sounds like you MAY have found the problem. i'd bang it back together & fire
it up. if that wasn't the problem, i doubt you'd cause too much more damage.

i wouldn't worry about the gouges on the crank. i assume the threaded "cam
bolt" you mention is one of the 2 lower studs that attach the engine to the
trans. these come out from the gearbox side. don't try bunging them up in
the sump.

good luck

 Drained the oil and dropped the pan, low and behold I found presents.
Way back 2+ years ago when the Guzzi dealer had the bike, he told me it
didn't have a dipstick, just an oil fill hole plug/bolt, so I bought one
of those easy remove dipsticks from Harpers. I asked him if he dropped
the pan to clean things up and to make sure the stick wasn't inside,
"yes" was his answer. B.S.!! Lying in the pan was the original oil
level dipstick that must have been attached to the bolt he removed at
one time and it's been sitting in the pan for I don't know how long. I
searched throughout the case while on my back on the ground looking up
and must say everything looked pretty darn clean, even the oil screen.
The chrome on the inside of the cylinders looked good too, and as far as
I can tell, the connecting rods appeared unharmed. Everything was in
place, all nuts/bolts were connected. I manually turned over the motor
and didn't notice anything obviously wrong, but the bottom line is I am
no mechanic and I don't know what to look for. I did find some metal
filings in the front left corner of the pan and tried to investigate
where they could possibly be coming from. Only thing I could see is the
bottom of both ends of the crankshaft (those huge lobe things where the
connecting rods attach in between) seemed to have some small gouges in
them, one side a little more than the other. Perhaps the dipstick was
sitting straight up and was catching the crank end as it came swinging
back down and caused some of the crank metal to score off - maybe that
was the metallic sound I was hearing? I'm hoping the little bit of
metal that came off of the crank lobes won't be a problem, they are
pretty darn huge and heavy, can't imagine it would be a problem? Heck,
maybe this was also part of my starter hesitation/lock up? I don't
know, all guesses here. What do y'all think on this, could this oil
dipstick have caused the knocking/clacking noise or would it have just
sat there on the bottom of the oil pan harmless? Perhaps I should
button her all back up and fire her up and see.

Oh, BTW, I can see that hole in the rear of the case where the cam bolt
(?) goes through to the tranny, the one that is infamous to cause oil to
leak around the threads (if not coated) and leak out between the
engine/trans case. Is there anyway of plugging this up while I am there
or must it be done from the tranny side?

Eagerly awaiting feedback to see if my problem has been solved or if
it's worse than I thought.

Thanx All!

 Keith, I also agree with Kevin. I have had to rebuild my Eldo motor as
the cylinders were shot and when I dissassembled the motor, foudn the
sludge trap full and both Big End bearings on the marginal side. Luckily
both front and rear main journals and bearings checked out OK.
My engine was dissassembled for almost 10 years before I reassembled it.
It is fairly simple and I had an old Premiere service manual for the
V700 and 750, not the 850. I got a lot of advice from Larry Klein of GT
Motors in nearby Lansing, MI.

Good Luck. Take it nice and easy and LABEL EVERYTHING!!!
