Replacing The Clutch Master Cylinder (Fjr13Ae Only) - Yamaha FJR13AEV(C) Service Manual

• Refill with the same type of clutch fluid that
is already in the system. Mixing clutch flu-
ids may result in a harmful chemical reac-
tion, leading to poor clutch performance.
• When refilling, be careful that water does
not enter the clutch fluid reservoir. Water
will significantly lower the boiling point of
the clutch fluid and could cause vapor lock.

Clutch fluid may damage painted surfaces or

spilt clutch fluid immediately.
NOTE:
In order to ensure a correct reading of the clutch
fluid level, make sure the top of the reservoir is
horizontal.
