I use Givi bags; I like them a lot. My one criticism is that the
aluminium castings that the side cases click onto aren't quite
up to coping with the vibrations from an SF750 - I've had them
crack twice now.

Spares are easily available however.

Is that 'B' for Boyer?? In that case it's Phil Todd of Todd
Laverda.

It's very much cheaper than the Moto Witt system, but it isn't
programmable or anything.

His system is based on the newer 'micro-digital' red Boyer
boxes; I have this system in the Jota and it works OK. For the
180 triples he uses two boxes; one to fire the outside cylinders
and one to fire the middle one.

I do have one problem that's ignition related; when I take
it past about 8200 then the bike starts running very ragged
and strangely the Pichler eletronic tach goes right off the
scale. Below that it's fine. However since it did this even
before we put Toddy's box in I don't think that's the problem.
Pickup maybe.

There's much work been done on the Jota over the winter;
I may switch to a Witt box if finances permit.

It looks like Robert Milders' system had some troubles last night.  
I've unsubscribed him until he can get things sorted out.

Safari SITREP:

         Still deciding....SFC1000 or RGS.
Is the SFC a 180 while the RGS the 120?
Is there a book, a la Mick Walker's guides, regarding Laverda?
Are there any pix/reviews online for either?

Reasons I ask; when I owned the Jota I paid most attention to that and the odd
750 in my mechanic's long-gone shop. When the Jarama, 1200's etc. were
produced I really didn't give much time to 'em.

                                        comments truly appreciated,

They're both 120 motors in the newer frame. Differences are, the
SFC has a tuned motor (forged pistons, F1 rather than A11 cams, hand
finished head), higher spec brakes and suspension and different
bodywork.

The SFC is better for sports riding, the RGS is better for touring
(mostly due to the fatter seat).

There's an "RGS Corsa" with the tuned engine and better brakes that's
the best of both worlds but they're very rare. I don't know if they
ever went to the USA...

There's much, much more of a difference between the 180 bikes and the
120 bikes than there is between the RGS and the SFC.

Subject: Laverda New to the list.

My name is Steve Miller and I own ( am owned by? ) 2 SF 750s. One is a 72
which I ride on a regular basis. The other is a 71 set up for period one
vintage racing. I have been testing and modifying it at track days last
year and hope to campaign it at VRRA meetings this season. Below is a brief
description of the track bike.

Engine:   
Total professional rebuild including the following:

SFC 6C Cams
SFC Rockers
SF 2 Inlet Valves
SFC first oversize 74 pistons ( polished, contoured and measured for valve
clearance.
Head ported and matched to 36 mm Dellortos with Malossi stacks.
New clutch plates
New SFC clutch springs. 

Ignition:

DMC electonic ignition system.
 SFC ignition switch

Brakes and Chassis

Ferodo Green Linings
Needle Roller Swing arm conversion

Exhaust
New SFC 2 into 1 Racing Exhaust

Bodywork
SFC Tank ( fibreglass) including round Moto Laverda Breganze decals
SFC ( replica) seat unit.
SFC ( replica) fairing
SFC fairing brackets

Controls
Tarrozzi rear sets
Tomasselli clip ons and grips
Magura levers
Smiths rev counter with Laverda logo

Tires
 Dunlops.  


One problem is that a friend of mine who has owned a 1978 Ducati 900 SS for
12 years and who promised me that he would give me the first refusal if he
ever decided to sell it, ( I never thought that he would, but a serious
heart attack and the resultant surgery changed all that ), recently called
me to ask if I wanted to purchase it. I wanted to and did. This instantly
used up my racing budget for the next few years.
If anyone is interested in photographs of either bike, please e-mail me.

Cheers
Steve Miller

Haven't seen any books on the newer Laverdas. You might try one of the
magazine search places like Motorcycle Memories:

http://www.motorcyclememories.com/

They have a request form on their web site and have a bunch of stuff on
Laverdas available.

Nobody has them. Wolfgang sold a set for about $350 maybe three
years ago. It was the last one I ever heard about. If anyone has
a used set (right shift) he wants to sell I'll take them anytime.

