    I suspect it is normal. Mine has what I have always felt to be a lot of slop when doing what is described but after 70000Km it has not changed. I have never actually measured it. It was checked out by the dealer when nearly new and they said it was fine. (mines an 09)

    Ya know I heard the Guzzi Groan was normal too......I am throwing up the Bullshit flag on that one. I have been complaining since day one that my clutch didn't feel right. Big groan when starting off cold in the morning. fast forward 10 months and now that I have 15K on her she started throbbing thru the clutch handle and a distinct chirping coming on clutch release. Took into the shop and they are pulling the engine to check out the clutch and throw out bearing.
    I say when they say thats normal......well..... Bullshit.

    Mine hasn't been groaning recently (the 100-degree weather might have something to do with it), however there are some unhappy noises (from the starter clutch mechanism maybe?) on "cold" starts. :uhoh

    Mine has always had the occasional groan in the clutch. Seems to be more often in the cold. Bike has 40,000 miles on it, clutch still feels exactly the same.

    AF1 also has had the parts manual available for quite a while...

    I have noticed the clutch "groan" is very temperature sensitive. Mine groans severely when cold for many engagements until it warms up. It will do it even if I've been riding the bike for some time during the day, then stop, let it cool a bit, it will easily groan again until it's hot enough to stop. It does appear to have gotten worse as the miles pile up. I'm very soft on my clutches, I don't "dump" them or slip them unnecessarily. I can modulate the groan with release rate/rpm so I've learned to "ride around it", but I don't think it should exist to start with.

    I strongly believe the "groan" is a function of the clutch friction material, it's basically chatter. I've had this before on car clutches. When it's hot it works fine, when it's cold it works lousy. I don't know if Guzzi spec'd a different friction material for the Stelvio in expectation that it might be used in more demanding/hot conditions but I really don't like it. It's actually a bit unsafe if you aren't prepared for when it grabs.

    Has anybody been able to determine if the part# for the Stelvio clutch disc is different from other Guzzi models using the same engine, ie Norge or Griso?

    I'd be willing to tear mine apart and change the clutch disc if it solved the problem. I know it's a bear of a job, but I really dislike it immensely It makes the bike sound really horrible when it happens, nothing like the quality motorcycle it is.

    I can feel the "clunk" in the rear when I rotate the wheel slowly on the side stand, it feels like U-joints to me. I don't feel/hear anything while riding except that if you feather the clutch a slow speeds it will clunk (sounds like taking up slack) when you release the clutch. I can live with that.

    Mine makes that groan when it's cold. From what I've gathered, either TADT, or at least it's very common. I haven't seen a lot of people complaining about clutch failures or "chirping". I don't doubt that you may have a bad throwout bearing, but I think the "groan" and the "chirp" are different issues.

    Edit: I've learned that the various sounds that bikes make can drive you crazy if you're a little obsessive/compulsive like me. I have to remind myself that I've not yet heard a sound that caused my bike to explode or melt down. Again, this does not mean you don't have a problem with your clutch. It's just a bit of reflection on my part.

    Also, I have that "clunk" in my drivetrain, but I've decided to ignore it. My oilhead BMWs made similar sounds and I put more than 40,000 each on a couple of them with no problems.

    I groan when it's cold out too, especially in the morning. Normal? No...I'm certainly not normal, but, I've been going now for > 50 years so I'll just live with it. :lol3

    Chuck,

    My family goes to Bullys all the time but I haven't had the pleasure yet.

    It would be fun to know the name of the veteran you see, odds are I know him maybe a private message.

    On another note something I forgot to mention about my trip to Canada. I am at about 2400 miles. I have always liked the smoothness of the Guzzi and the mild "throb" but as I cruised at about 4k RPM looking at miles of green everything I suddenly felt the bike smooth out totally....like all of a sudden all the parts aligned and it has stayed that way. I know it takes time to break in machines, its just I have never felt one so suddenly improve.

    Sounds like the collective backlash of the drivetrain. As you get used to the bike you probably find you're exploiting the torque more and using lower revs, which on a big twin means you'll be at very low rpm at low speeds and the power will be swapping direction often (crank to wheel - wheel to crank) and each time the total drivetrain backlash is felt being taken up. There's a cardan joint to damp it a bit, but it's still going to be felt. It's fine though. Just try lifting the rpm more and using the clutch more.

    I just got home at midnight last night, after leaving late in the afternoon last saturday, from a quick 2700 mile blast from Texas to Minneapolis by way of the Badlands and Fargo using the winding roads feature of the new TomTom Rider.

    Damn I like this bike more and more, it's got a bit over 10k miles now and just runs better all the time. I left Sanborn Iowa yesterday morning a bit after 9 am and Tom did a really good job of routing me on some very minor roads that were a bit more interesting riding across the plains. At 950 miles, it added about 100 miles to the most direct route home but it did put me on quite a few roads I'd never been on before and they were isolated enough that I didn't have to worry about cops. Did you guys know the Stelvio has a sweet spot between 90 and 100 mph?:deal:evil

    I had gotten some requests for the dimensions of the studs I made.

    The finished length is 3" (75mm). The thread is 12mm x 1.75. These have about 1 1/4" of thread on them. They could be just a bit shorter, 2.5" (I'd use a 65mm bolt or just cut the longer bolt down more) would work and possibly make it slightly easier to slip the wheel out. I had to tilt the wheel at an angle to clear the fender while slipping it off the studs, but it worked fine.

    The screwdriver slot is very handy I I'd suggest spending the effort to put that in.

    The bolts I used were sourced at Lowes.
