I starting riding Triumphs in 1968 and I've always done my own work.  Except for a year between when my first Triumph was stolen and I got another, I've always have a Triumph 500. While in college in the late 60s, it was my only transportation. During the 70s and early 80s, I rode a lot.  Then life got in the way for a long time and honestly, riding in the Washington DC area is not much fun - too much traffic.

I ride a little now, but mostly like to bring bikes back to life.  I prefer Triumphs, but lately have been doing more Nortons.  I like the power and lack of vibration of a Norton, but the handling of a non-oil in frame Triumph is superior in my opinion and I much prefer working on a Triumph engine.  2020 through 2022 have been almost exclusively Norton for me - I guess COVID-19 is why people kept bringing me their bikes to have work done. I did significant work on a 75 Commando and 79 Bonneville in 2020, but generally don't work on bikes newer than 1974.

May 2024:
  • A Trident that is in great shape but needed the clutch bearing changed, clutch plate changed, and the clutch tuned for perfect operation - that's done. I installed a Tri-Spark ignition and MOSFET regulator. It is in the process of being rewired. This was almost done when all the Nortons got in the way.  It just went back on a table to be finished. It too has never been restored but does have a repainted tank.
  • My 1967 T100C that I built as a 1969 T100R. It is being rebuilt again now. It was a basket case missing many parts and the only parts I could buy at the time were for a later bike so it transformed into a T100R with a later rear end. It originally had an Energy Transfer ignition. It's basically done but the a-hole I sent the tank and fenders to for painting in 2016 has not returned them.
  • Another 1967 T100C frame with title and a 1967 T100C engine that is close but not matching numbers. I'm planning on building this into a replica of the rare T100D. I already built one for a guy.
    See: 1970 T100R.
  • A 1971 T120R frame with title and a 1971 T120R bottom end.
  • The Rebuild from Hell, a 1967 TR6C being rebuilt as a 1969 T120. I've had a rear frame from a 1969 since I turned a T120 into a chopper for a guy in 1970. This bike was missing the rear frame so I'm using it.
  • A Trident that is ready to go at any time.  It has a pushrod tube leak, but is otherwise oil tight.  It has never been restored and has an original paint tank.  I've decided to keep this one and sell the one above.
  • A Trident that is apart in boxes.  The frame is repainted and ready but it will be a while before the rebuild continues.
    See: Back To Life.
  • A 1970 Bonneville that came as a part of a large lot of parts.  It's done and listed for sale.
    See: 1970 T120R Rebuild.
  • A titled, almost original 1969 TR25W
  • A titled 1968 T120R frame and a 1968 T120R engine.
  • A titled 1978 T140V frame and 1973 T140V engine. 
  • A 1969 T120R engine
  • A 1971 T120R engine
