Gas and oil tanks by The Cyclery

Item №
35-128

Nice reproductions of the fuel and oil tank combinations for 21” Singles 1925-1930 and the first 45” V-Twins of 1929. Made from soft soldered steel, with all stock brass bungs, brackets and fittings, just like the originals.

Gas tanks by The Cyclery for IOE models and early Flatheads from Harley-Davidson are still manufactured as they used to do it 100 years ago - most components, of which they are assembled, are soft soldered. This method worked back then and still works today, however, you cannot compare this technique with welding methods applied in the production of modern gas tanks.→

To avoid problems after finally bringing the gas tanks into service, the following points must be observed BEFORE painting and final installation:

  • Conduct a probationary installation of both tank halves and make sure that they rest stress-free on the frame. See the W&W selection of spacers and shims. Test fit petcocks and fuel/oil lines, too..
  • Fill all gas and oil compartments with gas. Ideally let the motorcycle sit for 2 seeks with all tanks full. Any potential leaks are reliably detected this way. If everything is in good order, remove and empty the tanks.
  • After drying, at least both fuel tank compartments should be coated inside with a suitable tank interior paint, which is also available from W&W. Pores and gaps inside are filled and the long-term tightness is significantly increased. In addition, it reliably protects against corrosion.
  • fits 21” Singles 1926-1930, 45” V-Twins early 1929
  • sheet steel
  • 11 l
  • required gas cap: screw-in 1.5”-24
  • required petcock: 1/8” NPT
  • replaces Harley-Davidson part number 3501-26, and 3502-26
  • gross weight: 14.5 kg