There was talk about reproductions (by both Lance and a dutch

Doesn't the tach get it's erading from one of the coils? That
would suggest some problems with the coils...

Hi guys,

maybe something is wrong with my triple, but I ground the right
side a lot (been through more than one alternator cover, the bad
part is that the cover will shift up because it's only held by
two screws and then the alternator will grind through it from the
inside also).

It has nothing to do with riding foolishly, it happens easily in
very slow corners, like going up mountain passes, going like 25
mph in a very tight corner. I have grounded the center stand on
the left on my second day on the triple, going about 70 mph and I
have been very slow around left handers ever since.

The problem got a lot worse when I started fiddling with the
suspension (softer fork springs and real rear shocks). The
ride gets great, but when the bike actually gets lower
because of supension sag, courtesy of White Power instead of
Ceriani, it becomes a pain to ride around very curvy roads. I was
back to the original setup for a while, but that's not a good
solution either. I've already obverbraked the front twice on
bumpy roads, because the front wheel just skips around instead of
soaking up bumps. The bike is remarkably stable bouncing through
corners, but when you have to brake hard....ooops.

I am still musing about a way to get the right side smaller
(other than fitting a 1981 180 engine). What I want is a belt
drive with a nice, soft light clutch in place of the stupid drive
cushion thingy and a big alternator in the space where the clutch
now resides. Right side would be pickups and starter only.

Bye

Chris

Gotta check, maybe they only have 180 ignitions. They are a work
of art, but cost around $850 (including rotors, pickups and
coils). They also have a great regulator and rectifier combo plus
a VERY trick fuse box with automated fuses (just turn of the
ignition to reset the fuse) plus a turn signal relay switch plus
a 400 W electronic relay (starter/horn). These items are very
expensive also. They also supply replacements for the old Bosch
pickups.

Check out the german language part of their site, at least you'll
see the pics.

Hi Zottel,

I have found out more by speaking directly with the manufacturer. He is relocating
business and hopefully will be in production in the next few months. The unit he has
developed has been trialed for 2 yrs in a RGS and there have been no problems. No
units currently available for 180 engines and it is possible that units will be sold
in the US sometime.

Anyway it sounds hopeful -  but what about us Jota owners!!!

Michael:
My racer is all set to go together but my crank is still with Craig so I'll
miss my first two race opportunities. If I get desperate I might put a stock
crank in, but I dont really want to do that. While I have been waiting I have
been looking at ways to reduce engine weight. I am thinking about machining
off the center teeth of the primary drive gear as well as the center row of
teeth on the clutch hub, drilling out whatever looks 
possible on the clutch hub, and using two single chains instead of a triplex.
I assume they must be available somewhere.
While examining the clutch hub I noticed hair line cracks emanating from the
rivets.
Out of curiosity I checked my stash of four other clutch hubs and found that
only one unit seems free of any hair line cracks. Check yours. Do you think
this means anything?
Also do you use the preposterous "oil filter" ? Since the oil is changed so
frequently I'm thinking of retiring mine. I am also putting a new oil drain
plug under the shifter box for quick changes because I have a two into one
with a collector directly under the oil drain which makes for a lot of trouble
in the pits. Not only do I have to remove the exhaust system to change oil but
re-safety wire the four small bolts.

Regards, John
Also - my Ducati dealer has taken on a MZ/Laverda franchise. I'm dying to see
how the new 750s stacks up to the impossibly beautiful 748. Could be trouble
for my bank account.

After a weekend (mostly) in the garage I've come a bit closer to 
assembling the Laverda 750 engine.

For those of you tuning in late, I'd been originally supplied in the
mid 1980s by Roger Slater with a set of SFC Electronica pistons,
which are a couple millimeters shorter in deck height than the
SF2/early SFC pistons.  Not knowing about the different piston
heights I had shortened the cylinder block to fit them, presuming it
was very out of spec, . 

A new set of JE pistons was obtained from Lance at 1-800-LAVERDA last
summer, and after shortening them to fit my shortened cylinder I ran
into valve pocket to upper ring groove interference problems when
opening the pockets to fit the new  and bigger titanium valves. That
occurred the week before the AHRMA national at Sears Point in August,
and seeing a week's vacation effort go down the tubes at the last
minute put me off working on the engine for several months.

