Title: Griso 8V 15K Miles
Post by: Griso8V on December 28, 2018, 06:55:27 PM
Today my Griso 8V turned 15k miles.  It is a 2010; not that many miles but just wish to report that these have been 15,000 flawless and trouble fee miles.  I have done everything wrong to this bike according to many on the various forums, these wrongs include:
1.  Following the manufacturers oil changing interval guidelines
2.  Using recommended weight oil, any brand.
3.  No oil analysis, ever.
4.  Using it for short trips.
5.  Using it for short trips in cold weather.
6.  Using the motor in any rev range. 
7.  Maintainance performed by the dealer. 
8.  Many more abuses that I can't remember.
So, anyone who is hand wringing about the reliability of the 8 valve motor:  Sleep easy!

I bought my Griso new from Pete Roper in 2013. It had its 1500km service (done by Pete) and then its 10,000km (done by Motociclio in Sydney) and then I moved back to Geelong and was too poor to have the bike serviced regularly. The next service and oil change it got was at 60,000km. I was still poor and it didn't get a service until I was able to access my superannuation at 104,000km. I took it to Pete and he treated it to new rings and valves and a lot of other stuff, but he was surprised how good the motor was considering the way it had been "looked after". It has now done 145,000km and is still pulling like a train and still great fun to ride.

Unfortunately despite the fact that it's not showing any outward signs it is failing. If you pull a cambox and examine the tappets it will be very unlikely to not be showing damage by 15,000 miles. All flat tappet 8V's will fail. To believe otherwise flies in the face of all evidence to the contrary. Sorry.

Yes, yes, a ticking time bomb! But then again, I like to live dangerously.  I guess if I live long enough I will fail too...

That's fine. It's just a terrible waste of a wonderful bike. When it does start rattling please don't just close the valve lash up and flick pass it to someone else.

Post by: pete roper on December 28, 2018, 08:36:34 PM
The only 'Big deal' as far as I'm concerned is the fact that nobody wants to hear that they have bought a turd. Therefore people generally will seek out what they want to hear and in the case of flat tappet 8V's what they want to hear is that the problem doesn't exist or at least is greatly overblown.

I had this happen a year or so ago, I think on the Ghetto? Some pommy bloke showed up with an 8V 1200 Sport and I suggested that he get the top end inspected because it was going to fail. Anyway he went to his dealer who told him the issue was very rare and he didn't need to bother and he then told me I was talking out of my arse and buggered off with lots of references to my ancestry etc. etc.

Once again the situation was that his bike wasn't showing any outward signs and therefore, basing his argument on his extensive experience of one bike, his, and without actually bothering to do the small amount of work necessary to confirm whether there was damage or not he chose to believe what he wanted to hear, the sort of equivalent of sticking one's fingers in one's ears and saying "LA-LA-LA" very loudly.

The thing is as soon as I started seeing failures in my shop I started inspecting every bike that came through the door. Ones I'd serviced from new, one's from other shops, ones bought to me because their shops assured them there was 'No Problem' but they were skeptical. I haven't seen one solitary engine with over 20,000km that didn't show wear. That is a 100% failure rate. Often they've had serious damage well before that 20,000km point!

The thing is until all the DLC has been abraded off the tappet there are few outward signs. Valve clearances change little if at all, there are no warning noises. The one thing that is usually noticeable is the the engine oil tends to get blacker a lot quicker and may smell appreciably more *Burnt* as the DLC degrades but all the time the particulate matter is being fed through the engine and may be causing further, terminal, damage. I've had about a 3-4% post rollerisation failure rate of big ends and main bearings and that seems to be directly related to the higher the mileage covered prior to rollerisation. Annoyingly it isn't consistent though! My Stelvio which ai rollerised at 108,000 km had had TWO sets of flats through it and it never went tits! My first Griso motor was rollerised at about 80,000 km and the bottom end went tits about 6.5k later?? Go figure!

