    Hey guys,
    Was wondering if you could help me out. I'm looking to buy a used, low mileage 2013 Stelvio. The last 5 digits of the VIN are 12514. The information posted below was copied from the OP. I just assumed that the bike I'm looking at would have the roller tappets, but according to the information below, it's before 12596?...or was the OP referring to the serial number on the engine?

    Stelvio - AC - After AC12596 - 03/12/2012

    With a 2013 you should have roller tappets. There are some discrepancies but after serial number 12496 and build date of 03/12/2012 it should be fine.

    Yes, discrepancies. that motor # isn't exact. But around that time
    You can always look first to know for sure.

    Yeah...I don't think the guy would take kindly to me removing the valve covers...LOL. How can you find the build date?

    I would think removing a valve cover would be fine and considering the situation perfectly reasonable.
    My one fear would be that it is a 2012 titled as a 2013. That tends to happen in other countries more than it does in the USA. But it does happen, especially with a small brand like Guzzi.

    Would it help if I said the VIN was DM112514 ? Wouldn't the "D" clearly (on a cloudy day) indicate the rollers?

    You need to look at the engine number, stamped on the engine. THERE IS AN EXAMPLE ON PAGE 2 OF THIS FORUM TOPIC, halfway down the page.

    My initial inclination is that IT IS NOT a factory roller engine.

    "According to Piaggio, motorcycles produced after these specific Serial Numbers / Production Dates, have the implemented design change valve train, and are "roller" engines.

    Model - Engine Designation - Last 5 Digits of Serial Number - Date of Production

    Stelvio - AC - After AC12596 - 03/12/2012
    Griso - A8 - After 13524 - 04/12/2012
    Norge - AA - After 12214 - 04/18/2012"

    The letter D before the M (for Mandello) indicates the year of manufacture is 2013. Since this is later than 2012 you should be OK, but the only true test is to whip a valve cover off and have a peek of the followers.

    This just in...

    Turns out that what I didn't know, because I'm not sure it's totally clear in this thread...is that, the VIN is NOT the engine number. I'm sure most of you guys knew this, but I didn't.

    The ENGINE number of the bike I am interested in is AC013488. Fairly well beyond the AC12596.

    So just to be clear, it's NOT the last 5 digits of the VIN...it's the last 5 digits of the engine number.

    Correct me if I'm wrong.

    Thanks guys...learning all the time.

    You are correct. That is what I wrote and I'm sorry you missed it.

    I even listed the individual fields.

    Model and Engine Designation and Last 5 Digits of Serial Number and Date of Production. Not the VIN number. The VIN number is NOT the Engine Serial Number.

    Model - Engine Designation - Last 5 Digits of Serial Number - Date of Production

    Stelvio - AC - After AC12596 - 03/12/2012
    Griso - A8 - After 13524 - 04/12/2012
    Norge - AA - After 12214 - 04/18/2012


    Also, Adam Davis even posted a picture of the Engine Serial Number in this thread.

    Glad you understand now!

    So, go get the bike and enjoy the pleasure of owning a Stelvio!

    Yeah...my post number 50 was actually sent before I had a chance to read yours. It's all good. Road the bike home and just changed the oil and filter today. Used Castrol 10w-60...says it's for BMW M series...and a 551 Hiflo filter. Doing the CARC and gearbox tomorrow. Thanks!

    Hi, did you have any luck with this? I’m in a similar position. I’ve spoken with the ‘assistants’ at my nearest dealer and was looked at like I was stupid. I was speaking to desk muppets and not experienced mechanics. Their attitude was that as my bike didn’t have a full dealership service history then what do I expect. Whereas an experienced mechanic would know the issue...

    Some pics of mine.

    Any information or advice would be great?

    cheers,
    Ray.

    Hello,

    I’m sorry about your troubles but I’m not sure what you want.

    I stated it pretty clear. Bikes with a complete service history at a dealer were normally covered completely by Piaggio while other bikes were covered for parts.

    We are now many years out from the initial sale of these bikes and quite frankly, Piaggio doesn’t have to do a damn thing for free for anybody anymore. I suspect that they will not.

    I gather that your best bet would be to buy the kit and install it. Fix this problem and the bike is virtually bulletproof after this repair. Then you can ride the hell out of it for many thousands of miles.

    Good Luck!

    It really is worth it. It's not an easy job according to manual but once the bugs are out they stay out. It's a matter of personal preference regarding to performance mods. But outside of maintenance per manual my bike is expected to be a six figure milage machine. And I am approaching 50 years of life I would like to pass it down to my son some day. After all the big block production is over in Mandello.

    Wow, I just now looked at those pics. Ray, get a new cam cap, don't use that busted one. I'd also look for the piece missing. That wear all looks normal for needing rollers. If you took those off, you cam put new stuff on. Easey peasey.
