Subject: Laverda reminders on posting to the lists
Hello people,
I've had a small spate of bounced submissions to the lists recently.
You need to remember that the lists are set up to reject submissions
from addresses that do not appear in the subscriber lists (this is to
reduce the chance of spam messages).
So if your sysop just changed your email address from
elmer.fudd@wb.com to e.fudd@wb.com, or you have different mail server
names inserted at random into the domain name, or if you are
subscribed at home but decided to send something in from work, it is
going to be bounced to me and not appear on the list.
One caveat - if you have two accounts with identical user names but
differing domain names it SHOULD recognize and allow the submission,
but I won't swear for sure it will work.
Please keep this in mind, along with not using the words h*lp,
subscr*be, unsubscr*be in the subject line (as the lists are
configured to look for admin requests and forward them to me). It
sometimes picks them out of messages when it is feeling overly
zealous.
Thanks,
Michael

Hi guys,
the "little primary noise" on MY triple was the broken mainshaft,
but usually it's the clutch rubber cush drive thingies...

OK, the noisy primary on *my* Jota was the tensioner itself which was worn and
flopping around like a sore duck.
I believe the RGS has a different piece than the older Jota, but it's worth
inspecting nonetheless.

I have sucessfully re-used this gasket, but only after installing a new
one using Hylomar, a non-hardening sealant. Check your crankshaft drive
sprocket carefully, you may find it loose on its shaft and the splines
worn. This happened to me. I got a new sprocket which removed some of
the looseness, and green Bearing and Seal Retainer Loctite did for the
rest.

Yes Marnix, I talked to him in early December when I was wrestling with the
prospect of buying a 3C RS. Very nice gentleman and very free with his
time and advice. He at first told me not to buy it as he felt I was too
small and light. After he heard the price, he said in effect, screw it,
for that price just go do it so I did.

Hi all,
Just a quick note to introduce myself to the list. I'm Stephen Battisson
and I'm from Canberra Australia, the Capital of Austalia and (more
importantly) the home of really great roundabouts!
I'm 25 years old and have owned my RGA since age 20. I've been riding it
for longer though as my Dad bought it new in 1984 when I could barely see
over the tank (got a good photo of this:-)). After years of pestering I
progressed from just riding pillion to being allowed to start it before a
run, then I had my first ride of it after holding my licence for a year or
so. I owned a few transient bikes culminating in a '90 ZZR-600 but I
always wanted the Lav. By '92 I had to sell the ZZR to help a pending
court appearance for speeding (bad Karma) but by then it suited Dad to move
on so a few months later I bacame the proud owner of the RGA1000 eng #2505.
I've spent many enjoyable years riding it around and nearly two trying to
rebuild it. After a 'facelift' in 92 (SFC1000 fairing & clocks plus new
paint etc) I fully stripped it in 96 to "give the frame a quick coat of
paint". A long and sad story of a rebuild gone wrong followed and it's not
finished yet!
To pass the time I've started a website some of you may have visited,
"Laverda in Australia" has been a great way of meeting lots of e-mail
friends from around the world who I keep threatening to visit some day- but
like everything else it must wait till after the bike is ruinning again.
So here I am!

