I wonder how many owners are out there are blissfully unaware of this problem. Let's face it not everyone bothers with forums and Guzzi and it's dealers (present company excepted)) are certainly not advertising the fact. There also must be a few potential buyers going into dealers or on ebay this weekend looking for a used 8v Guzzi. The sellers will have their poker faces on and both fingers crossed behind their backs in anticipation of a sale and so the merry-go-round will turn for a while longer. I have not seen a bike advertised that states a roller conversion has been done with all relevant paperwork etc. etc. yet.
Gee don't blame the oil! Millions of flat tappet engines worldwide, old and new, continue to function every day. Many are brand new.
Ya know, that's kinda funny now that you mention it.Looking at this strictly from a financial standpoint, what's the difference between this and a Ducati?I mean we just paid $1200ish to service Jenn's bike and didn't blink an eye.

]Had the same issues with my griso suspension until recently when I took the time to set it up properly. It had way to much preload front and rear so I backed them off and set the dampening s right by the manual standard settings,they were way off as well, unbelievable difference. The roads here are terrible and I suffered way to long for lack of checking it out properly. The p.o. actually had the compression and rebound settings backwards. Also he was a lot heavier and must have cranked the preload front and rear. Have you tried adjusting yours at all?
I couldn't stand not knowing for sure. 2012 NTX purchased in October 2012
You are a very lucky person. Rollers. I bought mine at the same time and its flats.
I'm not sure why the GB owners club pulled their forum section that related to owners problems. I do know they got paranoid at one time about Piaggio UK because my threads on Guzzidiag mapping were pulled on the basis the moderator thought I was somehow in conflict with Piaggio's products. Mind you most of the members hadn't got their heads round the 1200 2v motor never mind a 8v.
Most notable is that Piaggio claim they do not "sell" motorcycles but only "promote" sales via a dealer network. Dealer goes out of business and that's your problem.Patrick HayesFremont CA
What is the difference? About 50 hp.
The difference is that that's a one time cost on the 8v's. It's a continual outlay for service for a Duc.
I am a member of the GB club. The current issue of their magazine, Gambalunga, has a two page spread regarding the lawsuit about premature cam and flat tappet wear on Stelvio. It is an interesting read. Most notable is that Piaggio claim they do not "sell" motorcycles but only "promote" sales via a dealer network.

Not to muddy the waters too much further, but that's only partially true.Just a valve and belt service on the Duc should be more like $600 max. And after the first two at 7500 and 15000 miles the interval these days is often 15,000 per.Meanwhile you still have to check valves on an 8V and if we're comparing factory service costs didn't someone here quote $400-500 for the Guzzi? Let's take $400 vs $600? That means you're only closing the gap by $200 each valve service. If you spend $1200 on the roller upgrade (I'm being conservative to be fair) that's 6 valve and belt services on the Duc.So you'll have to get to at least 45k+ miles (if you stick with 7500 intervals) or 75k miles (if you change to 15k intervals after the second adjustment) by the time the costs even out. THEN YES, in theory it's paid for on the 8V and remains a cost on the Duc. Except that you're only piling up $200 more expense every 15k so by 105k miles you've potentially only spent $400 more for that 50 hp.So one answer is $400 and 50 hp more.NOTHING is free and you have to pay to play.So pick your poison.I do agree with those saying that MG is going to get another black eye from this.Edit PS, I REALLY love Guzzi and prefer almost all their bikes over a Duc (of which there are literally very few that appeal to me, maybe just the Scramblers these days). So I'm surprised I'm making this financial argument. But at the same time I'm having a problem with Guzzi and these failures that just shouldn't happen (hydro's, dashes, tappets). Maybe part of the problem is such a low volume amplifies the significance of these stumbles.
Do the older air cooled Duc's have the same intervals, or are they similar to Guzzi for valve adjust?
OK - I found the cost of the upgrade package but my first question stands - can they all be "rollerised"? Thanks.
I'm utterly failing to find the How To to pull the tappet holder so I can inspect my tappets at the cam. Anybody got a link?
