Cycle Parts 

Tanks

The tank on the '72 GT is made of fibreglass, there were two types.
tankearly tanklate
This early tank has a section between the top of the tank and the profile of the knee pad cut outs differs to the later type. This later tank has a knee cut out much closer to the top of the tank as well as a narrower scallop.Decal position is too high.

Fuel Taps and Caps

Top row features the left side tap, bottom row the right side tap. Click on the images for a close up. Fuel tap lever is turned to the front for fuel off, vertical for fuel on and rearwards for reserve. The taps are marked " C " for the closed position and " R " for reserve. Clips are original.
Replacement seals are available in Viton, a vast improvement on the originals. A gentle hand is required when dismantling, the threads on the hex are alloy and easily cross threaded.The taps are the same on all the 750GT year models.


 Gran Tourismo, made in Italy by G.Narva. This is an original piece of hose, rare to see now.
The fuel cap seal on the '72 model is of the large diameter, later models also had a smaller seal. Viton replacement seals in both types are available.

Seats

Two different seats were also supplied on the '72 models, the lower flatter seat was also fitted to the later GTs up until 1974. A third variation on the theme is the flat low style seat but without the lower seat trim made of aluminium.

The flat seat with no trim is from a factory image, of an earlier bike than the two others depicted here.
As far as I know, the '72 models didn't come with a knob to secure the seat at the rear, they were fitted with a screw. Of course the tool kit was under the seat, but a 5 cent piece will do the trick. Most owners fitted seat knobs from the '73 and later models, both are pictured below.

 


Sidecovers

1972 was the last year for fibreglass on the GT750. For 1973 both tanks and sidecovers were steel. The shape of the early sidecovers with the metalflake finish added to what we now call the retro look.
Constructed of fibreglass mat the sidecovers are strong, surrounded by an extruded plastic moulding. The molding has a welded join. The mesh for the grille is of expanded aluminium and as you see, simply glued into place. A 6mm chromed, slotted screw with a rubber washer secures the sidcover in place. These washers help to protect both the sidecover and the molding. Mine aren't original, being punched from a reinforced 2mm sheet.

Guards Front and Rear

Both the front and rear guards on the '72 750GT are stainless steel and marked " Inox ". I have seen these guards without the Inox stamp, though all have been sourced as spare parts, so I can't confirm whether any without the mark were fitted as original equipment. Early '72 models had no brace across the fork legs, my late '72 has a brace.

The front guard " INOX " stamping. The feet belong to a bibendum decal.

Quite often these tabs to hold the wiring under the rear guard will be missing, there are four in total. If they're not missing on your bike, protect them with a galvanising paint.


Chainguard

The chainguard is stainless steel, the mounting brackets are spot welded. All GTs from 1972 had the same chainguard.


Handlebar Controls

A low and narrow handlebar was fitted to the bikes for the European and Australian markets.
Quality controls were fitted - Verlicchi grips, Tommaselli Daytona 2C throttle but no mirrors. You can make your own arrangements there. Personally I prefer the alloy bilet CRG Hindsight mirrors, but good old bar ends were and still are far more popular.

The left side controls for the clutch were robust and the choke lever was atop the pivot perch. The clutch perch is secured with an 8mm socket cap screw, not too tight ! The Aprilia switchgear was held with two roundhead slotted screws to the front of the perch. Preload tension on the choke lever is adjustable by way of its mounting screw and locknut.

 The steering damper is a friction device adjusted by a plain bakelite knob in the centre of the upper triple tree steering stem tube. The friction washers and plates are held under the lower triple tree.

Headlamp and Blinker Supports

The stylish headlamp and blinker supports were a feature not seen on other makes. Certainly different and effective. However, the rear blinker support wires tend to fracture at the mounting weld which given the weight of the blinker and stalk they're supporting shouldn't come as a surprise.

In 1972 the headlamp wire support was different to the later years by virtue of an elongated hole for the front blinker mount. The headlamp support mounting had a nylon washer either side of the support wire. The machined outer washer washer and mounting bolt were either zinc plate or chromed.
The rear blinker stalk , nuts and shakeproof washers were cadmium or zinc plated.

Tail Lamp Brackets

There were two types of bracket made by CEV, matched to the early and later tail lamps. Below are pictured the early, late rear view and later side view.

Yes, the lamp sloped downwards.
The lamp is level on the later style.