Subject: Laverda Intro and Problem
Greetings all,
I'm a Techo at the Australian Netional University which happens to be where
Steve Battisson is as well, and I can therefore blame him entirely for my
affliction to Lav's. Over the last 8 years I have been able to observe both
owners and machines and develop an understanding of thier intrinsic
behaviours and about 6 months ago took the plunge, purchasing a SF2 with
12,000 miles on it (in a box sadly).
The rebuild is almost finished, and to put my mind at rest I need to find
out about the voltage regulator. I didn't recieve one in the box of bits
but was assured that the VolksWagon Beetle unit was virtually the same, as
it says in the "Green Book". The numbers are very similar(0.190.350.045 and
0.190.350.068 or thereabouts) and they are the same shape and size. The
differences however are the price and the current rating, around $275 new
&$175 used for the genuine item or $20 for the used VW item, which I intend
on using. The Lav one is 11 amps and the VW one is @28 amps and this is the
concern; can I run it?, will it supply too much current to the field
windings in the generator and cause problems?, will it over current the
battery and cause problems?, will it burst into flames and burn my balls
and more importantly the bike thus causing problems? or will it do
something totally unforseen(like work).
On the brighter side I have made my own wiring loom using multi pin Molex
plugs on switch blocks, ignition, guages etc and in doing so have redrawn
the wiring diagram from the Green Book, making it a bit easier to read and
use. I have also found two mistakes in the Green Book SF2 diagram; the
diode is shown backwards and the high beam indicator lamp is hooked up on
the low beam circuit. It's an Autocad R13 drawing and I will gladly send it
to anyone that wants it.
Ciao for now and thanks in advance.

Hi there,
I had the same trouble on my Lav 500 as well. When I bought it, I got a second cylinder-head with it, witch had already dropped a seat. After running the Lav500 for the first 1000 km, it dropped a seat
and smashed a valve. ;-))
I took down the head and took it with the "spare"one to a mech-workshop, to make the best of it.
The mech checked the "spare" head and found it so uneven (is this the right word? it was a bit bent), so he don¦t want to use it. ( Otherwise he would have machined it down und I should have put a sheet of alloy under the barrel to prevent the pistons fro
The original head was ok to him. He took out the old seats and machined oversized ones on a lath.
He machined the "seat-seats" in the head and shrinked the sats in ( a kind of hot/cold magic).
He just renewed the outlet-seats, the inlet ones seemed to be ok. He used a harder metal than the original seats, so I can run the little Lav on unleaded fuel.
The costs: he invoiced me with approx. 10$US per seat and 60$ for the work. so all in all 100$.
( 1 DeutschMark = 1.8 $ US )
I think this was very cheap. After rebuilding the engine, I had to grind down some of the shims to adjust the valve-clearance.
Now it¦s back on road and a good, revvy fun.

Hi Craig,
The current specs tells you the maximum current that the regulator allowes to be taken out of the generator. There¦s no danger to your regulator, wiring, battery or balls. Only the generator is in danger
when to much power is TAKEN from it. What can take to much power from the Generator? 1.) a defectiv or "low-on-charge" battery
2.) additional electrics like fog-lights, 100W-Stereo, AM-CB-set, a fridge, heated handle-grips or underwear
To workaround these potential troubles: 1.) don¦t use additional electrics or be very shure what you are doing
2.) mount a 10AMP fuse between the generator output (D+) and the regulator input (D+) to ensure theres no way to take more power out of the generator than allowed
From my point of view you can use the VW regulator. Add the fuse and you will be on the safe side.
There are "AutomaticFuses" which are resetable. I use them for years on all my bikes. Check out a electronics shop.
By the way, on my 750GT i ran VW-beetle silencers in the empty mufflers to get it street-legale;-)
It sounded horrible...
Cheers & good luck,
Stefan

I bought one too several years ago but after studying the item decided not
to risc 'fried balls'.
I used the shiny cover to make an old regulator look handsome...
Someone told me that regulators can be modified/adjusted but didn't try it.

Right!
> and the high beam indicator lamp is hooked up on the low beam circuit.
That is no mistake because my SF2 used to light it's high beam warning light
with low beam on and I know I'm not the only one! Don't ask me why...
Something else which I found out being completely wrong in the SF2 wiring
diagram is the wiring of kill switch/starter button.
Suppose you also cut out miles of excessive wires running f.i. from handle
bar via heart of the wiring above battery back to the headlight and vice
versa, same with horn etc. Saved me kilos and reliability gained.
Bye,
Marnix

