BoonDocker YAMAHA YZ-F: YZ450F Box - Manual (Page 2)

Position the → (cursor) next to “FUEL” and press the SEL button to advance to the first fuel “rpm”
screen.
There are two fuel (rpm) screens. These screens will allow the user to make fueling adjustment
according to RPM only. The values set in these two rpm screens will adjust fueling according to the
corresponding RPM ranges regardless of boost pressure. Each of the fuel screens are labeled with that
screen’s corresponding RPM in the lower left hand corner of the display and have four adjustment
points: 0, 33, 66, and 99. These adjustment points represent a given throttle position (TPS) percentage,
0% being no throttle and 99% being full throttle. The two digit number below each TPS value represents
the amount of fuel that will be added (or subtracted) to the given RPM and TPS range. Each of the RPM
ranges blend into each other and taper off to zero as demonstrated in the RPM figure below. Each TPS
range blends to the previous and next adjustment point as demonstrated in the TPS figure below.
To make adjustments, use the left and right arrow buttons to position the →(cursor) next to the
appropriate TPS value and use the up and down buttons to increase or decrease the fuel value.
To advance to the next screen press the SEL button.
