connector toward the male elbow, then pulled the collar in the opposite direction, and then pulled on the line and it slid right off of the elbow. With the line separated, I tried to study the female connector to see how it worked but I couldn't figure it out. I'm guessing the flare on the male end causes the prongs in the connector to engage the flare, but the movement of the prongs can't be duplicated by just moving the collar when the male connector is not there.

    Another thing that plugs up filter is the foam pad coming off of underside of tank, it deteriorates and goes in even w/stock snorkels. I replace the foam w/Aprilia's foil stuff that is under their tanks.

    The foam underneath my tank is not deteriorating, but some of it has peeled away from the tank. I was tempted to rip it off but decided not to just yet. Does anyone know what the purpose of the foam is? If it's for sound deadening, I don't need it. If it's to insulate the tank from heat, I might try some tape of glue to stick the loose sections back on.

    I've got these, used them once on a frozen connection. Not normally required.
