A restoration is a long project with many small decisions. People who finish it have a plan and keep to it. People who do not finish it often start with enthusiasm, discover the cost of the first big job and lose heart. A plan does not remove the work. It tells you what you are signing up for.
1. Decide the goal
First, decide whether to restore at all: originality and patina. Then choose the target:
- A rider. Mechanically sound, safe and presentable. The cheapest and fastest.
- A faithful restoration. Correct parts, finishes and details for the model and year.
- A show-winner. The highest standard, with all the detail, at a high cost.
The goal controls the budget. Without it, the project grows by itself.
2. Assess before you start
- Check what is there and what is missing. Make a list of all missing and damaged parts.
- Find out which parts are available and which are not: see finding parts. A missing part that cannot be bought can change the whole project.
- Have the frame, forks and engine checked by someone who knows the make.
3. Build a budget
- Price the major jobs: engine rebuild, paint, chrome and plating, wheels and tyres, electrics, upholstery, brakes.
- Add the cost of small parts. Seals, gaskets, bearings, fasteners, cables and bulbs add up to more than most people expect.
- Add a contingency of at least a quarter. Old bikes hold surprises once they are in pieces.
- Compare the total with the value of a finished example. If the cost of restoring is far above the value, you need a different reason to do it than money.
4. Plan the order of work
- Document and photograph.
- Strip the bike, bag and label the parts.
- Assess the frame and have it repaired if needed. The frame is the foundation.
- Rebuild the engine and gearbox. Do this early because it often takes the longest.
- Send out the jobs that take longest: paint, chrome, plating, wheel building, upholstery.
- Rebuild the wheels, brakes and suspension.
- Do the electrics once the frame is painted, so you do not damage the finish.
- Reassemble, with new fasteners where needed, and keep the paint safe.
- Run in, test and adjust.
5. What to do yourself, and what not
- Usually yourself: dismantling, cleaning, documentation, basic mechanical work, reassembly.
- Often a specialist: engine machining (boring, crankshaft work), frame repair and alignment, paint, chrome and plating, wheel building, upholstery, anything that needs expensive tools.
Choose specialists by looking at their work and asking for references. Get a written quote, agree a timeline, and keep in touch while the work is done.
6. Keep a record
Keep all receipts, a dated log, and photographs from before, during and after. This record is part of the bike's value, and a future buyer will ask for it. See papers and proof of ownership.
7. Set a time limit
A restoration without a deadline drags on. Set a date, and a milestone for each stage. If you cannot meet it, adjust the plan, not your enthusiasm.
Check the rules before you finish
A restoration can change the status of the bike. In the UK, replacing the chassis, body, axles or engine counts as a substantial change that ends the MOT exemption: see the UK rules. In Germany, an H plate requires the bike to be largely original: see the German rules. In France the collection registration requires the original state: see the French rules.
