Jeff,
The process is also described in the old Chilton's manuals, which
cover a number of different bikes from the era (might be available in your
local public library). The books call out special Guzzi tools, but I think
you might be able to do it using a degree wheel set up on the crankshaft and
a dial indicator set up on the rocker. You need the specs, i.e., intake open
@ XX deg before botttom dead center, closes XX deg ATDC. Those specs rely
upon a checking clearance (valve lash), and hopefully they are listed too. I
think I have the data somewhere-if you can't get it I'll look around for
them.
The cam gear is held on with a center bolt and a dowel pin. The gear has 5
different holes for the dowel pin, which is how you vernier in the cam. The
number of teeth on the cam gear (I seem to remember 72)does not divide
evenly by 5, so the drill is move the cam forward 1 dowel pin hole, then
rotate the cam back a number of teeth. with this method you can degree in
your cam within a degree or two.
If you have a feel for what I'm talking about, then this may be sufficient.
If not, contact me off-list. I went through this whole drill last fall with
my V7 Sport & I have some extensive notes written up on it that may shed
some more light on it. It's really not that tough once you understand the
process & you have the tools.
