Harley-Davidson 1927 Model J 989cc 2cyl IOE V-twin 3312



Harley-Davidson 1927 Model “J” 989cc IOE V-twin engine # 27J7183

From 1915, after a number of years of development, the top-of-the-range twin with full electrical equipment is listed as the Model J. For many enthusiasts the modern Harley-Davidson motorcycle truly comes into its own in 1925 when the entire range is fitted with new frames that lower the riding position by a full three inches, allowing smaller riders to handle the bikes with greater ease. The wheels become smaller in diameter and the petrol tank gets a more dynamic teardrop shape. All in all these new models look much more modern than their predecessors. In the 1926 model year wider mudguards and a revised exhaust system are introduced, together with a higher dynamo output and battery capacity. For 1927 no more than 3561 model J 1000cc machines are sold; the 1200cc JD is much more in demand with 9691 units leaving the factory. Not surprisingly perhaps, as the price difference between these models is a mere $10. 1927 is the first year of the “wasted spark” distributorless ignition system using a circuit breaker and a single coil firing both spark plugs at once. The J engine delivers 18 hp@3400rpm, good for a top speed of almost 110 km. The rear brake is an external contracting band that is controlled via a pedal near the right footboard.

This “J” has a charming patina and has been sympathetically restored, though some recommissioning will be required.
