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.

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.

On-line OEM parts catalog

Pro Italia now has NTX parts on-line. I looked quickly and it looks like there is a comprehensive parts catalog that's easy to flip thru.

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.

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.

I recently noticed a clunking when moving along slow in first gear, and it almost sounded like the center stand banging. After checking it out and experimenting, it is actually from play somewhere in the drive. If I put the bike on the center stand and put it in 1st gear (engine off), I can rotate the rear tire and make the clunk as it goes from one end of the free play to the other (by rotating tire forward and back). So each time the drive train loads up I get the clunk. I am not sure how to measure this better, but the tire can rotate 2-1/4" at the outer circumference before hitting the stop each time I do it. That seems excessive to me, but I didn't check it when new and don't know if this is normal for this bike. The noise is not from anywhere near the rear wheel, more like the area of the transmission. Any thoughts?
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.
