Hi all. I sent in the queries below in July and received some advice
and insight into working on my '73 Eldorado. I have since rewired the
entire bike with a loom from Gordon at MG Cycles. The bike started
immediately without choking and ran fine but would only rev up to
about 3000 RPM. I had disassembled cleaned and reassembled the carbs
and set the timing with a timing light according to the manual. Still
no luck with the 3000 RPM rev limit. I decided to look into the carbs,
specifically the accelerator pumps and discovered the spring on top of
the plungers! Aha! Put the springs under the plunger and restarted the
bike. Same outcome. No revs above 3K. Let the bike sit for a week. Took
out the pumps and held them up right in a bowl of water as they would
sit in the float bowls and used a needle valve to depress the spring
and then "opened" the throttle, so to speak. No fuel. Put the plunger
in upside down from what I originally assembled, retest, Voila! Fuel,
or rather water spurted through the jet oriface. Dried them, put them
back in the carbs. Started the bike and had a
short, fast high RPM test ride. All electrics work great now, except
the turn signals still waiting to be mounted. Engine is strong, lots of
torque, no smoking, very little blowby and no odd engine noises.
Looking forward to my shakedown ride this weekend.

Thanks, again, to Greg Bender, Gordon, Mark E. and all the others
offering support and advice. I now have a great running Eldorado, a
slumbering Ambassador, a very nice 850T3 in boxes, and a basket case,
genuine police Ambassador without a tank, side covers or windshield and
no compression on #2. At least I have one to ride into the winter and
maybe through it, since I am in Northern California.

Ciao,

Ken

Greetings to all,

I have recently acquired two Moto Guzzis, a 1971 Ambassador still
slumbering and a pretty nice
1973 Eldorado with quasi police setup; floorboards, LAPD side stand, a
trunk box. I have lusted after the
MG Vtwins since my Air Force days, but didn't scratch that itch until
about a month ago.

I am having midrange acceleration issues with the Eldorado that I
can't seem to conquer. I have timed it, at idle and at speed
according to the manual, removed, inspected, cleaned, remounted the
VHB30s and balanced them at idle. The previous owner had
reinstalled the accelerator pump pistons incorrectly and after I
corrected that, the bike ran much better. The bike starts right up
when cold, most of the time- about 80 degree F where I am- and runs
well through the gears as long as I don't try to blip the
throttle or accelerate past 3200 to 3500 RPM. If the throttles are
opened too much or pushed beyond the 3500
RPM "limit" the engine gasps bogs down, obviously either fuel starved
or, perhaps, unable to advance the
distributor far enough to provide spark. It seems like fuel
starvation, but I am, obviously, not sure. An MG mechanic
friend says there may be an issue with fuel tank venting, so I'll
check that, as well. Any advice would be welcomed.

Issue # 2 is electrical. Seems the coil/distributor circuit loses
juice or has a voltage loss at times. Could this
be due to the relay going to ground? The charging system works , as
the starter always cranks fine and seems
to have plenty of current for the start circuit, but, on testing, at
times, there will be no current to the distributor.
I will be rewiring the bike with an MG Cycle loom in the near future,
unless someone has a better suggestion
other than building my own loom. Comments on this issue are welcome as
well.

Thanks to everyone in advance. I have enjoyed the posts I've been
receiving and hope to contribute someday.

Hi Charles,

It is very simple to drill the look-alike choke lever. Just measure
carefully and then drill away. Alternatively, since it does not come
with a pin, you may be able to tighten it down sufficiently to not
need
a pin (but I think it will probably always want to move on you). On my
Ambo, I drilled the hole and then fabricated a little washer/pin
mechanism that works quite well. If I had to do it over, though, I'd
simply JB Weld in a short length of steel rod to act as a pin.

A fuse box is critical if you want to avoid melting all sorts of
wiring,
etc. If you don't have fuses, and get a short, wires will melt and
catch
fire and throw sparks and do all sorts of nasty stuff. Even if you
don't
have the stock fuse box, you need to run the current through fuses. If
you don't believe me, get a 12 volt battery, and connect the positive
and negative terminals directly with 12 gauge wire. That accidentally
happened to me the other day when I was testing a light bulb...lot's
of
excitement for a few seconds as I scrambled to unconnect my now-welded
leads and melted wires. :> I've been working with the Waytek company
to
find a replacement fuse box that will fit in the headlight shell. I'm
still putting together the order, but will let everyone know if it
works
out. I think an old Volkswagen Beetle fuse box MAY fit in the
headlight
shell. At least, that's what I've heard. I've never tried it, though.

As for a handlebar switch, I really like this one:
http://www.mgcycle.com/HANDLEBARSWITCHES.HTML
120030 KS left side switch - headlight on/off/park/hi/low, horn,
flash,
push to cancel turn signals - $58.95

It is nowhere close to being stock, but is infinitely easier to use
and
available at a very reasonable price. If you really want the pillbox
switches, call Mark Etheridge or keep a close eye on ebay for some
crusty ones you might be able to rebuild. Regardless of which switch
you
choose, I recommend using individual relays for the high and low beam
circuits (wiring diagrams for this are available in Guzziology and my
website).

Oooopps Sorry did press something by accident on my PC and did not
mean

to split my message... Here are the rest of questions:

1) How difficult is it to install (drill) the look alike choke lever
that MG cycle sells ???

2) My Ambo came with some weird wiring, eventually I will have to
redo
it... How important is it to have a fuse box, because I think the
one
on my Ambo has been removed from the headlight shell... Maybe I am
looking in the wrong place, please let me know

3) I need some recommandation on what (& where to buy) I can use for
handlebar switches controls for my headlight and horn ??? My head +
Taillight are wired thru the key switch ignition...

Thanks again to all for your super helpful answers...

Cheers

Charles
