OUR METODOLOGY

Restoring a motorcycle requires, in all cases, a careful and involved process, until the final result is reached, with total respect to the original specification .In our opinion, implies to follow a number of steps that we apply as follows:

 

1.  EVALUATION OF THE GENERAL CONDITION

It is essential to perform an examination of all the parts of the motorcycle, checking for wear, condition , originality, and whether they are correct for that model and year of manufacture.

This allows us to do an  estimate of the time and parts needed to complete the work.To this end, we perform a detailed study of the motorcycle, that  we compare  against our ample documentation on the HD  make

At the same time we perform a photo or drawing  study of every part and detail, that will continue when we start the dismantling. We record, step by step, any action , so that later, if necessary we have these photos and drawings  as reference, an also to facilitate the comparison with the original  parts catalogue

 

2.  FINDING AND BUYING PARTS

 

 Once the motorcycle  is dismantled, we locate , through our ample network of suppliers, all the parts needed. We try to do this early to avoid delays , later, due to some parts being difficult to obtain.

 

3.  CHASSIS AND BODYWORK

 

Once the dismantling is complete, our priority is  to rectify all chassis structural parts, suspension fork  etc, putting right any faults, and doing all work, like welding etc to restore to exact original condition. In occasions, this means substitution of the part. In all cases, after this work we perform checks to ensure correct alignment of everything.
Once we  are satisfied, the chassis is sandblasted and primed with special paints. In the bodywork, all parts , like fuel tank, toolbox , battery box etc, we try to recover everything . If the part is deteriorated beyond recovery, we try to  find a  second hand part, or an exact copy is made.

4.  WHEELS

 

 In all cases ,we use new stainless steel spokes, in the correct original sizes and we use tyres exact replica of the originals, and  apply the correct finishes to the rims, etc,  as per the original model.
In models with brakes with internal shoes, we check both drums and backplates, on the lathe , to correct  possible imperfections. In older models, with external shoes, we recommend the owners to fit thicker drums, to avoid possible deformations and the resulting deficient braking.

5.  LATHE WORK

 

This is often overlooked, but we like to give special importance to this chapter. All the phases of the restoration are important, but we understand  it is essential to put 100% right any play between parts, due , may be , to wear and prolonged use.
At times, even new parts show problems, that need to be corrected. If this is not done, the result is , in all cases, failures, poor performance, deficient braking, etc. That is, a poor final result.

 

6.  MECHANICAL PART

 

When dealing with this chapter ‚Äďengine, gearbox, carburettor, we put special attention to improving the general performance and in avoiding leaks and drips. In all cases, the inner surfaces of the engine and gearbox cases, are treated with special resins, to cure the frequent problem of oil ‚Äúsweat‚ÄĚ trough the pores of the cast aluminium.
In all engines the head is checked , and planed if needed, crankshaft, conrods, pistons, valves , valve guides and all parts are checked and rectified, and when not possible, replaced. Same is done to crankshaft, all pinions and oil pump.
Same is done to electrical parts, like dynamo or magneto. We insert new, modern, more efficient  seals , and sealants ,to get the best possible oil tightness of both , engine and gearbox. All sealing rings in the  inlet tube to the carburettor are replaced.
The carburettor is rebuilt in the same manner, putting new parts as needed..
Cylinder cooling fins are rebuilt when needed,  to regain efficiency and aesthetical appearance. Al crankshaft bearings are checked or replaced, and all nuts and bolts replaced with exact copies of the originals
Gearbox.

In all cases, we use modern sealed bearings in place of the needle types.

An sealing ring is inserted in the left side of the gearbox axle, as well as to the starter pedal axle. The adjustable bearing on the output shaft is replaced. All gears inside the box are checked and rectified as needed. Same is done to the clutch parts, replacing as needed

In older models, the output shaft is replaced with a more recent type, to eliminate the need for half bearings, as in later models

All nuts and bolts renewed/ replaced with exact copies of original. Exterior finish is as per original specification

Carburettor:

We substitute the cork buoy with one made of copper, for better adjustment and check/rectify as necessary the throttle shaft, needle and its seat, etc.
All play in the carb parts is adjusted and eliminated

 

7.  PREASSEMBLY

 

If the vehicle comes to us completely assembled, we do a check of all parts and elements for condition. If it comes partial or totally dismantled, then we prefer to do a reassembly  and perform the check, avoiding problems at later phases.

This is particularly important when the bike  or part comes partly restored. This way, if some  parts are already restored. like chromed or painted, we avoid problems at the time of final assembly, and the resultant loss of time and money.

 

8.  PAINT & FINISH

This is the most visible part of the restoration.  If it is less than perfect, then it detracts from the general results, and the other pats of the work will be less appreciated.

The paint is always done in a professional workshop, and includes a minimum of two layers of paint and two of lacquer, for a perfect finish.
All colours are as per original specification.
Nickel and chrome finishes ,according to models, are done with  a previous copper plating. We are particularly strict with the quality control of this process.

9.  FINAL ASSEMBLY

 

This is the most rewarding part of the whole process, when all the problems found are left behind, and is the time for the final assembly. We put special care in avoiding any marks in paint or chrome. As one example, all nuts and bolts are protected with masking tape, to keep the finish perfect.

 

10.  TEST AND TUNE-UP

 

It is now the time to see that all work done was correct, and no aspect was overlooked.
We need to  check all parts  for correct functioning, no oil or fuel leaks, all controls working correct and smoothly , and  engine , gearbox, brakes etc, working without defects .To this end we always perform a road test of a minimum of 100 Km, to ensure the correct functioning of everything.

All along the resto, we keep a photo record of all work done, that we handle to the owner at the end.
