ISOSCOOTER 150 / F
What I am about to describe is the recent story of how I attached to my Isoscooter a copy of the Diva (Permit me to call it simply the case, although the official name is Scooter Motorcycle ISO 150 / F, according to a card approval in 1960, IGM 1303 OM). In October 2000, ISO already hopelessly infected by the universe, I went to the international gathering in Bresso Isomillenium with the whole family. On that occasion I was fortunate enough to greet and shake hands with family members present at the event Rivolta, I could talk with the engineer. Rays (Designer Isetta and the various Gran Turismo), enjoy the family collection Ghezzi, great fans and connoisseurs. I saw excited Piero Rivolta un'Isetta lead with his mother for the square in front of the building industry, accompanied by a smile and welcomed by thunderous applause of those present. And finally a fleeting visit in the former factory and built the underpass to access the area where once there was the track of the tests. The event was marred by bad weather but the investment was large with massive presence of foreigners who love the powerful four-wheel, and to expose the original ISO-Marlboro / Ford Arturo Merzario.
Finally I was able to see live (and hidden touch) motorcycles and car production Iso, taste it although the short evolution. All models produced by Iso were represented by Ferret ISO 125, dall'Isomoto 200, dall'Isetta all'Isocarro and more.
But of all there was a scooter that I had never seen before, exhibited for the occasion by Ghezzi, an elegant ivory and red, a little 'and a little Vespa' Lambretta. Actually it was more mortified by the comment that they preferred to dwell and other models. Thus was born the desire to own a Diva, this is his name, and dreamed about how he was handsome with his 150cc engine. Shared it with my wife and I discovered that she had seen and liked very quell'autoadesivo applied Right on the shield that depicts the figure of a girl on the scooter with the dog that protrudes from the trunk. Well a year later, while I was in Ferrara from a Lambretta spare parts dealer, I recognized among so many old Lambrettas neatly arranged in a row under a shed the outline of a Diva. I asked for information and I was told that had happened to be there because the owner thought a scooter to get rid of Innocenti and they'd be very glad. Indeed nearby there was another, but without a first set of documents and incomplete. The sample on which I had talked it was instead of a second series of '59 with all the documents, (later I learned radiata office) Targa Bologna and truly complete with all its parts, the engine was not stuck to the pedal and had good compression, ivory / blue, was the Diva for me. In December 2001 the scooter crossed the Po
From the pictures did not seem bad, in fact, the body had no visible rust problems, but under the platform where it is exposed to dirt needed radical intervention, bonnets and front fender was repainted in the wrong color and began to peel, the ring of the lighthouse had several cracks, the para has been realigned to better legs after a fall, the wheels had rust in depth and the engine did not start. That being said I decided to proceed with its restoration which began in spring 2002. Before you start I'm concerned to have the Operating / Maintenance required for the proper setup and wiring diagram, workshop manual, which is essential for the process of overhauling the engine and spare parts catalog from which you can find any particular position at the exact replacement, bolts included. However, the restoration of a Diva does not require special expertise in fact, it is built in traditional style, but as the degree of difficulty we can add somewhere between the simplicity of a Vespa and the extraordinary complication of Lambretta. We now list
damaged parts found:
The seat cover had broken at the projections of the casing, has been faithfully reconstructed by a skilled artisan in Brianza to 120 Euro.
The pivot front suspension very loose due to insufficient maintenance / lubrication has been replaced with an original found at 15 Euro (probably equal to any model for sale at the time).
The ring of the lighthouse, as I said, eight had cracks on the back: I could not find a replacement and I had to engage in a painstaking argentame welding and polishing. The glass of the lantern was the type to be 105 instead of 110 CEV Aprilia, this measure (IGM0143PM) is unusually difficult to find today, do not tell you how many I rummaged through boxes at flea markets. But a stroke of luck ... has resulted in a vintage car spare parts dealer in my town had one, because there was never asked by anyone, 5 Euro.
Glass odometer was ruined, being a normal sleep I replaced with an equal for Lambretta LD (4 euros). The rubber on the pedal starter on the brakes, the bellows on the intake duct and the tripod shoes were missing, these items are still supplied by the air and can be purchased through the normal sales network, the prices are proportional to the availability of parts. Both shocks were ineffective, so it is audit work was done with replacement of rubber seals and reconstruction of the bushings loose.
