GRiSO Tenni

Hi all, Bob from Holland here.

First GRiSO I saw was 10 years ago at a motor show, pearly blue 1100, intrigued but couldn't afford it then. Last August I bumped into a GRiSO 1200 8v Tenni and just had to go for it!

See picture 1 (2?)

It came with an Arrows exhaust,  nice big sound but coming off a Honda VF1000F2 it was a bit much for me. Also, I like original, so I found an original 8v exhaust which I have on it now.

See picture 2 (1?)

The exhaust came with a part that I don't know what to do with (and haven't fitted): a ring with a mesh, it fits size-wise in the pipe but it seems to me there's nothing to keep it "stuck" or in place somewhere. Can anybody tell me what it is (db-killer?) and where to fit it?

See picture 3

It's the catalytic converter. A press fit at the front usually. What year is your Tenni and is it rollerised if pre-mid 2012?

It was first admitted to the road August 2010 (don't know where, Italy probably), imported in The Netherlands May 2014, and has since had the updates at the Dutch dealership.

Sorry, that means nothing. A 2010 would, maybe, of had the upgrade from cast iron to steel tappets.

There was never a recall for rollerisation. Lift a rocker cover and check. If you still have flat tappets don't ride again until it has been rollerised.

Another one who favours the stock muffler

I did the same with my Tenni, went from GPR back to stock.
Looks somewhat bulky from the side (?), but seen from behind, nothing, NOTHING beats it!
And the sound is as it should be, deep, rumbling and discreet

Anyway, that's my opinion...

Most dealers are in complete denial about rollerisation, they would be as they are selling potential used time bombs

I bought mine at TLM (Nijmegen, Netherlands). I asked when I bought it, and just had it confirmed today, that is has been "rollerised" - so no worries

(And I was assured that this is the case for every 8V Moto Guzzi they sell.)

Hm, what is next to it in pic 1?

Next to it is a V85TT (2022) in almost matching green, en in front 2x Honda VF1000 F2. For the last 12 years (since I have my license) I only had VF1000 F2s - great bike, but in the end wanted something new. This summer I first bought the V85TT (really was the only new model bike that I really like), then found the GRiSO - and just recently (because someone said "you can't keep them all!") got rid of the Hondas (and a load of spares...)

Indeed, when I was looking at a non updated 8V and questioned the dealer about doing the upgrade proactively I was told

"Well, they don`t all fail so you just wait and retrofit if and when it does"

I expressed concern of damage to other components following this method.

Answer was "That`s what oil filters are for"

 Didn`t inspire confidence so I bought a 4V

You pay for it, not them. That's what it's about. They still get cams for free & don't want to spend their time to make it right. Unpaid labor to make a sale. It'll sit a long time.

Fucking brilliant! So all the crap that goes through the oil pump before it gets to the filter doesn't matter? And the cooling circuit is unfiltered. And what happens if the filter goes into bypass?

Where do these morons come from???

A good use for the overused joke ‘How can you tell if a salesperson is lying? Their mouth is moving!’
Earlier in the year a 2010 GRiSO followed me home. Verified with valve cover removal the bike I was looking at had not been upgraded. It had traveled just under 5,000 miles with maintenance by one of the best, and had been immaculately cared for so I took a chance, and offered 50% of the ask.
Took it home in my trailer and immediately took the left head off. One pinhead sized piece of dlc gone from the center of a tappet and the beginning of a hot spot on the camshaft lobe high point. To me, this verified Pete’s opinion that they ALL need rollerization to be correct.
Piaggio’s handling of the entire issue has been a disgrace to the Guzzi brand, but far from unprecedented.
Hop over to accessnorton.com to see how the new owners of Norton are treating those who bought one of the famously beautiful, and troubled 961 Commandos from the Stuart Garner era of ownership.
Amazing to me there are enough fanatics to keep companies - that treat their customers this way - alive.

Those Tenni's are irresistible! Congratulations and welcome to the Ghetto!

Welcome to the Ghetto, Bob!

Hey, thanks!

Nice!!

Beautiful
