I need help!!!
Ok so I have a 2016 sportster 48 with a cobra fi2000r closed loop. I have cobra rpt slip ons and a stage 1 airl filter. Does anyone know what the pots should be adjusted to. I can't get my bike to run right
yeah what brown said up there
u can also try this
and welcome to the forum
Your Cobra Fi2000 fuel injection module has been tested and preset for best function and rideabilty
on a motorcycle in stock form. The Fi2000 does however, have 3 important adjustments that allow
you to tune the module for optimum performance, especially if you have performed other changes to
your motorcycle. These adjustments also allow you to resolve drivability issues if our stock settings
are not exactly right for your bike. Make sure your motorcycle is up to normal operating temperature
(15 minutes of riding should be sufficient) before making any adjustments.
Remove the door to expose the pots
GREEN LED POT (left pot) - With the Closed Loop function of this module you do not need to adjust this
setting, leave it at 3. Without a closed loop system this adjustment would affect idle and cruise fuel. If you
had cruising issues, this is where you would try a different setting. Generally, surging and uneven running
while cruising is a lean fuel condition, so adding a small increase in fuel by turning this adjustment
clockwise with a small flat blade screwdriver a 1/2 of a position would help. The bike would need to be
Test-driven to feel an improvement and only the setting would need to be increased until the surge went
away. Also, backfiring or popping on trailing throttle is generally a lean symptom (or an exhaust gasket
leak). The same small increases as above would be tried just until the backfiring would disappear.
YELLOW LED POT (middle pot) - this adjustment affects acceleration and power fuel. If you have a
hesitation or bogging on acceleration, this is where you would try a different setting. Aftermarket air
cleaner assemblies generally lean out fuel mixtures, so try small clockwise increases as above until a
smooth acceleration returns.
RED LED POT (right pot) - this adjustment is the top end or power fuel adjustment. Just like the main
jet in a carburetor, it starts to control fuel as you demand maximum power from your bike and takes
over completely above 4000 R.P.M. As performance gains are added to your motorcycle, such as big
bore kits, camshafts, flowed cylinder heads, etc., each component will increase the fuel demand of
the system. With the red pot turned to its maximum (10) position, the Fi2000 will cope with nearly 100
R.W. horsepower. An all-stock motor will only require a 2 position. You can generally, if you are
using quality performance engine upgrades, in a sensible combination equate the numbers evenly
from 2 up to 10 based on horsepower gains.
