1970 Triumph Bonneville. $13,000 OBO. Completely rebuilt. Every bearing replaced in the entire bike and most bushings as well, new fork tubes, spokes, rims, and tires, professionally painted and hand pinstriped. Rebuilt speedo and tach. All new wiring. Tri-Spark ignition and MOSFET regulator. New exhaust. New seat. In short, this is basically a new bike. See the writeup and pictures of it being built here and it's advertised here.

1969 Norton "S". This bike's story is a weird one. In early 2021 a guy contacted me wanting a drum brake Roadster. I had no drum brake bikes. So, he asked if he found on could he ship it to me to check/fix. A few months went by and he found what he thought he wanted in the Northeast. He bought it and had it shipped directly to me. As it was supposedly a running/riding bike, I gave it a quick once and took it for a short ride to see what worked and what didn't. It ran find and shifted fine. So I stated inspecting but noticed the smell of burning wires – sure glad I was right there, the wires caught fire! OK, that's one thing wrong! Then I started writing down what was non-standard. After a bit I realize that this “Roadster” was really a 69S. Also, the taillight was pointing down at about a 30-degree angle. That turned out to be what I call droopy butt. The rear loop was bent down – I've fixed that. The bike don't have the 69S special parts and was being converted more or less into a Roadster. Once I told the owner all this, he was up in the air whether to make it into a Roadster or 69S. He finally decided on 69S but soon after I started, he found a proper Roadster and wanted to be rid of this bike. He over-paid for this on. I bought is and he took a nice big loss. If you want to build a 69S you'll need the special 69S parts, but it will be fairly easy to get there. If I ever get to it (about eight bikes ahead of it) I figure, I'll have $11k in it when done. I'm happen enough to just sell it – I greatly prefer 1972-1974 Nortons. I have $6400 in it – make me an offer!

Coming Soon


1974 Triumph Trident.  When parked it was running fine but needed a new clutch bearing.  Turns out that the clutch plate had uneven wear from the previous owner not properly assembling the clutch. That has been corrected and the clutch pulls easy and works well.  Also, the sprockets were just OK - since it was apart I installed new sprockets and a new chain.  The tank is nice and painted in the correct 1974 colors, but the pin stripes we not hand done so they look too good.  I may treat this one to a new set of Amal Premier Aluminum carbs.  It will have an Tri-Spark ignition and MOSFET regulator and a new wiring harness.  It will be a well-sorted rider and I'm guessing it will sell in the $9000 range. The Trident has been on a back burner as I had three Nortons to build for customers. One was a basket case the owner brought me to build and it has been delivered.  The other two are for another customer.  Those two are almost done. Look here

Recently Sold


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 beautful and painted correctly for a 73 Trident.  It is a well well-sorted rider I sold for under market to an Acess Norton member.

1974 Norton Commando Roadster. $13,000. 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.  See the writeup and pictures of it being built and upgraded here.
