Suzuki GSX-R 1000 Service Manual: Engine top side disassembly
It is unnecessary to remove the engine assembly from the frame when servicing the cylinder head cover and camshafts.
| Note before servicing the engine top side components (until camshafts removal) with the engine in place, remove the following parts:
Other parts except for these “engine top side components” can not be serviced with the engine installed in the frame. Refer to “engine assembly removal” and “engine assembly installation” . |
| Caution identify the position of each removed part. Organize the parts in their respective groups (e.G., Intake, exhaust) so that they can be reinstalled in their original positions. |
Cylinder head cover
- Remove the spark plugs. Refer to “ignition coil and spark plug removal and installation” in section 1h .
- Remove the cylinder head cover (1) and its gasket.
- Remove the dowel pins and o-rings.
Camshafts
- Remove the valve timing inspection cap (1).
- Turn the crankshaft to bring the line “a” on the ckp sensor rotor to the slit “b” of cap hole thread and also to bring the camshafts to the position as shown.
- Remove the cam chain tension adjuster (2).
- Remove the gasket (3).
- Remove the cam chain guide no. 2 (4).
- Remove the camshaft journal holders (5).
| Caution be sure to loosen the camshaft journal holder bolts evenly by shifting the wrench in the descending order of numbers. |
- Remove the dowel pins.
- Remove the intake camshaft (6) and exhaust camshaft (7).
Cylinder head
| Note the cylinder head can not be serviced with the engine installed in the frame. |
- Disconnect the water bypass hose (1).
- Remove the cylinder head bolts (m6) (2).
- Remove the cylinder head bolts (m10) and washers.

Injection timing description
Injection time (injection volume)
The factors to determine the injection time include the basic fuel injection
time, which is calculated on the basis of the
intake air pressure, engine speed and throttle opening angle, and various
compensations. These compensations are
determined according to ...
Camshaft inspection
Refer to “engine top side disassembly” .
Refer to “engine top side assembly” .
Camshaft identification
The exhaust camshaft has the embossed letters “ex”
and the intake camshaft has the embossed letters “in”.
Cam wear
Check the camshaft for wear or damage.

Continuity check
Measure resistance across coupler “b” (between “a”
and “c” in figure).
If no continuity is indicated (infinity or over limit), the
circuit is open between terminals “a” and “c”.
Disconnect the coupler “b” and measure resistance
between couplers “a” and “b-1”.
If no continuity ...