My experience and research is based not just on one or two or even a handful of 8V's. It's based on quite literally hundreds! It seems like every 8V orphan on the east coast of Oz eventually wanders into my workshop and I've completed well over 100 rollerisations, I stopped counting at about a hundred. I think I'm probably closing in on 140-150 by now! Do I get some sort of perverse pleasure from telling people that their bikes are in the process of shitting themselves? Of course not! But I do enjoy trying to save as many of them as possible as I think the CARC series bikes are magnificent and worthy of saving!

When I was still an 'Official' service agent and was slapping in warranty claim after warranty claim on failed engines I was asked by the warranty bloke at the importer why I did more "By an order of magnitude" than any other shop in Oz. The answer is simple. Because I LOOK for the damage because I know it's happening. Nowadays I'm freelance again but I'm still doing rollerisations at the rate of a couple a month. Most of these bikes are at least seven years old now and tend not to have full service histories so Piaggio tells them to go whistle when they go Pop. Owners have two choices. Pay to have it done or part the bike out. Most opt to rollerise. It isn't that expensive and I bring bits in from Europe at a substantial saving over buying locally.

So that is the reason why I will always offer an alternative explanation when people, anyone, argues that their bike is fine and others don't have to worry. I know better based on hard learned experience. I defended the flat tappet motor for far too long because I too wasn't looking in the right place. As soon as I did it became clear that I was wrong. My defence of the design sits very uneasily with me and I don't want other people making the same mistake I did.

Typically up front of you Mick.
Actually it pulls like two trains joined together, I do remember the sound as you strolled past the line of cars but it got quiet again as you disappeared.

Hi Griso 8V.
If you intend to save yourself the trouble of taking your bike to the local crusher to destroy it and ride it to death instead, that is your perogative and yours alone, but by suggesting that you are "living dangerously" you are implying that there is some chance, however small, that you may dodge a bullet that is coming at you at extreme speed and will avoid the consequences that have befallen (or will befall), every other 8V owner that likes the taste of sand.
Will you let us know how your bike is at each 10,000 k interval ?
I remember the old "blow up nights" at Mt Panorama every Easter in the good old days. Watching a CB 350 Honda weld itself together at night with glowing headers @ peak revs with the oil drained out, was always a huge chortle..
Imagine the unbridalled mirth associated with the wanton destruction of a nice Griso donk when the easy solution was at hand..
Utterly priceless..!
BTW..
I reckon you might be taking the piss..
If so, you had me going for at least a minute... :clock:

When you decide to look at those tappets you'll find something like this:
(https://photos.smugmug.com/Motorcycles/12-Stelvio-NTX/i-LtFW4qh/0/162622fd/M/4flats-M.jpg)
  My Stelvio had about your mileage and had been maintained by the book...my dealer told me that all was OK (I do not think he even looked at the tappets).  At least the damage will be done slowly at first and you will probably hear the thrashing sounds before it locks up.  Nevertheless, by then the motive lump will be junk as a result of all that swarf swimming through the oil system.

Sure. That's what prerogative means, especially a right not held by everyone. Look it up. This was intended as a play on the word, like your reference to the meaning of "vise."

Also maybe we should discuss the use of single and/or double quotation marks, I'm a bit hazy on that as well.

The single quotes before double is British usage, but I was doing it to try to avoid having my quotes displayed as little black triangles. A better bet is to turn off smart quotes for my system.

Pay a little now or junk it later, These were from a 10K mi 8V, I changed them every 10K mi then rollers the 3rd time.
Keep your ears open, it will make a rhythmic tapping noise.
Trade it in w/you hear it for a Black or Red Devil, cause it's not covered under warranty anymore. Then your dealer can fix it on their dime if they are still around.

Is this so? I was talking to a mate who is still a dealer here a few weeks ago and he said that while it was well nigh impossible to get any information or help about anything from the new importer he hadn't been specifically told that the factory was abandoning all support for flat tappet models. It wouldn't surprise me as unfortunately nothing about Piaggio management surprises me any more but you'd think that on something so fundamental they would put something up on the Servicemotoguzzi site at least?