I obtained another set of pistons from Lance recently, and started 
setting the engine up to use them with the stock deck height.

Inspection of the cylinder spigot/head counterbore showed the spigot
to be about .012" taller than the head recess was deep.  However,
when a compressed head gasket is installed (.042") there is a .030"
(.75mm) thick ring around the combustion chamber.

I'd decided to ignore this, figuring the volume of the ring made at 
most a tenth of a point of compression.  I spent much of Saturday 
morning cutting new base gaskets and aluminum shims of varying 
thickness to set the squish band.

I got things set where the smashed solder was showing a .035-.040" 
squish clearance, and called my friend Craig to mention that I had 
made some progress.

Craig was very concerned about the gap between the spigot and head,
pointing out that it could be the cause of some detonation at some
point.  I was all set to ignore the gap, figuring that every Laverda
750 seems to be set up that way (and not wanting to spend the time
to fix it), but I've discovered that when I ignore expert advice and
something goes wrong I feel fairly stupid.  Craig told me today that
in a chat with John Symonds he mentioned this, and John told him
that Todd Laverda in England also thought it was worth fixing on
bikes they set up.

So yesterday evening I spent an entertaining 15-20 minutes squaring
up the head on my milling machine (it would be nice if they could
work some sort of fine adjustment into the gears built into the mill
for this purpose - trying to chase the last thou or two gets
frustrating).  I decided to take enough off of the head surface to
give a .004-.005" clearance with the compressed head gasket.  Since
the spigots can't be lapped into the head (unlike a Ducati twin with
separate cylinder heads), and the depth of the recess varied a
couple thou depending on where I measured, (and I didn't want to
bother taking a cleanup cut on them and the top of the cylinder
block seemed to vary slightly too and I didn't want to remove the
sleeves to true that up), I figured that a slight clearance would
ensure the head was still clamping up on the gasket and not the
spigots, yet wouldn't be significant in re the detonation problem.

After letting the mill run at a dead slow table feed for 7 or 8 hours 
I finally got to that point, so now I can start redoing the base 
gaskets to reset the squish.

The painter has primered the Laverda's bodywork and I have hopes that
the color (SFC orange of course) will be shot in a couple days. My
next task for this week is to clean up the cylinder head, install the
new Megacycle cams, and set the cam timing (on a cylinder with no
piston - saves bent valves).  Then if the paint is done I'll go up
to Craig's shop this Saturday with the engine and have him assist me
getting the valve pocket clearances sorted out.  That will finish the 
engine stuff and let me collect the bodywork and chassis to bring 
back to San Francisco to finish assembling everything.

Once it is assembled I'll have to organize a dyno session and see if
I can find a track day so I can set up the suspension (reminder to
me - build front and rear stands before the track day).  If I'm
diligent I may actually get things done in time to catch the Team
Obsolete vintage races at the AMA national at Laguna Seca, which
will be a good warm up/shake down for the AHRMA nationals the next
two weekends.

I've got the feeling that I'm not going to have time to get the CR216 
Honda put back together for those races - oh well.

What's the deal with the race promoters scheduling races before
June, the time when the season really should start (and I could
conceiveably be ready to go)?

Tim Parker announced an updated version of the 'Green Book' more than a year

He also announced an enhanced re-print of Ainscoe's Laverda book but this is
not very technical of course.

Hope we will see these soon!

I haven't talked to Tim Parker the last year, anybody been in touch with him

Drum brake SFCs had the old type heavier rockers yet they were made lighter
and they were polished.
16000/17000 batch SFC had the lighter type but these were SF items, and not
polished.
18000 batch SFCs had same yet these were polished and made just a little bit
lighter.

So on the rocker side SFCs are not really special....

The 'dutch guy' would likely be Gijs van Dijk; he does have
rearsets but they're CNC machined thingies and not replicas 
of the factory sets.

I spoke to Lance about his copies a while back; last I heard 
he was still wondering if there would be enough sales to justify 
the cost of making the castings. I gather that's the expensive bit.

As it happens we got the last set of factory rearsets for the 500's
for Janice's Montjuic!

