Ducati 350 MK3 Desmo - Silver Shotgun




1972 Ducati 350 MK3 Desmo - Silver Shotgun

 

The MK3 was the penultimate model in the evolution of the Ducati single development started in the mid fifties with the 125 sport.

 

This model was produced during a 2 year period from 1971 to 1972, it was based on the Mark 3 with light chassis mods, an all fibreglass bodywork set including tank, with silver metal flake finish integrated into the gelcoat, plus rear-set foot pedals and clip-on handlebars.

 

This model was baptised very soon as the “Silver Shotgun”, being that it epitomised all that was considered true cafe racer style, looks and performance.

 

Sold in 250 350 and 450 cc engine sizes, many prefer the 350 version for its well balanced engine : low end torque and high end power delivery.

 

Few of these bikes were made, around 2000 combining all engine sizes, few being sold in the UK at a time when Japanese bikes swarmed the market.

 

This bike was originally imported to France, French import plates date the bike as a 1972, plus it has a new homologation number making it the 40th bike produced after August 1972, one of the very last to be produced.

 

I purchased the bike in late 2018 as a parts lot, semi complete, and have managed to accumulate all missing parts during the rebuild.

 

The engine has in my view never been rebuilt; it is interesting to note that I found the remains of a ripped off engine seal wire in one of the Allen bolts under the engine in the process of the build. I have completed a full top end rebuild - as can be seen in the image bank the valve seats have never been re-ground mechanically and are in very nice shape, I replaced the inlet valve, all bearings and seals. Desmo head valve clearances adjusted with correct shims to factory settings. Sludge trap in the crank flywheel has been emptied; I’ve changed the plug for an allen head version for ease of removal, oil replaced.

 

Motoplat ignition timing is set to the marks on the engine casing using a strobe as recommended in the factory manual, Dellorto VHB 29 AD Carburettor is mounted with new seals and cables, throttle grip is the correct Tommaselli Daytona. A new (Conti) exhaust pipe is mounted to a newly made Italian Silentium unit, as original.

 

Handlebar controls are all original components with new cables fitted. Original equipment rubber Tommaselli handlebar grips. Original rear-set foot pedals and accessories have been zinc plated with new rubbers added.

 

The frame has been checked for straightness, cleaned up and stove enamelled satin black, with NOS Nieman steering lock and original ball race headset bearings. Marzocchi forks have been dismantled, cleaned with new seals, dust covers and oil replaced. Swing arm bushings are in good condition and are original, new grease nipples have been added, original pivot grommets are present. Rear Marzocchi shock absorbers are rebuilt original units with new seals and oil, working perfectly with no leaks.

 

Wheel hubs have been bead-blasted, new bearings fitted, new as original zinc plated steel spokes assembled to polished original Borrani WM2 x 18” rims. Tyres are new Dunlop TT K82.

 

The original panels that came with the bike were too far gone to be of use, front mudguard warped by age no longer fitted the bike - a new Italian made panel set has been used for the restoration, the metal flake has been tempered with a satin varnish for a more period look and feel.

All chrome work has been re-done to better than original standards, all ancillary steel parts have been nickel plated as original.

 

Original Aprilia headlamp and lens, containing original electric components - all working correctly using a new wiring loom. 4 contact ignition key that came with the bike was broken and has been replaced with a new copy. Original rear light unit sourced, with NOS lens. Correct NOS Veglia 120MPH speedometer and original Veglia racing tachometer are fitted with new cables.

 

The side stand visible on the bike is from an RT/450 US market scrambler and works perfectly, the original centre-stand is available, but will not fit alongside the side stand so a choice is necessary.

 

The original side panels and front mudguard can be made available to the purchaser - to be discussed at the sale.

 

I am a passionate amateur Ducati Single collector and restorer; I believe in the quality and performance of the original equipment on these bikes. As a collector I cherish authenticity - this Ducati 350 Desmo is a revival as much as a restoration, I have made every effort possible to retain all period quality, and with this aim have used original parts where at all possible. I am selling it with some regret to make way for future projects. 

 

A DOC UK authentication certificate comes with the bike as do the French historic vehicle authentication and registration papers, and various receipts for new parts used in the project. Since many of the original parts used on the project have been purchased over an extended period of years from other collectors and enthusiasts, there are no receipts for these rare and difficult to find parts.
