EXCESSIVE OIL CONSUMPTION
Excessive oil consumption may be due to:
Badly worn, or stuck up, piston rings. (Causing high pressure in the crankcase).
Worn valve stems.
EXCESSIVE PETROL CONSUMPTION
Excessive petrol consumption may be due to:
Leaks in the petrol feed system. (Damaged fibre washers, loose union nuts on piping,
defective float needle action).
Incorrect ignition setting. (Ignition not advanced sufficiently).
Defective engine valve action.
Incorrect use of air control lever.
Moving parts of carburetter badly worn. (Only possible after very considerable mileage).
Bad air leak at carburetter junction.
STEERING UNSATISFACTORY
Incorrect steering head adjustment (too tight or excessively slack).
Pitted steering head ball races resulting from loose adjustment.
Wheels out of alignment.
Front and/or rear tyre tread not correctly manipulated to run true with wheel (causes
handlebar oscillation at low road speed).
Damaged front fork main tubes resulting from impact.
ABNORMAL TYRE WEAR
Abnormal tyre wear may be due to:
Incorrect tyre pressure.
Wheels not in alignment.
Harsh driving methods. (Misuse of acceleration and braking).
CLEANING THE MACHINE
Do not attempt to rub, or brush, mud off the enamelled surfaces because this will soon
destroy the sheen of the enamel. Mud, and other road dirt, should be soaked off with
water.
The best method is to use a small hose, taking care not to direct water on to the engine,
carburetter, magneto and other such parts. As a poorer substitute, a pail of water and
a sponge may be used.
After washing down with water, the surplus moisture should be removed with a chamois
leather, and, when the enamelled surfaces are thoroughly dry, they may be polished
with a good wax polish and soft dusters.
Such parts as the engine crankcase and the gear-box can be cleaned by applying paraffin
with a stiff brush, and, with a final application of petrol, will come up like new.
CHROMIUM PLATING
Under some climatic conditions, a rusty looking deposit may be observed on ferrous
parts that are chromium plated. This is not ordinary rust (ferric oxide) but is a salt
deposit that, in most cases and in its early stages, can be quickly and easily removed with a
damp chamois leather. In stubborn cases, it may be necessary to use a special chromium
cleaning compound.
The safest precaution during winter is to wipe over all chromium plated parts with a
soft rag soaked in "TEKALL", which is a lanoline base rust preventative marketed in
small tins and available at most garages. This material, so applied, leaves an almost
invisible film that is impervious to moisture and its use cannot be too highly recom-
mended to owners who value the appearance of their mounts.
In summer, when those conditions do not prevail, chromium parts should be frequently
cleaned with a damp chamois leather and afterwards polished with a soft duster.
If a polish is used it must be one of the special compounds for chromium plating only.
Ordinary metal polishing liquids, in particular, must not, on any account, be used because
these, almost without exception, contain acids, which attack chromium,
