8. Air Funnel Set (Bell-Mouth Set) (5SL-A4460-70)
Installation Precautions:
1. Install the joint and funnel so that the air filter is located in-between. Before
installation, remove the plate attached under the STD air filter case and then the STD
funnel.
2. Install the funnel and joint after applying a thin coat of grease to their threads. They
may have a little gap between them and the case but do not become loose with the
STD rubber joint and plate fastened.
3. For the standard settings, use the 9 mm funnel for the #1 and #4 cylinders and the 24
mm funnel for the #2 and #3 cylinders. This combination may change according to
the exhaust pipe specifications or to the rider’s preference.
4. Tendency subject to the funnel combination is as follows:
When the longer STD funnel is used for the #2 and #3 cylinders, power tends to be
weaker in the high rev range but easier to handle in the medium-rev range.
When the shorter STD funnel is used, the engine tends to be more responsive in the
high-rev range but produce less torque in the medium-rev range.
9. Air Filter Element Assembly
This air element is an improvement on the STD with an increased 20% of intake
efficiency. The raising in the air passage sheds water, so the element is also effective in a
run in rainy weather. Regular maintenance is simple; simply blow air on the back of the
element.
