Oh man!  Explain those pics.  Bronze I take it?  What kind of compression you looking at getting?  what kind of valve size?  We might get ours done about the same time.  Both will be VERY interesting.  Both seems expensive!  :o  Hey... if Guzzi aint gonna do it somebody has to.  ;-T
Keep us posted.

This is really exciting  ;-T

Totally uncharted territory. Seems like Millenium has their ducks in a real nice row working these heads out.
You and Kevin are pioneers, and paving a nice road others may travel fully or partly when you are done  ;-T
You have gone way beyond stock on your mills doing stuff the next guy has only thought about.

Hey Brian, nothing new to report :(.  In order to get the CHT probe hole placed in the head, I have to remove the existing right hand head from my bike and ship it to Millenium so that they can match it.  Of course that means my bike will be unrideable until the work is done.  I am waiting until summer is over before I do that, the weather is just too nice to have my bike taken apart!  I will probably do it in September, and finish up the project then.  As a side note, I had bronze guides and seats installed for better heat transfer.  The Imola heads are .090 inches thicker than the Lario heads, so I need to have that dimension removed to keep the same compression ratio, and the valvetrain geometry correct.  Hope you are having a good summer.  Thanks for the Lario Facebook page by the way!  I have used a lot of the information from there to help with my project!
Cheers.

You are so welcome Mike. Happy to be of service.

I wouldn't take apart my bike in the middle of season either if I could avoid it. You are executing a unique project, and I assume a lot of Guzzita will be following the results.

We have nice weather here too - finally - so my Lario is constantly on the road. The rest of the herd is a bit neglected  ;D

Ride safely.

Cheers

Yes Mike, any updates to the project?  I can offer up that my experience with the hopped up Lario has been fantastic after getting the fueling together.  Pretty incredible what can be had with a little upgrading from stock.  Much patience is understood from your audience, but any updates appreciated.

I am finally back in business, able to work on this project.  I have all the parts I need....I think.
I removed the two valve heads this evening, planning on swapping out the cam tomorrow night.
Hope to have the bike running by next week.
Apologies for my long absence!!

well, you can tell i live on a dirt road..got the Stator pulled off and hung out of the way. Used a 15/16ths socket and an impact wrench to pull the rotor.  was going to remove the timing cover and cam, but decided to work on the cylinders some...

Got this cylinder off...



Removed the cylinder studs, the top two studs are going to be relocated to the bottom two holes. the Volkswagen studs go in the top two holes.



Got the studs in this side...

Pulling the studs on the right side. Using the stud tool makes it pretty easy. 



Here is why I have to change the cam.  The Lario cam is on the right.  The left is a new V7 Classic cam that I got from Harpers.  The lobes are DLC coated. No way to make the Lario cam work with the later model ECU.



Stuff that I took off tonight...



And stuff to go back on....

Tomorrow evening the goal is to have the new cam and lifters installed, cam timed, chain and tensioner on, and timing cover on.  Have to see how it goes.

<scratching head> How are you going to keep the lifters from falling down into the case when you pull the cam? I turned the engine upside down. Fortunately, I didn't have to learn how that babbitt (I think) thrust thingy (technical term) goes on the new cam..

I'm using Guzzi V75 pistons that I got from eBay Italy.  Go back a couple of pages in this thread..there are pictures of them.  I had to have custom wrist pins made and get the pistons lightened for weight.  Trying to keep the balance the same.  The replacement pistons are within 1/10 of a gram of the stock ones now.

I can reach the lifters from inside the cylinder base hole....figured I would just hold them up as I pull the cam out...suppose I could clamp them up somehow, not sure I will need to.  I do not want to use anything magnetic on them.  We will find out tonight!

One thing you might want to take note of: it looks like your alternator rotor is a permanent magnet type.  If it is, you should store the rotor inside the stator.  The rotor needs to be close to the "keeper" for reasons having to do with magnetic flux lines, domain walls, and entropy.  Short version is storing the rotor bare for days on end can weaken the permanent magnets, which will reduce the alternator output.  Other than that, keep up the good work, and keep the pictures coming!
