Break-In; Maximum Throttle Opening Recommendations; Breaking In The New Tires - HYOSUNG GV 250 EFI Owner's Manual

BREAK-IN

The opening explains how important
proper break-in is to achieve maximum life
and performance from your new Hyosung.
The following guidelines explain proper
break-in procedures.
★ ★ MAXIMUM THROTTLE OPENING
RECOMMENDATIONS
The table below shows the maximum
throttle opening recommendation during the
break-in period.
Initial 800 km (500 miles)
Up to 1,600 km (1,000 miles)
★ ★ AVOID CONSTANT LOW SPEED
Operating the engine at constant low
speed(light load) can cause parts to glaze
and not seat in. Allow the engine to
accelerate freely through the gears, without
exceeding the recommended maximum
limits. Do not, however, use full throttle for
the first 1,600 km (1,000 miles).
★ ★ VARY THE ENGINE SPEED
The engine speed should be varied and
not held at a constant speed.
This allows the parts to be "loaded" with
pressure and then unloaded, allowing the
parts to cool.
This aids the mating process of the parts.
It is essential that some stress be placed on
the engine components during break-in to
ensure this mating process.
Do not, though, apply excessive load on
the engine.
Less than 1/2 throttle
Less than 3/4 throttle
34
★ ★ BREAKING IN THE NEW TIRES
New tires need proper break-in to assure
maximum p e r f o r m a n c e , just as the
engine does.
Wear in the tread surface by gradually
increasing your cornering lean angles
over the first 160 km (100 miles) before
attempting maximum performance. Avoid
hard acceleration, hard cornering, and hard
braking for the first 160 km (100 miles).
WARNING
Failure to perform break-in of the tires
could cause tire slip and loss of control.
Use extra care when riding on new tire.
Perform proper break-in of the tire as
described in this section and avoid hard
acceleration, hard cornering, and hard
braking for the first 160 km (100 miles).
★ ★ ALLOW THE ENGINE OIL TO
CIRCULATE BEFORE RIDING
Allow sufficient idling time after warm
or cold engine start up before applying
load or revving the engine. This allows
time for the lubricating oil to reach all
critical engine components.
★ ★ OBSERVE YOUR FIRST, AND
MOST 1,000 km SERVICE
The 1,000 km (600 miles) service is the
most important service your motorcycle
will receive.
During break-in procedures, all of the
engine components will have worn in
and all of the other parts will have seated
in.
All adjustments will be restored, all
fasteners will be tightened, and the dirty
engine oil and engine oil filter will be
replaced.
