Update #5 - Fitting the Swingarm and Works Performance Shocks

I made and mounted two rubber discs to centrally locate and support the blind main bearing spacer that determines the swingarm's Timkin bearings preload. After machining up five aluminium spacers and modifying the steel axle shaft's threaded ends to fit, and checking preload for minimum play, all that's left to do is to grease the individual components and assemble the swingarm to the frame / engine combo.

The eye-catching Works Performance shocks that I have been saving for this project I have now mounted.

Update #6 - Trial Fit Campagnolo Magnesium Wheels and rare Spondon Rotors

The Patrick Godet Tribute bike build project being fitted with Campagnolo magnesium wheels and Spondon TZ250 rotors


At this stage I have been playing with various bits & pieces and have trial fit the exhaust, tach drive, and headlight, but mainly both the front and rear 18" Campagnolo magnesium wheels. The front wheel will require new sealed ball bearings to fit the 17mm Egli axle. I have also fit the Spondon TZ250 racing full floating rotors and magnesium carrier, but must now reduce the outer diameter of the rotors by 1/4" in order to mount the Spondon magnesium calipers with the proper clearance. The rear wheel also requires new bearings to fit the axle size. I'll need to order and install a 46-tooth alloy 520 racing sprocket and locate a suitable rotor, then machine up the axle spacers and design a hanger for the Brembo caliper. I'll also need to design a suitable torque arm, however, I now realize there is no swingarm anchor point for the torque arm. ...Hmmm...

So the rotors must now go off to the machine shop and both wheels to Connery's to be painted gold. I have also mocked up the rear sets and the new alloy plates that I made up. All looks OK so now I'll send the plates off to Chuck at Mayfair Plating in Toronto for polishing.

Update # 7 - Hooking up the Oil Feed & Return

I hooked up the oil feed line to the bottom right rear of the 4-inch tubular structural backbone on the Egli frame

I hooked up the oil feed line to the bottom right rear of the 4-inch tubular structural backbone that also forms the oil tank of the Egli frame. The chrome plated threaded-in extension contains a fine screen pre-engine filter and an automatic oil flow stop allowing one to temporarily unhook the oil feed line.

oil return line to its central position on the bottom of the oil tank

I have installed the oil return line to its central position on the bottom of the oil tank /backbone. The oil return line comes up the rear of the engine and crosses over the top. This line is hooked up to feed all four rocker arms, which are positioned behind each 'Vincent' inspection cap, supplying the oil while on its journey to the oil return fitting. As is evident in the photo this is a busy area with not only the oil return fitting protruding from the bottom of the tank but also the two Patrick Godet top cap breathers and fittings, along with the ignition wires, and with fuel lines yet to come. When the engine is running one can verify that the oil is returning by viewing the exit of the return line conveniently positioned inside the oil tank filler neck.

Update # 8 - Positioning the stunning Godet Racing TT Carburetors

We now go to the amazing 1 & 7/16 inch TT Carburetors that AMAL only produced for the Vincent racing efforts. These have not been available since 1953 so Patrick cast and machined his own! I have mocked up the carbs/float bowls in position, which is fairly complicated as it is paramount that they be installed in the optimum position for maximum horsepower. I must also provide clearances for everything and provide open area for the velocity stacks to maximize breathing. Nicely made stands with anti-vibration rubber mounts support the AMAL remote float bowls. The final fitting will require good positioning of supports and manifold angles and lengths.

front carburetor position determined by Patrick to fit the Lightening frame need to be adjusted for the Egli frame

The carb and manifold positions were determined by Patrick to fit the two Vincent frame components of his new Black Lightning project. However, on an Egli frame the round section of the 4-inch tube backbone crowds the front carb resulting in a slight outward lean to the left which I feel should be OK with the upright remote float bowl.

The left front down tube of the Egli frame's rear triangle section passes right through the position for the remote float bowl while also crowding the rear carb. I believe I can resolve these issues by shortening the rear manifold allowing the carb to pull in closer to the head and providing the velocity stack with additional open area for additional adequate air supply and also to reposition the rear float bowl mount to bring the bowl into proper proximity to the carburetor.
