OK, 2V engine 16 bolts to remove rocker covers and four adjusters to adjust. Total of 36 *Operations* to perform to adjust valves. 8V? 8 bolts to remove rocker covers and eight adjusters to adjust. Total number of *Operations* to perform valve adjust? 24! Now, which one was quicker and easier again? ??

You've forgotten Murphy's law

With the 4v I only have 6 things to screw up valves and valve cover gaskets

With the 8v I have 10 things to screw up  and believe me Murphy seems to be my neighbor

For me thenumber of things that can be screwed up define how quick and easy it is.  this comes from decades of personal experience     :pop

 Suppose you were an experienced rider but never on a Guzzi...Would you be able to tell the difference between a 2 and 4 valve head after a ride?

That's a tough one. I'd say probably not. What would you base your observations against? <shrug>

My Vintage is the only Guzzi I've owned, so I'm not really qualified to compare. However, I don't care for the complexity of the electronic gizmos (though I've grown rather fond of electronic FI and ignition) and I've never craved more power than the 2V delivers. I lusted for a Big Block for a long time before I finally pulled the trigger on mine back in '07. If it keeps delivering big smiles, I may never know what I'm missing...

I can answer this.  Before I purchased my first Guzzi a used 02 V11, I never rode a Guzzi before.
I test rode new Guzzi's at MI before the used purchase.
Rode the 2V and 4V Griso as well as the 1st Gen Stelvio, all back to back.
I could clearly feel the difference in the 2V and 4v motors in the Griso.
The performance differences were exactly what I expected and what everyone here knows.

The better question in my mind is if you could not see the engines, would you think/suspect they are related?  If I was the pop of these 2 pups I'd definitely be asking mom why one of my boys was born speaking fluent swahili.
