    I finally got sick of my suspension assaulting my spine so on the weekend i paid someone to set it all up for me, and the change is :woohoo: .
    The settings were done based on 110kg.

    All settings are from fully wound in, hardest settings.
    Front.
    Sag 33mm
    Comp 2 turns
    Rebound 3/4 turn
    Tyre Pressure 33lb

    Rear
    Sag 32mm
    Comp 3 Turns
    Rebound 15 clicks. When 2 up, 11 clicks
    Tyre Pressure 36lb

    This guy is an ex racer who now runs Q-ride diding school. He really explained in simple terms how it all works and how much the tyres play a part in the whole process. By looking at my back tyre he was able to tell how i rode, which is hard into a corner, backing off a little and then hard out. So i am tearing up the edges. And he was right :blush: .

    I have always run my pressures at 38-40 psi so when i went for a test after he made some adjustments and i could really feel the pressures were to high. He then set the pressures as above once the tyres had cooled off and i went for another test. When i got back he checked them again and the pressures had gone back up to where they had been.

    So it turns out i have basically been cooking the tyres, therefore reducing the life and the handling capabilities.
    I also had mismatched tyres, a 55 profile front and a 60 rear at 170 wide. This means that when the rear is at it's edge the front still has some way to go. I am changing the rear to a 180/55.

    So on the 80klm ride home i was able to make some findings.
    1. No more spine assaulting. Nice and smooth with plenty of feel.
    2. Heavier steering, but very stable through the corners.
    3. No more scary diving when front braking.
    4. The whole package is easier to ride which means i can probably ride quicker.

    So, if you're about my weight give these settings a go, i'm sure they will work for you.
    Now i can't wait to get my new tyre and go for a blast.

    Yes, inquiring minds ... and large bodies :lol: ... want to know.

    Bought a maintenance stand for the Griso, and am itching to spend this long winter fiddling with suspension, etc.

    Yes, I know, leave well enough alone. If I still lived in Georgia, I would and just ride, but time hangs heavily here on these short days. I spend so much time down in the apartment's garage putzing with the Norge and Griso that I worry someone's going to call the police about "that strange man." :laugh:

    The comp damping was WAY too far turned in on my bike. It made it hammer you at any expansion joint, bump, etc. Turning those out quite a bit and playing with the rebound helped quite a bit.

    I also dropped the forks in the clamps to the lowest line and it helped kill the corner wallow.

    Look into the manual and start with MG's 'race' settings and go from there.

    I'm amazed how fat my Guzzi is. Everytime I jump on my 1200 Bandit it feels like jumping on a bicycle.

    I have a funny picture somewhere with a friend of mine (the guy's huge) on my bike...
    I'll see if I can find it for you.
    It illustrates perfectly what I was saying. :D

    Just wanted to say thanks to Double D for sharing his suspension settings for Fat Geeza's! I used these shock settings with the exception of using 14 clicks for the rear rebound since I'm about 30 lbs. heavier (a Fatter Geeza) and that was the only shock setting change that was noted as changing for 2-up (i.e. higher weight). I also used the tire pressures as recommended above. The bike handled great and I was saved the spine jolts over the bumps.

    Next step will be adjusting the preload once I get the proper wrenches.

    Dave

    Too funny doubled :happy:

    As the new owner of your old bike, I too, weigh in around the 110kg mark.
    The owners manual has all this stuff marked, is that right way round or upside down?
    :h: the bike, every ride is better as I accustom myself to its seductions and delights.
    Better than a mistress :D

    UPDATE 23/9/14, 2.50pm Aussie time : a 200k ride today in beautiful weather.
    Suspension is great, perhaps a little soft at the rear (like me), which I liken to a warning when it bottoms out. The ride is nearly plush, for a Guzzi.

    Map from Todd works a treat, a huge improvement on the old one.
    The smoothness and lack of bad manners is exceptional, maybe a tad thirsty at 5.6l/100ks.
    What a pleasure to ride.

    I'd like an Agostini
    oform, now it's only about finding the money.
    The Staintune (quiet as a mouse) will have to stay for now.

    Was this suspension nirvana achieved utilising the stock rear spring? My preload on my 2015 Griso is cranked all of the way down and it's still not enough. I found that the stock spring is for a 140lb rider. I'm 220 with my gear on! Any suggestions on spring changes?

    I should have the stock spring specs on the site, try a search. But, based on my experience with the stock suspension, don't waste your time and money.

    Ha! I test ride a Monster 750. Was giggling at how tiny it felt. My Griso felt like a massive barge after that spirited wheelie producing hop.

    As a side note and I can't remember, is "fully in" all the way counter clockwise to a hard stop?

    I'd be thrilled to get fuel consumption for my 2014 Griso into the mid 5s. Mid to high 6s is my average, and I'm not a hard rider either. Mine is stock aside from Termi pipe (db killer in).

    Thanks for posting these settings. I am 95kg but carrying touring luggage so used these settings and the bike rides lovely.

    Thanks again.
