RST mille
USA
Remove the pressure regulator hose (11).
Loosen the two clamps (14-15).
WARNING
Be extremely careful when removing the throttle
body (6), since it remains attached to the fuel tank
(13) by means of the fuel hose (12).
Before removing the throttle body, you must
thoroughly clean the two intake flanges, to prevent
foreign matter from entering the cylinders.
Firmly grasp the throttle body (6), and gradually wiggle
it back and forth while pulling upward, until you are able
to slide it off the inlet manifolds.
Place the complete throttle body assembly (6) and fuel
tank (13), still attached together, on a clean surface.
Plug the inlet manifolds to prevent foreign matter from
entering the cylinders.
WARNING
During reassembly:
- the fuel delivery line (12) must not be twisted, or
placed where it is likely to be pinched by other
components; it must be replaced if found to be
damaged or deteriorated;
- the fuel delivery line (12) must be placed so that it
arrives on the right-hand side of the throttle body
(6), passing under the body between the two intake
flanges;
- the throttle body (6) must be fitted perfectly on the
intake flanges;
- the clamps (14-15) must be properly tightened.
When replacing the throttle body (6), you must align the
throttle valve position sensor, see 4.10.6 (ALIGNING
THE THROTTLE VALVE POSITION SENSOR).