I'd love to have the diagram, but as for mistakes in the green
book: I have a '73 triple and the wiring diagram in the green
book shows all kind of weird mistakes, but that is exactly how
the bike was wired when I got it (and the wiring was untouched
since new).
Examples: The turn signal circuit bypasses the ignition switch,
so the turn signal works even when the bike is parked. Imagine
your surprise when you want to take off in the morning and some
prankster turned on the turn signal the night before....
The generator light is connected to the turn signal. The high
beam light is connected to the low beam. The turn signal light is
conncted to the ignition. The ankle bone is connected to the
shoulder bone.
So your high beam-low beam confusion is probably factory
standard.
As for the regulator: Sorry, I'm a doctor, not an electrician 8-)

Now I don't know much about older bikes, but I've read articles
about magnetos loosing their magnetism. First sign is that their

Hello Chris,
If I shrink the digests then they will come out more frequently, and
the whole idea of the digest is to accumulate a fair number of
messages.
It is a balancing act - I get requests from people on some of my
lists to make the digests even bigger so they don't get so many (like
they get charged or tracked by the number of messages instead of the
byte size).
You might consider a different mail reader - I use the freeware
version of Pegasus Mail and that deals OK with the 100+ message
digests on the Ducati list.

Subject: Laverda Weekend update - SF2RR, 50cc GP Suzukis, racing Sprints, throttl
I started off on Saturday by driving to the foothills of the Sierras
and picking up a 50cc Suzuki engine that my friend Craig had been
converting to roadrace trim (kit cylinder, lightened crank, big carb,
close ratio gearbox, fully disassembled for the last 10 years,
multiple small cans full of jumbled parts, etc) - I got most of a
spare AS50 bike with it, as well as a pretty nice shape Vesco Rabid
Transit fairing, which will have to be considered for fitment to a big
street bike (the SP100 Guzzi maybe), whenever I happen to get one
rolling. I was also forced to take a working neon Suzuki dealer
window sign (about 16" tall with the late 60s style "S" logo) which
may be put on the market to defray some of my recent massive
expenditures on race bodywork stuff.
When I got to Craig's shop I discovered that I'd brought all the
engine parts for the Laverda except for the cam chain - so much for
timing the valves and fitting the piston valve pockets.
As it was, we ended up spending the rest of Saturday and about 8 hours
on Sunday fiddling with the body work (now painted - sure is ORANGE) -
drilling mounting holes in the front fender, making seat mounts,
trimming and drilling the fairing bubble (what a pain). We also got
the SuperTrapp discs mounted on the end of the new and repositioned
megaphone.
The paint (SFC orange, but a bit brighter than the rather muddy color
on the SFC side cover my friend Steve loaned me) came out looking
pretty nice. The painter did get the front number plate slightly off
center, but the tank (with a bit of filler) looks really super.
I'll get Steve to come by this afternoon and help me unload the 750
and get it on the work stand. Then I can start taking it all apart to
finish the engine work and repaint the frame and exhaust prior to a
(hopefully) final assy. I'll try to snap a photo of the loosely
assembled bike when I unload it - maybe I'll be able to get that up on
the site in a week or so if I can finish the rest of the roll of film.
One big problem is where to store the body work - I guess the back
bedroom is likely to be safe. I've never had anything sent out for
painting, so I'm a bit uneasy over having such nice looking stuff.
The pull on the 40mm Dell'Ortos on the 750 is really heavy (as in not
being able to pull hard on the brake at the end of a race due to arm
pump). It looks like a lot of this is caused by friction where the
throttle wire goes through the 90 degree metal elbows (needed to
clear the tank) into the carbs .
I made the elbow radius a bit bigger (by pressing a larger radius
socket into it in the mill vise), but the problem seems to be largely
a very stiff wire. A quick look through the Flander's catalog shows
that I've been using their 1.5mm 19 strand wire. They also list a 1.2
and 1.5mm 7x7 strand version, and the 7x7 strand clutch/brake wire is
annotated as being "extremely flexible". I'm going to order up a roll
of the 1.2mm 7x7 wire in the hope that by going to both a smaller OD
and the different construction method wire it will give a smoother run
through the carb elbow. I'll report back on this - it might be
helpful to other people suffering from the same problem. I've also
had trouble with the slides not returning fully when using the soft
springs - not a surprise now that I know how much drag was in the
cable assy.
The 3 races old Dunlop 591on the 750 has really hardened up over the
last couple year of sitting - good thing I ordered a fresh set of
Avons. I'll leave the Dunlop on until after the dyno tuning - no
sense wearing out a fresh tire when this one isn't going to be safe to
run on the track or street.
I really don't see being able to get everything done in time for
running at the Team Obsolete vintage races at the Laguna Seca AMA
national 04/18-19. I'm going to try and proceed as if I will be
going, but I've still got a mountain of stuff to do (besides going to
work during the day, shipping books and RITAs in the evenings, eating,
bathing, etc). I've got my entries for the AHRMA races at Sears Point
and Willow Springs sent in - I hope I get to make at least one of
them.
I also brought my friend Jim Connelly's spare 350 Sprint motor back
from Craig's shop (Craig is doing a head etc for Jim's vintage RR
project). Jim and another racer with a converted 350 street bike are
interested in upgrading their ignitions, so while I have it I'm going
to measure up the ignition stuff and see which RITA kit will be
easiest to modify to fit.

