Coolant Temperature Gauge
When the needle begins to move above the
C (Cold) mark, the engine is warm enough
for the motorcycle to be ridden. The normal
operating temperature range is within the
section between the H and C marks. If the
needle reaches the H (Hot) mark, stop the
engine and check the reserve tank coolant
level. Read pages 20 — 21 and do not ride
the motorcycle until the problem has been
corrected.
