New member and thanks...

After Soaking in Diesel Fuel for a day or two, Spray some Red Rust Check on the critical areas, wrap it Alu-Foil then bake it for 30 minutes in the Wife's Oven at 200F.

It should fall apart using Rust Check as a Lubricant.

If the Wife gets curious, say your basting a Turkey and when she says what happened to it - Say you messed up and had to through it out - Been there done that - LOL
 
Whatever way you like it - LOL

And if it don't work the 1st time do it again with a little more heat, just make sure the Wife's not around.

But I'd advise to buy a pre-cooked turkey before you attempt it the 2nd time.

Sooner or later our Wive's find out that us Breganze Guy's are a Sick Lot.

By the looks of your pic's and from what you tell us about rust a seizure, I doubt you will be able to save the valves and the guides. You may be looking at a fair amount of money for Guides, Valves and Seat Resurfacing - You will not know until you see and spec them. For starters buy new Valve Springs, Gasket Kit plus the Green Book from Wolfgang. The Cam, Cam and Rocker Bearings will probably be OK. Just hope your Main and Rod Bearings are not afflicted. It's good to have access or know someone with a Machine Shop. In most cases when I see this, the Valves are just too rusted or pounded and after resurfacing there is no Margin left; therefore, new over-sized Valves with Guides are required plus regrinding of the seats. If your Lucky they may still be good for another 50,000 klics.

One thing I must say is that the original Laverda gaskets for the covers are excellent and if in good condition better then any you will find in a kit.

James, if you need help with concrete I'm your man,

apart from our attic time of course  :P

Ciao Cosi,

Thank you for your recent email, excuse my ignorance in failing to reply. Life has kinda got in the way of things during the last few weeks. Latest googly being a significant change in employment status becoming imminent rather than foreseeable in the near future... Indeed I has as yet failed to progress the 750 S acquisition, I would be shocked if it's cover has moved since I went to take a look see and hey, there is no hurry anyways.

I must also thank you for your very generous offer in regards to concrete. To date my requirements have been pitiful in the scheme of things, landscape gardening mainly. My father can no longer help with concrete advice now as he afflicted by end stage Parkinsons, he was a geologist who specialised in soils sampling and materials testing for civil concrete structures. What he loved best was the analysis of failed and failing structures, revealing the causes and providing restorative solutions if possible or in the case of failed; a specification requirement to prevent recurrence. Ironic that most of the structures he was involved with in Dubai have been demolished by city has grown out of all proportion of the last few decades that shed loads has obliterated to make way for bigger, better, smarter and more expensive... none of them had time to fall down!!

Before I mention "our attic time" I would like to remind you that my 'emotional needs' are amply met by  ::) more than enough locals, whilst keeping "Monaco" (who is currently in Paris) on track. Her husband, whom I've known a long time (since before I acquired my Jota), is a truly wonderful man, so many brilliant stories, all of which are true, many of which are simply hilarious. Bless he is now rather elderly and has started that journey of ticking off a few important good byes.

Now about "our attic time": I am sure that you said that you wouldn't say anything about it if I didn't say anything about you saying anything what I said. It is possible that I became confused? It happens...

Any roads, I has been driving a confuser for far too many hours today, interspersed with a liberal quantity of quality 'Davi Guzzi' riding time so will retire to neck another quality OTB brew, roll a number and kick back in front of the weather forecast to see whether we is gonna get another day or two of "summer"  :) It's a remote concept round about these parts... Trying to think when we last had one? '76 was good and there was one during the 80's IIRC. Per Erik and Ase have had a blinder so far in Alta this year...

Toodles for now,

ciao,
James
 
Back to the originally thread/topic whatever...

Bob,

I think you have a flavour of what real world participation of Laverdaisti family life is about. All of the characters who have posted are real people and really we are not a big community, thousand or two maybe? Like all families there are occasional squabbles over nesting sites. Among the more active and globally mobile members of the 'family' almost everybody knows everybody but we don't do ridin' o' Vespas, Morris Dancing or incest... unwritten taboos or do we?

Make life easy on yourself. Get the engine on a bench.

Maybe 10 - 12 year ago I got a mongrel SF something. It required too much work and was a mongrel, it has help others...

My American Eagle was delivered coming up 7 year ago. It was in a state that wasn't South Dakota, you are starting from a better place.

I do graphics for a living, I am not an engineer. Piet, Redax, Nairn, Todd and a lot more besides are. Trawl the site a little and you will soon learn whose advice is worth following.

And as I said before.

Have fun.

It's worth it  :)

James
 
Ha Ha!! Good luck with it Bob.
Making sense of this place i mean.
The bike won't be a worry in the world.
Where are you by the way?
Bomber
 
I'm located in the Midwest USA, Kansas City area.

