Yes, there were three types of tappet fitted. But as I said, if you have the earlier type, they are covered under warranty.

I am in the process of purchasing a 2013 Stelvio and had the tech pull the head cover so I could see for myself if it had the roller tappets, it does.

there's a thermostat pre oil cooler so cold oil won't pass through the cooler unless the stat fails anyone replaced one? if oil warm up is a problem why the bigger cooler one later bikes?
34,000 Miles on my 2011 Stelvio, 1st tappets failed at 11,000 Miles, Been running like new ever since 22,000 on 2nd set, Not had rollers fitted. I trust the bike, My 2009 Stelvio did 19,000 befor I changed for the 2011 Model That bike never had any problems on any kind. Service it clean it Ride it and love it.

FYI,
Another difference between the flat tappet and roller tappet motors is the screw adjusters, adjuster nuts and rocker arms, flat tappets are course thread adjusters and the newer roller tappets use a very fine thread adjuster with an Allen head on the top end of the adjuster, be sure to note the difference before ordering spares, I got the wrong nuts ,now I'm waiting for the correct ones !!

Just got it firing!
Hi all - looking for a few pointers on this subject. I have a 2011 8v Norge which I bought June 2020 and it's been a bit 'clacky' on the RH pot since I bought it. I thought it probably just needed a bit of adjustment, and has been fine since buying it. Took it in for a service last week and the chaps were a bit alarmed re the noise. Perhaps it had got slightly worse over the year without me realising it. Then I found out about the flat tappet (possible) issue. It's done 42k. So - just needs a bit of tappet adjustment or more likely to be a roller-tappet replacement requirement?