Certainly there are still lots of bikes getting rollerised. The supplier I use in Europe lists the available numbers of parts on their website and they're churning through conversion kits at a fair old rate so there must be a lot of folks out there doing it on their own dime! I can't imagine if one of the major suppliers is doing loads of kits the other ones won't be.

Your bike and your wallet are *definitely* circling the drain. Once you discover the engine damage by noise, it is not far off from hearing the *click* from stepping on a landmine.

You visited several forums and posted here with some sort of agenda, and have now received 100% pure gold advice from one of this planet's most gifted Moto Guzzi mechanics, who, apart from that little noodle, also shares his knowledge freely despite likely not having any time.

 :huh: I get where Griso 8V is coming from, there are all kinds of wacko internet forum issues. Right now on the Tundra Forum, people are yacking about 'cam tower leaking'...........

When I first entered the MG world, I had the same attitude towards flat tappets.... i.e.  "good maintenance, care, riding, and oil changes will prevent this possible issue"  Having had the benifit of hanging out with and talking with Street & Steak (Ghetto dwellers) and Jason at MI as well as several conversations with Dave, and reading in the forums, I realized it was a 'when' not 'if' proposition, and shifted my 8V search to a factory rollerized bike, as plan to keep the bike until my own chassis and lifters take a powder.....

Griso 8V, there's no telling where your motor is in its self destruction, and you may like to live dangerously, but be prepared, you may have already spooged your motor, and need not only the roller kit, but a tear down and cleaning of the sump and journals. You will have to do it, and I am with Pete, I hope you dont change the oil, tighten down the adjusters to hide the sound and sell to an unsuspecting buyer smitten with the Griso. Not sure how many unrollerized early 8V's are out there but 3 years ago, there were tons of them.

There's an old verse in the Bible that applies here I think.....  If I say to the wicked, ‘You shall surely die,’ and you give him no warning, nor speak to warn the wicked from his wicked way, in order to save his life, that wicked person shall die for his iniquity, but his blood I will require at your hand. But if you warn the wicked, and he does not turn from his wickedness, or from his wicked way, he shall die for his iniquity, but you will have delivered your soul.

I do have to say, my 8V, and those I've heard are so loud, I cant imagine what a sick flat tappet motor sounds like........

I thought I smelled something piscatorial early on..
I think we're victims of a fishing expedition, or we're all in for a good laugh, or some poor bastard is gunna' get a nice Griso sometime in the future with a brand new service done and the valve lash freshly adjusted...
I just hope the potential new owner is a WG member (or guest...)
Our OP says that he wouldn't pass on a dying bike to an unsuspecting buyer.
The question is..
What will happen if the Griso comes up for sale.
Will our fortune teller take the covers off and if the tappets are rooted, say to the wide eyed would be victim..
"Sorry mate, I really can't in all conscience sell it to you, it's shagged..."
Or keep it and ride it 'till it dies...

With regular clearance checks I probably would have made it another 7k to where you are now.  Some have made it much longer, but it doesn't change the fact that DLC, harder than any other part of the motor, is swimming inside of there.  And plenty of others have discovered that once all the DLC is off the bottom of the tappets bad things start to happen.

Here's mine at 8k.

(http://i235.photobucket.com/albums/ee208/worwig/publicshare/20160206_140317.jpg)


Otherwise, I would agree with you that the 8V motor, with the proper rollers, needs little attention.

3. He really thinks he may have the one pre-roller 8v that will not fall.

Also, do not approach an adult Emu tending it's young whilst astride a motorcycle. Said adult Emu will run directly at motorcycle, in some sort of defensive attack mode, causing rider of motorcycle to release a little bit of wee.

Unfortunately the OP appears to be on a vacation to Egypt floating down the Denial. I had my Norge done at a bit over 12K miles and the left side was just starting to show wear. For whatever reason I did not get any financial help from Moto Guzzi when a claim was made and had to pay full boat but I have piece of mind. Otherwise the 8V motor seems to be a very good one.

