Gear Ratios

CAUTION – TRAINING THE MSU FOR GEAR POSITION IS BEST DONE ON A
PIT STAND, OUTSIDE AND WITH THE HELP OF A FRIEND.
11.
Place your motorcycle on a flat, smooth surface on a secure rear center stand with no
obstructions in front of you, in case the bike falls forward.
12.
Replace the helmet on your head so that you can see the display and turn the HMD unit on
if it has turned off
13.
With the motorcycle ignition in the “OFF” position, push and hold the button on the side of
the MSU marked “B”, while turning the ignition to the “ON” position.
CAUTION - DO
NOT START THE MOTORCYCLE YET.
14.
The display should begin showing the word
“
MENU
”,
release the “B” button.
15.
Now push the “B” button again and the display should show
“
LEARN
”
.
Push “B”
again and the number
“
1
”
will begin to flash on the right side of the display. The
MSU is now ready to learn your motorcycle gear ratios
.
16.
Make sure the motorcycles Neutral indicator shows “N” and start your motorcycle.
17.
The gear indicator should be flashing a
“1”
on the right side of the display.
Standing on
the same side of your motorcycle as the shift lever, pull in the clutch and put your
motorcycle in 1
st
gear. Let the clutch out slowly and increase the RPM to approximately
3000 and you should then see the speed indicator and the RPM begin to move higher.
18.
The gear indicator will flash five times and then the SportVue will begin data sampling to
learn this gear
19.
When it is done learning that gear, the display will change to
“SHIFT”.
20.
You should now shift up to the next gear. The gear indicator should be flashing
“2”
and will flash five times before it begins sampling to learn 2
nd
gear.
21.
This will continue through 6 gears. If your bike only has 5 gears, simply leave it in top
gear when you are asked to switch to 6
th
gear.
22.
It is important that the bike be moderately accelerating when the SportVue does the
sampling. If the bike is coasting or decelerating when sampling occurs, inaccuracy in the
gear indication can occur. Sampling occurs after the 5
th
flash of the gear number. (See Fig.
15 below)
