2010 BMW MOTORRAD G 650 GS maintenance

Topping up engine oil
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Wipe the area around the fillerneck clean.
Remove oil dipstick1.
Damage to the enginecan result if it is operatedwithout enough oil, but the samealso applies if the oil level is toohigh.
Always make sure that the oillevel is correct.
Top up the engine oil to thespecified level.
Check the engine oil level(66).
Install the oil dipstick.
Brake system
Reliability
A fully functional brake system isa basic requirement for the roadsafety of your motorcycle.
Do not ride the motorcycle if youhave any doubts about the de-pendability of the brake system.
Under these circumstances havethe brake system checked by aspecialist workshop, preferablyan authorised BMW Motorraddealer.
Incorrect working practicesendanger the reliability ofthe brakes.
Have all work on the brake sys-
tem undertaken by trained andqualified specialists.
Check operation of the
brakes
Pull the handbrake lever.
The pressure point must beclearly perceptible.
Press the footbrake lever.
The pressure point must beclearly perceptible.
If pressure points are not clearlyperceptible:
Have the brakes checked by aspecialist workshop, preferablyan authorised BMW Motorraddealer.
Brake pads
Check the front brake pad
thickness
Make sure the ground is leveland firm and place the motor-cycle on its stand.

Visually inspect the brake padsto ascertain their thickness.Viewing direction: Between thespokes toward brake caliper1.
Brake disc thickness,front
min 1.0 mm (Friction padonly, without backingplate. The wear indicators(grooves) must be clearlyvisible.)
If the wear indicating marks areno longer clearly visible:
Brake pads worn past theminimum permissible thick-ness can cause a reduction inbraking efficiency and undercertain circumstances they can
cause damage to the brake sys-tem.
In order to ensure the dependab-ility of the brake system, do notpermit the brake pads to wearpast the minimum permissiblethickness.
Have the brake pads replacedby a specialist workshop,preferably an authorised BMWMotorrad dealer.
Checking rear brake pad
thickness
Make sure the ground is leveland firm and place the motor-cycle on its stand.

If the wear indicating mark is nolonger visible:
Brake pads worn past theminimum permissible thick-ness can cause a reduction inbraking efficiency and undercertain circumstances they cancause damage to the brake sys-tem.
In order to ensure the dependab-ility of the brake system, do notpermit the brake pads to wearpast the minimum permissiblethickness.
Have the brake pads replacedby a specialist workshop,preferably an authorised BMWMotorrad dealer.
Brake fluid
Check the brake-fluid
level, front brakes
A low fluid level in thebrake reservoir can allow airto penetrate the brake system.This significantly reduces brakingefficiency.
Check the brake-fluid level atregular intervals.
Make sure the ground is leveland firm and hold the motor-cycle upright.

with centre standOE
Make sure the ground is leveland firm and place the motor-cycle on its centre stand.
Move the handlebars to thestraight-ahead position.
Check the brake fluid level infront reservoir1.
Wear of the brake padscauses the brake fluid levelin the reservoir to sink.
Brake fluid level, front
DOT4 brake fluid
It is impermissible for thebrake fluid level to drop be-low the MIN mark. (Brake-fluid reservoir horizontal)
If the brake fluid level drops be-low the permitted level:
Have the defect rectified asquickly as possible by a spe-cialist workshop, preferablyan authorised BMW Motorraddealer.
Checking brake-fluid

A low fluid level in thebrake reservoir can allow airto penetrate the brake system.This significantly reduces brakingefficiency.
Check the brake-fluid level atregular intervals.
Make sure the ground is leveland firm and hold the motor-cycle upright.

Coolant
Checking coolant level
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Check the coolant level in ex-pansion tank1.

Coolant, specified level
between MIN and MAXmarks on the expansion tank
If the coolant drops below thepermitted level:
Top up the coolant.
Topping up coolant
Removing left side panel(98).
Open cap1of the coolant ex-pansion tank and top up thecoolant to the specified level.
Checking coolant level (72).
Close the cap of the coolantexpansion tank.
Install the left side panel(99).
Clutch
Checking clutch-lever
play
Pull the clutch lever until resist-ance is perceptible.
Measure clutch-lever playa.

Adjusting clutch-lever
play
Push back boot1.
Slacken nut2.
To increase clutch play: turnadjusting screw3clockwise.
To reduce clutch play: turn ad-justing screw3counter-clock-wise.
Checking clutch-lever play(73).
Repeat the steps in this pro-cedure until clutch play is setcorrectly.
Tighten nut2.
Pull boot1back over the ad-justing screw.
Tyres
Checking tyre tread depth
Your motorcycle's handlingand grip can be impairedeven before the tyres wear tothe minimum tyre tread depthpermitted by law.
Have the tyres changed in goodtime before they wear to theminimum permissible treaddepth.
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Measure the tyre tread depthin the main tread grooves withwear marks.
Tyres have wear indicatorsintegrated into the maintread grooves. The tyre is wornout when the tyre tread has worndown to the level of the marks.
The locations of the marks areindicated on the edge of the tyre,e.g. by the letters TI, TWI or byan arrow.
If the tyre tread is worn to minim-um:
Replace tyre or tyres, as applic-able.
Rims
Checking rims
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Visually inspect the rims fordefects.
Have damaged rims checkedand, if necessary, replaced by aspecialist workshop, preferablyan authorised BMW Motorraddealer.

Checking spokes
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Draw the handle of a screw-driver or a similar instrumentacross the spokes and listento the notes of the individualspokes.
If the notes vary:
Have the spokes checked by aspecialist workshop, preferablyan authorised BMW Motorraddealer.
Chain
Lubricating chain
Dirt, dust and inadequatelubrication will result in ac-celerated wear and significantlyshorten the drive chain's usefullife.
Clean and lubricate the drivechain at regular intervals.
Lubricate the drive chain every1000 km at the latest. Lubric-ate the chain more frequently ifthe motorcycle is ridden in wet,dusty or dirty conditions.
Switch the ignition off and se-lect neutral.
Clean the drive chain with asuitable cleaning product, dry itand apply chain lubricant.
Wipe off excess lubricant.
Checking chain sag
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Turn the rear wheel until itreaches the position with thelowest amount of chain sag.
Use a screwdriver to push thechain up and down and meas-ure differencea.
Chain deflection
35...45 mm (Motorcycle withno weight applied, supportedon its centre stand)
If measured value is outside per-mitted tolerance:
Adjust the chain sag (76).
