750SF2 Project Ready for Assembly

[ksoholm]

Nearly turn-key project. Bike sat in a dry garage for 37 years and had 19K miles when I got it. I have spent the last two years refurbishing parts and buying nearly everything needed to start assembly.

The following is included:
- Powder-coated frame, swingarm, and other originally black cycle parts, including battery box, airbox, toolkit holder, instrument bracket, center stand, etc.
- Swingarm bushings in excellent condition.
- Engine rebuilt by Laverda expert Wolfgang Härter:
* Engine Dynamics rebuilt and blue-printed cylinder heads with new springs and valves.
* New Megacycle 5C camshafts.
* Ross Racing forged 10:1 pistons.
* Crankshaft checked.
* Engine cases vapor-blasted.
* All engine internals new if not perfect, including primary chain, clutch, new 10mm oil pump, all-new fasteners.
- New Ikon 7614 aluminum-body shocks.
- Stock forks need rebuilding with included Race Tech Gold Valves and fork springs, dust caps, seals, and steering head bearings.
- Wheels were vapor-blasted and need building with included bearings, German stainless steel spokes, new cush drive rubbers, and new brake shoes.
- New petcocks included.
- New stainless chain guard, comes with stock chrome pieces that need polishing.
- New front master cylinder. - Brake calipers need rebuilding with included Brembo rebuild kits. Brake discs in good shape, brake disc carriers were powder-coated and are ready for assembly.
- Electricals:
* New wiring harness.
* New Dyna coil with mount.
* New headlight bucket (needs paint).
* New OE Bosch voltage regulator, new starter relay.
* Refurbished handlebar switch shells, switches need assembly.
* New aluminum-bodied '71 tail light. * Professionally rebuilt generator & starter motor.
* All new rubber wire caps. - New solo-tool kit seat assembly from LaverdaParadies.
- New chrome front fender bracket.
- New Tarozzi-based rear sets.
- New Malcolm Cox chrome mufflers.
- All new steel fasteners for entire bike from Boltdepot included.
- New rubber bits included, like tank rubbers, etc.

All parts to be refinished have been degreased and are ready for polishing: Fenders, fork caps, various smaller aluminum pieces.

The project still needs the following items which are the buyer's responsibility:
- Headers, Wolfgang Härter has more coming.
- Gauges are at Wolfgang Härter's for refurbishing, bill to be paid for by buyer.
- Rust-free tank, side panels, and seat tail if desired, need paint.
- Carburetors; either Dell'Ortos from Wolfgang or Mikuni RS36s can be ordered.
- Carburetor cables.
- Electronic ignition, like Witt, recommended.
- Tach and speedo cables.
- a few other small odds and ends assembly progresses.

I have USD 11,000 into it. Asking $9,000.

This is the foundation for a mint, better-than-new, cost-no-object, SF2. My price is what I have invested so far. Sorry, I cannot ship.

Choice bits. What's the reason for sale?

 

[ksoholm]

Well, I have three old bikes, but really would like one modern one for straight utility - as simple as that, really.

Looks like a high quality refurb/upgrade Kristian. Anyone after a really good SF2 could do very well with your bike.

One point I'd make is that a 5C cam won't function very well with stock mufflers (tried that when I had to take my bike with the 5/C through registration so fitted the std system minus crossover to quieten it down - totally gutless) - a stock 7/1 SF2 cam will give you better performance at any rev range than a 5/C without a tuned exhaust. Not that that is your concern.

5C cam lift doesn't agree with SF valve springs. They become coil bound at high revs.

No they don’t. That’s the 6/C.

[Tippie]

I raced for years with 6C and std SF springs without problem, must be a close tolerance thing.
Why would they coil bind only at high revs?
For sure though a 5C is not recommended without tuned exhaust, and best with higher comp and degreed in.

 

[CLEMTOG]

something not adding up there Tippie, for the 6C cams the springs are wound from thinner gauge wire, dont ask me how I know, couldnt even turn the motor by hand when discovered and aided, with information, at that time by Marnix, good job the starter never came into play, it was a long time ago and I now know much more about valve piston clearances and have built up lots of motors with plasticine, just to check and be safe.

The springs for the 6/C cam had less windings, that’s why they don’t bind.

Marnix

 

[Paul Marx]

No they don’t. That’s the 6/C.

Marnix

I tested with a 5C, SF valve springs didn't like it. Symptoms disappeared as soon as I put 5 coil valve springs in.

Because it's at high revs that they bounce the most.
No problem in the High Street.

I would simply love to have this project. I hope it finds a good home right away. I just bought a Jota in pieces from Arizona and a Montjuic in pieces from Nova Scotia. Shipping a motorcycle in parts requires careful planning, but I think assembly is much more than half the fun. Good luck Kristian.

Do the springs for a 5C cam work with a 6C cam?

Jim

 

[MarnixSFC]

Do the springs for a 5C cam work with a 6C cam?

Jim

No they don’t, they will give the binding issue.

 

[helicopterjim]

No they don’t, they will give the binding issue.

I think I need some new springs. Good thing I'll be talking to Wolfgang today.

[Paul Marx]

Do the springs for a 5C cam work with a 6C cam?

Jim

They don't work with a 5C either

 

[helicopterjim]

They don't work with a 5C either

What about small valve heads? If I put my old 5C cams in the small valve head will I need 7C springs?

Good info, thanks. I'm going per Wolfgang's recommendations - 40mm crossover headers with the pretty open silencers. Have thought about the 2-1.

I might keep it yet; it feels like selling a baby.

Then this bike will complete your triumvirate!
