Brian, From pic you show of the Imola Head, his looks like a Lario head (yours on the left).-Kevin
After blowing your pic up I can now see the chamber through the blackness. I thought it was round. It is not. Kevin
I wonder the same thing. Why didn't they downsize the setup from the current big block 8v? Only Piaggio knows...
I highly suspect it is all about marketing. If you look what they are doing with the small blocks you can see a plan in action. First Aprilia does a work over of the SB to bring it up to a more modern function with the Breva 750 and Nevada. A few years later, Piaggio does another, pushing it a bit farther with the latest v7 series and Nevada. Sales have been increasing all along, once the first gen v7 series came out it became guzzi biggest selling line. With the second gen v7 series sales have surged forward even more. It seems clear to me Piaggio will run this current line as long as it can, and at some point when sales numbers begin to level off or decline the 3rd gen v7 series will come out, with a 4v head.
Why? What's wrong with the RACER GT or some such?
Where do you go from "Racer"? ::)Kevin

Yes they look VERY similar, but they are not - the Imola head are different on the points I have listed above the pic. Just bring out the "yard stick" and you'll see ;DYou can see the valves are smaller too on the Imola head, the shop manual will tell you too :)
Just give me a heads-up. The V7R isn't getting enough riding.

Thanks for the input on that Brian! When the Lario head gets here I will be able to do a side by side comparison and see about the combustion chamber dimensions. I have spoken with Millenium Technologies about the head work, if I need to change the combustion chamber, they can do it for me. http://www.mt-llc.com/head.phpOn the issue of the valves being different lengths, I have a stock Lario valve that I measured for length, and it was the same as the Imola II valve. I will take a picture of them next to a scale ruler tomorrow night and post it. Brian, you say the parts book lists the Imola valve as shorter? I don't have a Imola II parts book. Can not find one. Still gathering information! ;-TCheers!
Well - having a spare Lario head isn't bad at all - just in case ;)I have a couple myself, and hope never to use them as replacements on my Lario's, but as parts to rebuild additional mills one may come accross and take pitty on ;DMy suggested valve spring solution, as so many other solutions, although similar in natur, are still very much based on faith. Not many or non has piled the number of km/miles on one to be conclusive about the solution, but that's part of the fun and excitement right :o ::) ;) ;DThere are no two ways about replacing the cam shaft if the existing one has 12mm lobes, Guzzi did that to all the 8V's some time in 1986 - engine numbers available in Guzziology, but the springs in relation to the Lario, is solely based on what Guzzi did to the 2V/head SB's documented in the 750cc SB shop addendum. They never suggested it to the 4V/heads. My assumptiom is they just wanted to forget about them at the time they did this to the 2V/head SB's, and one has to bear in mind, that these springs being softer, will allow "valve float" on, or just after the red line.
I would go positively nuts, if Guzzi would revamp the 8V SB and apply a solution like this on a new revamped Lario release. It should not be this complicated to the Piaggio engine nerds. I'd keep it air cooled though ;D
Why are the intakes connected to each of the cylinders and not tb's?-K
Late model bevel - awesome.Much more costly and labour intensive to manufacture, potentially fragile - but elegant and beautiful!
