Author Topic: Griso 8v clutch slip (Read 8168 times)

So the Griso has 34k miles on the clock - almost all hard urban riding, so the clutch has had plenty of use. It's started to slip quite badly. Pulling away I can gas it, and drop the clutch, and it just pulls away like an auto clutch! And in higher gears if I open it up, the revs rise but there's no drive.

I've flushed the clutch out with aerosol brake cleaner, with the plate disengaged, and turning it over with a screwdriver through the timing hole, and it doesn't seem to make that much difference.

Is there anything else I should be doing before I go right in there?

Make sure the clutch master cylinder grub screw has some free play. If you see any oil at the bottom of the bellhousing, the rear flange could have come loose due to lower bolts being too long. Lets hope it's the first issue!

I already had a crank seal failure at around 20k miles. Clutch was worn at that point, as you'd expect, but looked like it had plenty of life left. And there didn't appear to be any oil contamination, despite the leak which left a daily small puddle.

If you go in there and have the money I would put the Cali 14 system in it. It is beefier & a bit better. The newer Stelvio's have this clutch. An update if you plan on keeping the bike. Cost is just under $600 for the kit. You have to check the pushrod length at same time so it all works right.

Looks like I need to book a weekend with my tame Guzzi spanner man. And re-mortgage...

Have him do the rollers too!

Roller cam followers? Done two years ago. This bike failed before the original recall, and has had 5 sets of cams and followers! (All on extended warranty)

Any of the failed ones rollers?

I was riding my Bandit in The City one day. Every time I left a stop light it was revving and slipping. It only took 10 or so times to figure out it was my rear tire slipping on dusty pavement (not pun intended, Randy

)

My Griso needed replacing before 30k miles but I think it was from a lot of spirited canyon riding.

not by me

No. Had rollers fitted, finally, about two years ago. It's been fine since.

That is good to know bout the rollers.

Yep. So far.. no roller issues that I know of. That would be a very good thing.

Really, have the roller conversions/update kits been around that long?

The first Tech Bulletin on "A" kit was 2013. This is why it is important for the dealer to actually read the stuff and act on it. Also to communicate this to the customers.
It is called DOING YOUR JOB. Most do not do this cause you can't bill the time to anyone.

Are the tech bulletins for the CARC bikes online somewhere?

And while I'm here, I keep hearing about the "riding season". What do you guys do when its not the riding season? I mean, do you just hibernate? What if you want to go somewhere?

In the middle of the summer when the temperature gets over 100F, and the humidity is way up, I may opt for an air conditioned vehicle. That must be what they mean.

Not riding season is when you do projects. I'd never get anything done if it was "riding season" all the time.

They are on servicemotoguzzi site for dealers. To let us know about problems and cures. It's up to the dealer to tell you. Most don't.

Well we stripped it yesterday.

Interesting process. We put the bike on the bench and hung the frame with ratchet straps to the roof joists. Then we removed the rear wheel,bevel box and shaft, and sat the engine on a jack. Disconnected everything, lowered the bench and then jacked the engine down out of the bike, leaving the frame hanging from the roof. Worked a treat.

In the process we discovered:

- the clutch was totally worn out - down to the rivets!
- the swinging arm taper rollers were a thing of the past- hadn't even noticed.
- the crank oil seal was leaking
-as was the gasket in the bearing holder plate (whatever that is called).

New clutch now installed, new bearing seats and taper rollers, and new crank oil seal.

The engine is back in the frame, but still needs some work to reconnect everything, and replace the drive and rear wheel.

Nearly there.

You must have torn up those London streets pretty good judging by that amount of failures.

Who did the roller cam conversion?

I'm guessing you already know about the 2 lower rear flange bolts being too long? That's what causes the rear seal failure. Hoping you haven't put it back together yet?

I am an...enthusiastic.. ..urban warrior. Trained on a LeMans III and two Speed Triples.

Corsa Italiana did the conversion.

I do know it better now. But I can't take the credit - the technical know-how came from my Guzzi man!
