This is a brand new project i just acquired. At this point i do not have a solid plan but i am beginning to think Dover White. This bike was acquired in “baskets”, so to speak and will require a full and complete restoration.
As you can see i decided on Dover White and have been making decent progress. The engine has been completely re-done including a totally rebuilt crankshaft. The engine was bored 2nd over and fitted with new pistons. The heads received new Black Diamond Valves, guides and seats and all work done by North East Machine. The reassembled engine received the proper rear spherical bearing along with all new bearing as seals. Engine, transmission and final drive cases were media blasted and coated with Eastwood Hi-Temp Clear satin to prevent oxidation. The transmission and final drive also received a total rebuild with new bearings and seals. The frame and swing arms were blasted to bare metal and a zinc primer applied and baked the surface was scuffed and then painted. All of the polishing and chroming was done by Niagara Plating.
the 1955 and 1956 R69 bikes had some very unique features that were eliminated in the later R69 models such as the “dished” head light bucket, the rounded front shock covers and the small ridged mounted head light ears. One of the most unique items were the very rare “single cross” spoke pattern in the wheels and hubs. in 1957 they went with the traditional 2X spoke pattern. The wheels, (not shown) are the single cross type with polished early Weinmann aluminum rims. The wheel hubs were stripped and media blasted and fitted with new wheel bearings that were properly preloaded, laced onto single cross newly polished rims and trued. Heidenau 350 X 18 tires and new tubes were mounted to give the early tread pattern look and feel on the road.