Hello to all!
I desperately need the name of a service to lighten and balance my 750

Subject: Laverda RGS/Witt Ignition follies, part 2
Well we got the loaner box installed, and still no spark. There is
10.5 volts going into the box. Is this sufficient?
Another discovery was that there was no input signal to the box from
the pick-ups. I removed them from their mounts on the timing plate and
passed a screwdriver over them individually. We got a voltage spike of
approx. 3V from cyl 2&3 and none from cyl 1. They all three had a
resistance of approx. .20 ohms. When I re-installed the pick-ups, and
checked output at the connector, again, no output. Perhapds a break in
the wires? I have them gapped at .030" and the rotor has 2 triggers.
This is an early box without a "test" position and in fact has no dip
switches.
I will be now returning it to Wolf Haerter with a sizeable check for
his long-suffering patience in my tardiness. This leaves me with my
original problem, could there be any substitute for the OEM pick-ups
which I believe are unavailable?

Any Laverda List members who would like to assist in creating a
Chassis geometry database please call me at 805-274-2453 during business
hours. I would provide this service free of charge to assist in the
preservation of these machines. This will entail parking your bike in
front of our Computrack machine for about 1 hour total and letting me
put adhesive stickers on the relevant locations.
I of course already have my RGS on file but would like to have at
least 3 of each model to ascertain factory working tolerances for
chassis manufacture. The completed measurement with exact geometry and
twists and misalighments will be then sent to this and other groups for
safekeeping and easy access. You would be very surprised just how much
actual geometry numbers vary from published data.
Anyone wanting to use this offer during the Willow Springs AHRMA event
let me know and I will make arrangements. The bike will stay fully
assembled with the exception of removal of the front fender.

You need to ground the triggers to the bike, before you test them.
Also you have not told everyone you are working with a Prototype box. I had
told you that the power feed needed to be clean. not hooked to anything
else. If I have time I well come over and help you with this problem.

Subject: Laverda Gemini
Hi Jim, yes I agree with Chris Rein in that the magneto components can
decrease in output with an increase in the working temp.
That is to say as the engine heats up the spark comes easier at the
spark plug which is common knowlege. But, as the electrical components
heat up the spark is more dubious. Hot components are at best iffy. So
if the spark actually is the problem I would look to the coil under the
flywheel responsible for spark and have it tested and rewound if
necessary. Of course it would be good to make sure the magnets are
strong as well.
All this is predicated on having a bad spark problem. Most of the time
the symptoms you describe point to a bad or diminishing fuel supply.
The fuel problems run this way in percentage order of probability:
starting with being out of fuel, poor to bad petcock flow, reserve
supply plugged up and the most elusive of all is the tank breather is
plugged up which usually produces the exact symptom you describe as
well. Best of luck with it and of course please let all know what the
problem was for our future reference.
Please let me know also if you located any parts sources for Geminis as
I need piston and rings for same. All the best, Lance Weil

I'm afraid so...
Remember their ignitions are $800...
Their fuse box (ultra trick though) weighs in at US$200 also...

