G'Day Scouser,
you are looking at a swingarm FX-FL type frame, 4 speed with an evo Motor. Produced between 84 and 87. 1987 was the last year and only FXWG's were made that year. In 86 the FX label went to the FXR frame with 5 speed Tranny's. The bike on the Photo has fournales shocks after market horseshoe oil tank custom forward controls and Disc glide rear wheel and custom front.
Hope this helps.
Cheers,
Cris.

 That bike looks familiar. Was it featured in Ozbike many moons ago ?
