Well, over the last few weeks I've collected loads of bits (mainly Ebay). So I've settled on a BSA Firebird export tank (the starfire was too small) and am now in the process of modifying the frame to fit the tank, GS 1000 forks and yokes, GS 550 swinging arm, Starfire sidepanels, A65 humped seat, alloy mudguards, A65 rear light.......enough to keep me occupied for a few weeks.
