This is my XS650B from 1975. The list of what I’ve done is long. I changed to the correct fuel tank (bought a used one from UK, imported from the USA). I stripped all paint and painted everything using a spray gun (mending the tank – big dent) using lead filler. I sent the OEM exhaust pipes for a re-chrome, new saddle cover, front mudguard, tail lamp (Lucas copy), mufflers etc. The engine was renovated with lots of new stuff (new pistons, valves etc.) but most importantly the crank was rebuilt by XS-shop in Germany.

We fabricated new front mudguard stays to mimic an old British bike. Many small parts were re-plated (zinc-nickel) using a Caswell kit in my workshop. Wheels rebuilt by me with new aluminium rims (18-inch both) and stainless spokes. Clocks came from a jumble, fitted to a home-made console with idiot lights. A new main master cylinder (with smaller piston) for the disc brakes improved it a lot! I also made sure it had new bearings and seals in both wheels, new tapered steering head bearings and recommissioned bushings and new seals in the swingarm. Oh, and a new wiring loom, progressive fork springs and bespoke NJB rear shocks. Controls are from a TR1, brake pump from an XZ550.

Hardest thing to do: fitting the decals on the tank before the lacquer coat!
