Throttle Body Cleaning; Inspection - Suzuki GSX-R750 Service Manual

THROTTLE BODY CLEANING

"
Some carburetor cleaning chemicals, especially dip-type
soaking solutions, are very corrosive and must be
handled carefully. Always follow the chemical
manufacturer's instructions on proper use, handling and
storage.
• Clean all passageways with a spray-type carburetor cleaner
and blow dry with compressed air.
#
Do not use wire to clean passageways. Wire can damage
passageways. If the components cannot be cleaned with
a spray cleaner it may be necessary to use a dip-type
cleaning solution and allow them to soak. Always follow
the chemical manufacturer's instructions for proper use
and cleaning of the throttle body components. Do not
apply carburetor cleaning chemicals to the rubber and
plastic materials.