Another useless fact about Emus is that the males do all of the rearing of the chicks after hatching. From memory the hen hangs around until the eggs hatch and then buggers off to play Bingo or some such leaving muggins to do all the child rearing.

No good stealing mine.
They were disconnected from the mains supply years ago. True to say though, there may not be any additives in the water, but there's plenty in the tap..!

reminds of snorkeling in Grand Cayman when a brown ugly Moray Eel did that to me.   I turned and tried to run (not swim) away.  Luckily made it alive.  Got back in the tour boat and everyone was laughing at me.  They told me a couple of 12 year old kids were poking at the eel just before I got there.

Just a note about the mileage at point of failure -  GuzziSteve can correct me if I'm wrong because I'm working from memory here but he did the work on my 2011 flattie Stelvio. He's done ALL the work on that bike since he did the PDI on it at the dealer. He found out about the issue with the tappets and told me right around the 12k mile service.

My viewpoint was "if it needs fixing- fix it!"
He checked for wear at 12k miles and found none. I remember him saying the factory didn't want to pay for a kit to rollerise unless wear was found.
Steve checked for wear again at the 18k service and again found none but said he was surprised and wanted to keep a closer eye on it.
He checked again at 20,800 miles and found the beginning of wear - just enough to get the factory to give the go ahead for the parts.

So, at just under 21k he rollerised my Stelvio and it has gone just about 12k trouble-free miles since.

I'm certainly not contradicting Pete or GuzziSteve - you guys work on them and I just ride them - but is it possible the OP's bike just hasn't shown wear yet?

Post by: lucian on January 03, 2019, 05:18:23 PM
but is it possible the OP's bike just hasn't shown wear yet?

At 15,000 miles I would say it's possible but  unlikely.  Especially when he mentions many short trips and damp conditions.  Why he would think of  putting off     
rollerizing his bike  is beyond any measure of common sense .

Looks like you caught those just in time .  Obviously DLC  missing, but not yet chewing into the base metal.  Easy to see the heat rash on the cam noses.
 Has there ever been a definitive answer as to the cause of the failed design?  The followers all seem to show rotation , and  they seem to get enough oil.
 I know someone was talking about excessive valve spring pressures which might explain why all three materials tried in the followers failed.

Title: Re: Griso 8V 15K Miles
Post by: guzzisteve on January 03, 2019, 07:25:25 PM
I changed the 1st 8V's here and they had square spots. 1st Factory Bulletin was done at our shop in ATL.
Reason for failure was the coating process was inconsistent for most, spring pressure maybe but most kits don't get springs for rollers.
I really don't care why, my job is to fix it not ask why. Guzzi's engineering screwed up, that's why!!

Pete was into this early on w/pics from under the microscope, showed the DLC coating cracked & separating. I'm not into the why part. Just fixin it.
Title: Re: Griso 8V 15K Miles
Post by: pete roper on January 03, 2019, 09:29:12 PM
I'm pretty sure I know the reason, I've explained it before. Whether I'm right or wrong is of no consequence but I can say with absolute certainty that using the 'Factory' recommended oil will make zero difference and it's not any of the usual 'Catch-All' answers that are usually offered.

I don't own an 8 V, but I get the message that rollerising a motor that has done 30,000 or more, is not the whole solution.
To do the job right, you'd need to tear down the donk and wash/check the internal condition.
With all the shit and corruption floating around inside, aren't you just risking the buggering up of your new components in the roller rockers ?
Title: Re: Griso 8V 15K Miles
Post by: pete roper on January 04, 2019, 01:08:37 PM
Remember that is just getting the cambox off. If the bike is pre middle of 2010 the heads have to come off as well for shim fitment and the rockers have to be swapped into the new camboxes.

Dropping the sump to give it a good clean I also consider vital. The factory's suggestion of simply 'Flushing' with a couple of litres of oil is a joke!