Folks:
I had a serious crash/re-installation on AOL today, all my bookmarks
disappeared.
Could someone, at their convenience, post the URLs for the following:
The ILOC (UK)
USA LOC
The Laverda Australia page, including the "parts" address
The MGNOC
If my memory recalls any others, I'll ask, but these would be tremendous
for now.
many thanks in advance,

No. Witt advises to ground the box directly to the battery. If
your battery is full, why should there be only 10.5 volts?
(Unless you're cranking the bike over)

The tank breather problem is the easiest to check. As power goes
down, open your filler cap. Better running? Bingo.

Thanks for the reply! I had quite the crash this afternoon, like the PC
had a stroke! Lost all the bookmarks, etc. Was re-installing them as you sent
your note just now. I've re-marked your page, and read the article, which was
great! What a bike this could be, eh? Light weight, innovative structure, etc.
Thanks for a scoop I've been waiting for for a long time!

Good point Chris, the battery is new, less than 1 year, but has been on
a battery tender. I syspect that we have an excessive amt of resistance
in the wiring somewhere, possibly corrosion at a connector.

I know Peter well, in fact I talk with him practically everyday, I will
just ask him to fax the info along to me. If that is OK with you?

Subject: Laverda Intro
Hi all,
After beeing on the mailing list for about two weeks and sending one or
two comments, I want to introduce myself.
My Name is Stefan Schoeneberg, i live in the north of Germany close to
Hamburg (Hi Chris Rein, its only 150km!).
I¦ve got a 1970 LAV 750 GT for about 10 years and a 1981(?) LAV 500 for
about 4 years. (+a YAM/Velorex outfit, a MZ 250 and a Zuendapp 250).
I hope to get the 750 back on the road again next week after engine
rebuild due to a broken piston. Next project will be incrasing the
reliability of the 500. It¦s normaly ridden by my wife but because of a
baby-break she won¦t be on the road this summer.
Have a good time with your Lavs,
Cheers, Stefan

Subject: Laverda poor 500
Hi all,
I¦ve got a Lav 500, which is big fun to ride on the open road, but it¦s
annoying in town. After about one hour at low revs, frequent stops and
starting from time to time the battery is down.
Due to "hacksaw-tuned" carbs, the engine stops often at idle. And maybe
the poor Bosch BTZ doen¦t make things better.
- - Has anybody tried to improve the geneartor output at low revs ?
Its a 150 W Bosch-type with two leads output. The used rectifier is
non-stock.
Can anybody supply the Bosch-No. of the triples 150W alternater?
The green book says they work OK on triples...
- - The carbs ( Dellorto PHF 32 AD/ AS) were damaged by the previous
owner who tried to "tune" the bike. All internals are no problem,
I get them all out of the shelf. But complete carbs or just housings
seems to be unavailible or worn out.
The alloy stubs seem to crack easyly and I saw rubber/Steel ones on
500s in Great britan .
Are there maybe other carb/stub combinations and is anybody
experienced with it?
Thank you for any assistance,
Stefan

Hello Michael,
My experience with selling RITA ignitions for the last 7 or so years
is that about 95% of the ignition problems are elsewhere in the
electrices - low voltage caused by corrosion on terminals, poor
output from the alternator, duff batteries, bad grounds, etc.
All of the different ignitions I've dealt with are voltage
sensitive, and the RITA has a lower threshold of about 11 volts
where it starts acting weird.
Cheers,
Michael

Hello Stefan,
A set of Kei'hin CR smoothbore carbs would probably work a treat on
your 500 if you can afford them. They are (in my opinion) a
noticeably higher quality product. I use them on my projects (like
my Triumph T150 Trident) when I'm not restricted by vintage racing
rules from using them.
