Thanks for the pics, Dennis, However !! The # 786 Longtracker is Les Lewis' bike, powered originally by a TR, TD ? 350 road racing engine, now a 250, and built by Charlie Edwards. Nigel Boocock rode it at the Bendigo half mile in 1975 and won the meeting on it. Charlie and Nigel took it to England for the Grass-track meetings over there, the Poms promptly banned it !! The Bryant Special you refer to was there, Cliffy Patton rode the giant killing 125cc twin Longtracker in the races. The sound of Les' twin when he gave it some stick was delightful !! Great pics mate !! Les told me the gearing that he was running on the day was Morgan Mile gearing, a bit long for the 610 metre Fairbairn circuit !!!
Here's Booey and Charlie with the bike in it's original guise, carrying Charlie's #789 back in the '70s
And here's Doug Bryant, Wayne Bryant and KP with the 125 Twin at the meeting