This bike has been in the family since 1979, bought second hand from a big dealer in the Dallas Texas area.
Back then of course an owner could get stuff done on their bikes at the shop if needed.
Now depending on location we're more dependent on mail/internet order.

This SF2 was moved from Dallas to Miami with a job change. Last Florida registration was 1995.
Then the bike was in garage storage until another job change left the bike stored outside for the last few winters.
I think fuel seeped from the tank through the carbs into the cylinder head and evaporated. Maybe some water in through the
carbs as the rubber boots to the filter box were removed. The carb bowls showed evaporated fuel crud too.
The fuel tank is not rusted inside.

My intent for this recent work is to get the engine crankshaft to turn. So I have started with removing the head. The cylinders are next.
Then as strongly suggested, split the cases for inspection.

This bike when running was great for the open highway. But as an around-town commuter not so much.

I need to get a 6mm tap to clean up the threads in the rocker spindles then I'll pull them and get some photos.
The ATF and solvent mix did help loosen the carbon built up in the head.



 
Bob: Nice to see another 'Murican (or, as the like to refer to us on this site: "Yanks"....or perhaps worse) on the site. I am in California, and you are the first Kansan I am aware of on this site...I have had a couple of SFs and Jotas, and now have an SFC and JOTA. Things to keep in mind about this site:

A.  A very motly mix on this site. They like to fight amongst themselves, and "pissing" matches break out constantly.

B.  Most of the mechanical advice is quite good. Some will exacerbate existing problems, and some will even cause mechanical breakdowns. As stated above a little studying and you will soon acquire the proper filter to guide you.

C.  Some members on this site (and you know who you are) are afflicted with "rivet counteritis"....you will soon have a much deeper appreciation for this term once you have put in some time....just file it away for now....

D.  Americans are a distinct minority on this site....the factions you have to watch out for are the Aussies and Pommies, they tend to group feed....

E.  Don't ever opine that anything other than a Laverda is absolutely the ultimate expression of motorcycle art.....just trust me on this one.....

Now, you have come to the right site, and you sound like you already have things figured out, you just need calibrating, so all will be fine in the end....
 
Hi Bob,
I must apologize for the way your thread got hi-jacked, I have split the topic and sent all the posts after this point to the rubbish bin.
We are all generally a lot better behaved then what you may have read in your thread.

Good luck with your SF rebuild, after so many years of ownership am sure you are quite excited to be delving into the inner workings of your engine with the view of returning the bike to the road.
As others have said before this post, just pull the engine out, you will find it so much easier to work on and with the engine out it gives you the opportunity to do some clean up work on the chassis.

Welcome to the forum

Red,
No worries with the deletions.

Bob,

You are not far from Scott Potter, hook up with him. Wolfgang in BC is your most local parts guy and will sort you out well.

I repeat, have fun and enjoy.

Hugs,
James
 
Good call Red. The idea of another mighty Laverda refreshed and doing miles is way better than where the thread was headed..

8)
 
Don't blame you for pulling the thread Red, just a pity it had to come to that :(
 
I totally agree, in the interest of the Forum to "Delete the Crap" and there's a lot more crap that should be deleted but I warned you EU Guy's to be friendly, don't push us North American Berganze Riders - That's where differences can HURT.

There you go BobyZ - Good Fortune with your SF and suggest you get on the phone with Wolfgang, he's just next door.

After your have inspected and if you have determine the the Seats, Valves and Guides are shot: PM me and I'm sure we can design something better, working between us, a machine shop and Wolfgang, leave the EU out - They're out touch and too costly for us.

I can rebuild a SF in about 3 months during the winter months, including the Frame and paint, living in a 2nd story apt then wheel her down the steps when I'm finished. Then I got a month of cleaning the apt  - LOL - Nobody can afford my hours but I'll teach you how to do it ;o)

I'm 65, separated, raised 6 children, a Class "A" Mechanic with a an Engineering University Degree and have been riding since I was 14. My 1st Bike was a 650 BSA Lightning at 15.

I noted you had to cut the timing chain - Order one from Clem and pay the postage - He's into Chains.

Is this considered Soliciting?

it is Andy who sells chains, aka Andy Chain

don't believe Clem is into chains at all unless he does chains when he goes to his BDSM nights  :o


Bob, Wolfgang has every part you need to rebuild your engine, just contact him but not for next 10 days, he is holding his Laverda rally this weekend I believe and then he is going for a 7 day ride
is nearby in Canada, well stocked in parts for all models, good prices, very nice people Wolfgang and Margo, great service
