HONDA CB750 FOUR PART 6 – the start of the final build

Things starting to come together. Engine in, front end on, oil tank in, battery in, shocks mounted, and swinging arm in.Forward view of the construction. Wiring and exhausts are left for later.

Finally I have reached the stage of reconstruction. The frame has returned from the painters (‘Full Range Finishes’ – Letchworth) and the swinging arm freshly chrome plated (‘Doug Heath’ – Baldock). Firstly the frame was prepared with new head races and all the threads cleaned. The engine was placed on the bench on its side. The frame was then lifted over the engine. This is the easiest method of putting the engine in the frame without giving yourself a hernia. Items like the alternator, oil pump, clutch, oil filter and sump pan can be put on later. Anything to keep the weight down for insertion into the frame. Once in the frame, all the above parts were fitted.

I then put the front end back in complete, as I had already finished and assembled it. The oil tank was then fitted and the hoses to the engine and the oil cooler were also put into place. The modified ‘Dresda’ swinging arm was fitted with the ‘Hagon Nitro’ shocks. The custom battery box and battery were mounted. The 31mm CR special carburettors are mounted and connected to the throttle linkages. I then placed all the electrical  components into place; the micro digital box, single phase regulator and micro coils. The rear sets were then fitted to the rear frame hangers.

Next time I will talk about the wiring and some of the teething problems I have encounted. Until next time, wishing you all a happy new years motorcycling.
