Tester knob indication resistance (Ω) Isc valve continuity ∞Ω¶ (infinity) (terminal . Ground)
Isc valve resistance approx. 80 Ω at 20 °c (68 °f) (terminal: “a” – terminal: “b”, terminal: “c” – terminal: “d”) Is the resistance ok? |
If wire is ok, intermittent trouble or faulty ecm. | Replace the isc valve with a new one. Refer to “throttle body removal and installation” in section 1d (page 1d- 10). |
Active control inspection (isc rpm control)
Check 1
Check 2
Check 3
Check 4
Note be careful not to increase the “spec” to 2 000 rpm, or the “engine speed” may reach the upper limit. |
If the isc valve does not function properly, inspect the isc valve or replace the isc valve. Refer to “dtc “c40” (p0505 / p0506 / p0507): isc valve circuit malfunction” or “throttle body disassembly and assembly” in section 1d .
Brakes
This motorcycle has front and
rear disk brakes.
Warning
Failure to inspect and properly
maintain the brakes increases
your chance of having an accident.
Inspect the brake system
before each use according to
the inspection before
riding section. Follow the
maintenance ...
Valve seat repair
The valve seats (1) for both the intake and exhaust
valves are machined to three different angles. The seat
contact surface is cut at 45°.

Using the testers
Incorrectly connecting the (+) and (.) Probes may
cause the inside of the tester to be burned.
If the voltage and current are not known, make
measurements using the highest range.
When measuring the resistance with the multi-circuit
tester (1), ∞ will be shown as 10.00 ...
