Checking the engine oil level
Check the engine oil level through the sight glass (1) on the right-hand side of the oil sump.
Stop the engine and allow a few minutes for the oil to settle to a steady level. Check the level with the motorcycle perfectly vertical and with the engine warm (but not running).
The oil must be between the MIN and MAX marks. If the level is low, top it up.
Remove the filler cap (2) and top up with the recommended oil.
Refit the cap (2).
If the level is below the bottom mark, top up with SHELL Advance Ultra 4 engine oil.
Changing the engine oil and filter cartridge
 Notes
Change the oil when the engine is hot (but with the engine stopped). In these conditions the oil is more fluid and will drain more rapidly and completely.
 
Remove the drain plug (3) with gasket (A) from the oil sump and allow the oil to drain off.
 Warning
Dispose of oil and/or filter cartridges in compliance with environmental protection regulations.
 
Remove any metallic deposits from the end of the magnetic drain plug (3). Refit the drain plug complete with gasket (A) to the sump.
Tighten to the specified torque (Sect. C 3, Engine torque settings).
Remove the oil sump filter cartridge (4) using service tool 88713.2906.
 Important
Dispose of the used cartridge, do not attempt to reutilise it.
 
Fit a new cartridge (4) using service tool 88713.2906: lubricate the seal with engine oil.
 Notes
It is advisable to fill the filter cartridge (4) with engine oil before installing it: this enables the recommended oil level to be maintained without topping up.
 
Screw the filter into place and tighten to the specified torque (Sect. C 3, Engine torque settings), using service tool 88713.2906.
Every two oil changes, clean the oil pickup gauze filter.
Remove the horizontal cylinder exhaust pipe (B) by unscrewing nuts (C) and clamp (D).
Unscrew the outer plug (6) with the seal (5).
Unscrew the filter (7) and withdraw it from the crankcase.
Clean the filter with petrol and compressed air. Take care not to damage the gauze.
Replace the pick-up filter (7), fit the seal (5) to the plug (6) and tighten to the specified torque (Sect. C 3, Engine torque settings).
Remove the filler cap (2) and fill with oil of the recommended type (Sect. C 2, Fuel, lubricants and other fluids) up to the MAX line in the sight glass.
Refit the filler cap (2). Run the engine at idle speed for a few minutes.
Check for oil leaks. Check that the oil pressure light on the instrument panel switches off a few seconds after the engine starts. If not, switch off the engine and trace the fault.
After a few minutes, check the oil level again and top up to the MAX level line, if necessary.
Refit all parts removed.
Checking valve clearances
In order to check the valve clearances, it is necessary to gain access to the four valve covers on the cylinder heads and then remove the parts listed below.
 
Remove the inspection cover on the alternator side of the crankcase, insert the handle of service tool 88713.0123 in the holes of the alternator-side crankcase cover in order to rotate the crankshaft to bring the valve being checked to its rest position.
With the valve in the rest position, slide a feeler gauge between the opening rocker and the opening shim to measure the clearance.
The clearances must be within the specified limits:
 
With the valve in the rest position, slide a feeler gauge between the closing rocker arm and the closing shim to measure the clearance:
 
If the measured clearances are outside the prescribed limits, replace the opening and/or closing shim, as described in the paragraph “Removal of the rocker arms, shims and valves” (Sect. N 4.4), with one of suitable height to obtain the specified clearance.
 Notes
Replacement opening shims are available in sizes ranging from 1.8 to 3.45 mm, while closing shims are available in sizes from 2.2 to 4.5. Each shim is marked with its size.
 
Refit all the removed parts in the reverse order to that in which they were removed.
Changing and cleaning the air filters
The air filter must be renewed at the intervals indicated in the “Routine maintenance table” (Sect. D 3).
 
Unscrew the bolts (4) and remove the pad (5).
Unscrew the six bolts (1) securing the airbox cover (2).
Remove the cover (2).
Remove the filter cartridge (3).
The filter cartridge can be cleaned with a jet of compressed air or renewed as necessary.
 Important
A clogged air filter will reduce air intake and engine power, increase fuel consumption and cause a build up of deposits on the spark plugs. Do not run the engine without the air filter. This would draw foreign material present in the air into the engine and could damage the engine.
Install the cartridge (3) in its housing (A) in the airbox cover and replace all the removed parts; tighten the bolts (1) to the specified torque (Sect. C 3, Frame torque settings): in the sequence 1-2-3-4-5-6.
 Important
If the motorcycle is used in very damp or dusty conditions, the air filter cartridge must be changed more frequently.

Tighten the locknut (7) and recheck the pedal freeplay.
Adjusting the rear shock absorber
The shock absorber has external adjusters that enable you to adjust the suspension to suit the load on the motorcycle.
The adjuster (1) located on the right-hand side, where the lower end of the shock absorber is attached to the swingarm, controls rebound damping.
Turn the adjuster (1) clockwise to stiffen the damping H and anti-clockwise to soften it S.
Adjuster nuts (2) and (3), located at the top end of the shock absorber, serve to adjust the preload of the outer spring.
To adjust the spring preload, unscrew the upper adjuster nut (3) using a pin wrench. Screw the adjuster nut (3) in or out to respectively increase or reduce the pre-load.
STANDARD setting from the fully closed position (clockwise):
-
unscrew the adjuster (1) by 12±2 clicks (rebound adjustment);
-
 Warning
To turn the preload adjuster nuts, use only a specific tool and take care, otherwise the wrench pins may slip off the nut. This could injure your hands. Never use a wrench with a too small pin or with a too short handle.
Standard length of the preloaded spring on the shock absorber with the rear wheel raised off the ground: 166±1.5 mm.
 Warning
The shock absorber is filled with high-pressure gas and can cause injuries if inexpertly dismantled.
 Important
If the motorcycle is to be ridden with a pillion rider and luggage, we recommend setting the rear shock absorber spring preload to the maximum to ensure the best handling and proper ground clearance at all times. It may also be necessary to adjust the rebound damping accordingly.
