1973 Triumph Trident. This bike was running great when I bought it in PA and needed some TLC to be a good rider - that was about 3 years ago. I've finally got around to finishing it. The front end is rebuilt, the disc turned, the caliper and master cylinder rebuilt, new front tire (rear was new when I got it). The side panels professionally repaired and painted. The exhaust header is new, the pipes are original but in decent shape. Both mufflers are OEM Triumph. The right side it used but in good shape. The left side is NOS. The Tri-Spark ignition and MOSFET Voltage regulator are installed and I've made a new wiring harness. I had the OEM tank painted all black (painter couldn't do stripes). He was supposed to leak check/fix before painting. There was a pinhole that he didn't fix. I sent the tank to my current painter in CA and it is beautiful and painted correctly for a 73 Trident. It is a well-sorted rider I sold for under market to an Access Norton member.

1974 Norton Commando Roadster. Completely rebuilt. Every bearing replaced in the entire bike and most bushings as well, new fork tubes, spokes, rims, and tires, new tank and side panels (not India), new exhaust, professionally painted and hand pinstriped. Rebuilt speedo and tach. All new wiring. Tri-Spark ignition and MOSFET regulator. cNw breather and James Comstock exhaust ports replaced. In short, this is basically a new bike. After being sold, the buyer wanted it upgraded to a 520 chain and cNw e-start. He also wanted the red set of tank and side panels I had.
