After reading the breather disaster n roller cam issue I realise that incompetence isn’t just a U.K. thing. The amount of clowns who purport to be technicians must be a worldwide phenomenon. Think we in the U.K. have developed this to an art form.
       My question have a black devil GRiSO hardly used I assumed being a late model that it’s rollerized am I right in this assumption ?
 
         Real sorry to hear the breather story best of luck

            Regards Roger U.K.

I think that after a certain production year they were factory roller.

Easy to check tho

If you are willing to trust Motor Guzzi, the crossover from Flat to Roller. This is by motor number and not serial number:

Stelvio- Motor#AC12596 Build Date 12 March 2012
GRiSO - Motor#A813524 Build Date 12 April 2012
Norge - Motor#AA12214 Build Date 18 April 2012

Me I would pop the cover and take a look

Well thanks guys have a look at the number tomorrow n pop the cover if in doubt. Has anyone collated the information, known issues/ solutions . The dealers here seem to change as they refuse to take the expected sales for the Californian which flopped so experience has often been lost , new dealers are supermarkets enthusiasts like me need to be self reliant . What a great help this forum is 👍

It's been covered here many times. Guzzi's figures are rubbery. Anything before a MY 13 machine it is worth checking. From 2013 on you can be pretty certain it's a roller.

If you are going to check make sure you take the plug caps off without damaging them by flicking them off the plugs from underneath rather than pulling them from the top.

Unless it's an 8V Sport - all of them had flatties till the end of production - the A7 motor.

Yup, but his bike in question is a GRiSO Tony. Salient point though.

Were it me, I'd still pop a rocker cover to confirm. If not now, certainly during my next valve adjustment.