The two caps limit the oscillation of the engine were damaged, probably because of long contact with oil and gasoline, I replaced them adapting and shaping other commercial production. The two brass bushings on the shaft oscillating engine was worn out due to lack of lubrication, before I made them build a turner but then I adapted a pair of silent-blok (20x40x32) to improve the mechanical isolation with the chassis.
The platforms are attached to the frame with the interposition of anti-vibration rubber washers to replace them fit well the same as mounting the Lambretta LI.
The plastic tail light was fading and needed replacing, but I brightened up her seat inside surface of transparent red spray a particular color used for decoration of glass. The result was very satisfactory. However, the original plastic Aprilia is not difficult to find in markets.
seal instead of the tail light was replaced with original parts, $ 10.
engine, quite conventional, did not require a particular work unless the polishing of the cylinder and replacement of piston rings. I had a little 'difficulty instead of replacing para oils, some measuring no longer in production: the right side of the tree engine is the width of 10mm while the market I found only 7 mm spacer I made up the difference. Even for pour oil output spindle of goodwill must arrangiasi making adaptations. The clutch plates were replaced and are the same dell'Isoscooter. I noticed, a certain failure of the springs that I did not push hard in any case be replaced. Recommended by an old mechanic, instead of pulling to stretch groped, I retrieved hammer on the sides in transverse direction. For information to be extracted with the flywheel puller (the measure 27P.1, 25) which is the same for the Lambretta LI. The unpainted parts and small parts are all treated galvanically. In particular, the bolts are chromed levers of control, the ring of the lighthouse, the light dimmer switch cover and two screws, the frame and locks the odometer. The nuts and bolts, a tripod, the shock front, the clutch lever, the kickstarter and rear brake levers on the drums and various media are all galvanized. The aluminum parts are simply polished. The body is most common in the combination two-tone ivory / blue. The blue for the covers and front bezel, ivory on the rest of the body including the fairing of the handlebars, rims, hubs, frame and plate holder. In the black cap ventilation, rear fender, the battery holder and the suction box. The fuel tank is rust matte gray, and gray are the aluminum seat frame including the latching plate rear shock. The muffler (Lamfranconi IGM0345S) is in matt black high temperature. In the blue box of the rectifier.
The assembly is not complicated and I have learned that the engine must be installed before the tank would not pass. It so happened that in the summer of 2002, the scooter was completed, I can only start it. It was great curiosity to hear her roar and be able to ride. I took her out of the garage / workshop, open the fuel tap, closed the air and scalciai. First hit anything, not even the second, but I received a strange rebound, went to third. The engine ran at once cheerful and adjust the throttle felt good, because regolai now roughly the minimum speed was increasing dangerously. Its not really a diamond, it reminded me mostly my Vespa 50 when I was a kid.
I tried to climb over and immediately put the first few meters after the second and vigorously, and then accelerated in the third. I saw my son wanted to go back now ... and into the countryside. From the outset it became evident the need to care for the adjustment of the cables that were inaccurate and controls the brake in the drive is in the clutches of gears.
The engine has a strong couple, but a top speed of 80kmh without hesitation, even if it vibrates a bit at high speeds'. The position of the pedal starter is not really happy and the proximity to the platform requires a non-optimal support with the foot. The control of air and gasoline are not easy to reach, probably did well in the first version that was equipped with the solo seat. The front brake is safe even if the suspension sinks like the Vespa, while the rear lock easily and needs a little 'practice. He has a strange behavior when entering a curve as if unwilling to bend, I had to tilt the steering seems to be incorrect. Well in advance
began the practice of re-registration, knowing the time, and in September I passed the acceptance test the MC, after six months, but has not completely ended, I still lack the ownership certificate from the PRA.
In the meantime I tried to purchase accessories for this scooter aesthetically enriching, at the time he built several Viganò, but are now hard to find. However, a former motorcycle spare parts I found some Modena. With your permission I report his address because of the material have mainly spare parts for the engine: Mr. Giancarlo 335290477. Now it is already working and uses it mainly for my wife who prefers his commands shift knob than dell'Isoscooter foot.
with ISO F/150 I made some out and I like to mingle among the Vespa and Lambretta their rallies to arouse their curiosity and questions.
Most people said it had never seen, but with pleasure there is always someone who remembers having noted in his youth.
