Hello All,
I was wondering if you guys might have some insight into an issue I’m having with my 2012 Griso 8V SE. Every time i start the bike cold it makes this rattling/scraping sound. It only happens at startup. Besides this sound the bike runs perfectly.
I’ve had it since march of last year and I’m the second owner. When i bought it there was 11,500 miles on it now it has 15,500. It does sleep outside but never uncovered. Something to keep in mind if and when the helpful suggestions start flying, I have a rudimentary understanding of how the bike works but I am by no means a capable machanic. I am planning on taking it into my local dealer but I wanted to check in with you guys and see if anyone has had a similar problem.
Here’s a recording of the sound…

Thanks in advance for any assistance.

Possibly a deep sleep induced thing, try keeping it awake, maybe leave a radio on under the cover.
Or it could be starter motor not releasing, button sticky in the cold ?

I have the same sound every cold start (Norge 8v)
Hasn't really bothered me I guess I have learned to live with it.

That's pretty good audio and I think what you are hearing is the sound of the bendix retracting after the starter relay cuts out after four seconds and the starter spins down.
I have no idea of what history of bikes you have but to me that sounds perfectly normal. Perhaps I should post up an audio of my great chunk of shit starting when it's hot! You'd poop yerself! ;D
Really though, that's just what they sound like. Once the chains wear a bit you also will get a brief rattle as the tensioners, that have bled down, take up the slack but on my bike this disappears within a second or so.
Stop worrying and remember it has a rev limiter so there isn o need to be easy with the go-handle.

That is only the sound of parts that are un-naturally dry of oil, pay it no mind.

Sounds Puurrfect to me ;-T

Sounds like a normal 8V rattletrap engine to me. Welcome to the Forum.

Nothing to worry about. I love Pete's descriptions of the sounds these bikes make, especially how his Griso with the open exhaust sounds at idle. Something like a hippopotamus gargling marbles.

Yep..

I wish my Stelvio was that quiet when it started. ;D
Sure sound let the starter bendix just spinning for a second when released. My EV and Stelvio both usually do that.
-
Sounds pretty much like mine too.
BTW, you do know to press and release the starter button right? Not press and hold like most other vehicles.
Strange that the Griso has a press and release button, but my Norge does not. It's a press and hold. (both are 8V).

It is completely normal, there are some minor things that can affect it. One is the speed at start, if it is low the starter drive may not clear itself from the flywheel teeth quickly. The drive is disengaged when the flywheel spins faster than the starter drive.Things like temperature ,engine tune, battery voltage, starter current draw etc. Not something you want to pay someone to try and fix as it's not really a defect,just an operating characteristic.

I think it was MCN that said that the 8V in the Stelvio sounded like a small diesel at idle, and after listening to mine they are right.

You guys are awesome and hilarious. Much appreciate the feedback. Whew, good to know it's not a big deal. I've only had the privilege of owning this bike since 03/2014 and it didn't start making this noise until it got cold here in middle TN (November-ish). Just wanted to make sure my baby wasn't suffering ;)
Thanks again everyone!

I have neither started, nor listened closely when near someone else starting one. Does the ECU control the starter, or why does one press & release the start button? That's sorta cute...

You do have a certain way with words Pete.... ;D ;D

I'd get hold of a car box or something and make a little house for it to sleep in.

The way it worked on the earlier bikes is that you touched the starter button and it triggered the relay to the starter. The ECU's logic dictated that if the engine hasn't started in four seconds it drops the relay out. Also if the crank speed exceeds 500rpm it also cuts the relay.
I think later bikes have returned to a more conventional press and hold system but they still kill the relay feed if the engine speed exceeds 500rpm.
