It was an 850 and it had my prototype lightweight custom pistons from Wiseco which enabled it to stay together (solid frame). I had to shorten the cylinders for the shorter pistons. The cases were reinforced because I had them crack earlier on with heavier Hepolite pistons. I didn't have the BSA lifters together then but borrowed an Axtell cam from Ken Canaga and lightened the stock lifters to the max (Revved it to valve float with racing valves). Axtell porting copies thanks to Ken Canaga loaning me a head. With the torque of the 850 I noticed my gears wearing on an angle because the shafts were flexing so I adapted an outrigger bearing. I installed a close ratio 4 speed but was hurting bad for a 5 speed (I was broke). The frame was inspired and taken off the dimensions of the Ducati TT2. I made the 1st non metallic fork bushings and adapted damper cartridges from Marzocchi rear shocks.

The Ducati TT2 (F1)s were far superior. Stock they were just as fast as my tricked out Norton. I just couldn't afford one. So I pushed myself harder through the turns and eventually learned to feel it start to slide and held it there. But when the watercooled 851 Ducs came out it was all over for privateer innovators like myself.