Hello John,

If you can use the stock crank I'd recommend you do it.  2 races will 
give you valuable bike and self shakedown time, and you should be 
able to swap the cranks out over a weekend without problem.  The 
extra track time seems to make a big difference for most people - 
more valuable than an extra bit of motor performance.

I'd like to do the twin chain as well - an SFC racer told me about 
having his triplex come apart at high speed at Talladega with 
unpleasant results.

It means something more to worry about.  I really don't want to take 
the bottom end apart to look at the clutch.  Maybe there would be a 
small market for a batch of strong alloy hard-anodized aluminum parts 
if it is a known problem area.

I do use it - think of it as something to keep trash out of the oil 
pump, rather than an actual oil filter.  I've thought of tapping into 
the case as per the Electronica to run lines to an Oberg filter, 
especially as the race crank oil slingers were almost silted up to 
the point of blocking off the crank pin oiling hole when the crank 
was first pulled from the engine when I got it.

I had one of the two chains on my SFC Thou' go; I only found it when
I took the primary drive cover off to see what that tiny tinkling

You can drop the oil easily by loosening the gearbox side cover and
leaning the bike to the right. 

My street 750 has a 2-1 pipe which blocks the alleged "filter" ;-D
and I find this a quick way to change the oil.

In my experience, the shifter box is about the best place to drain the oil
because made metal particles settle down in that part of the engine. I have
a plug under the shifter box on 2 of my 750ies with magneto which catches a
lot too.
The aluminium is a bit thin there so if you want to do things properly it
would be good to first weld an aluminium ring on to give the cover more
meat.

Not true! Corsa has 280mm floaters, SFC has 320mm = better squeals.
Combined with superior M1 Marzocchi forks, and a decent fork brace as
standard, the SFC should better.
But then, I 'm biased.

Hmm, not sure. I reckon there's more variation depending on who maintains

comfortable you'll be bored. Oh no...

Fellow Listees,

thus far batted "Zero".  So I have decided to incorporate making
somethru my contract with J&E for other Laverda pistons.  So I want to
ask in reverse and see if anyone out there wants some 200cc Gemini
pistons?  
Please let me know as I am about to order them and will order a quantity
accordingly.  Please order a minimum quantity of Two Pistons.  They come
complete with rings and pins and circlips at $115 US each.  
P.S.  I have tried Andrighetto and others to find them already.

 Which reminds me... the primary chain side of my RGS has been rather
loud lately.  It has made some amount of noise as long as I've had the
bike, and careful fiddling with the tensioner has never made the noise 
really go away. (Tighter and I get a worse sound, clutch bearing perhaps?
looser and shifts become chunky) I've been meaning to pull the cover this 
winter, but I've  been putting it off. What are my chances of being able 
to re-use the gasket on that side?

It looks like we are just under 60 subscribers - surely far more than

Craig tells me the painter delivered the bodywork for the SF2RR
today, and it looks very nice.  I'm sure it will be nice when
assembled, but I don't know if I'm going to do something of quite
this magnitude again in the near future:

HD-XR750 fairing and bubble, 72 hours of fiberglass guy's time
(fairing ducting, new seat and fender (including molds for all
that)), paint and painter's time  - grand total about $1600

This is the first time that I've had anyone do painting on a bike - 
I'm going to take plenty of pictures before it gets started/ridden, 
just in case.

You're right; but I mean that the Corsa has better brakes than

I suppose I'm bound to have the most extreme view; I have a very early
180 triple (1974) and a latish 120 (1987) so the differences will be more
pronounced.

Incidentally, are you bringing your 750 to Cadwell in September? I'd be 
VERY interested to hear about your experiences; it's on my list as a
possible race bike for '99. Not high on the list alas, it's pretty 
expensive for the performance you get.

I disagree but it depends if gasket cement was used the last time and how
careful you are taking the cover off. Tap around the cover with a hide
headed hammer and you will see it come off with the gasket in tact.

I very often see Laverda engines where gasket cement was used and I really
don't understand why they do it.

The side covers fit so well on Laverda's that even after re-using the gasket
many times it probably won't leak.

Always good to have one as a spare of course.... :-)
