Thank you for choosing the Techlusion Electronic Jet Kit.
The TFI is usable for all 2008 Yamaha Raider.
This product is a great fit for stock bikes with exhaust and
intake mods. It is also capable of handling the fuel needs
of cubic inch kits, light cams, and a variety of head port-
ing.
This is an Electronic Jet Kit. Like jet kits in the past, the
more you modify, the more responsibility you take in get-
ting your fuel curve right.
Due to the wide variety of applications we try to be very
generic with our instructions, so if you need further as-
sistance with an install call technical support at 877-764-
3337 or see our web site at:

INSTALLATION
(During the install or tuning please call for any or all
help, we can’t help if you don’t call.)
1. Remove the seat.
2. Remove the right hand side panel.
3. Remove the two bolts from the right hand chrome
ignition coil cover.
4. Route the TFI harness under the right hand
side of the frame and up above the cylinder head
following the frame towards the center of the engine
mount/ignition bracket.
5. Locate and disconnect the CLEAR 6 pin injector
sub-harness located behind the ignition coils
bracket.
6. Plug the TFI 6 pin connector into the bike’s 6-pin
connector so that the TFI is now in between the
bikes original connection.
7. Attach the ground to the stock grounding location
nexttheoilllcap.
8. Disconnect the BLACK O2 sensor connector, which
is located under the seat, on the Right Hand side of
the bike right next to the fuse holder.
9. Reassembly is the opposite of disassembly.
10. Start the motorcycle. The TFI is programmed “not”
to add fuel at idle. This “may” cause the LED’s to
ashatidle,thisisnormal.Somemodels“may”
have a solid green LED at idle, this is also normal.
IfthegreenorredLEDscontinueashingafter
startup, an injector wiring error is indicated.
Re-check the wire’s from the TFI and make sure
they are connected to the proper wire of your
motorcyle’s stock harness. MAKE SURE you have
the correct wires selected in the stock harness.
TUNING:
We suggest that you set your pots to the setting that best
matchesyourbikesmodication.Furtheradjustmentscan
bemadebyrsthavingyourMotorcyclefullywarmedup.
Then with a screwdriver in hand, locate the green light and
the pot right below it. Raise the RPM up to a high idle or
about 1800-RPM if you have a Tach. Once there, slowly
turn the green pot clockwise from the 1:00 position (or off)
until you achieve the highest RPM and smoothest running
sound (just like you would if you had a mixture screw on a
carburetor).Youshouldndthatthebestsettingisbetween
1:30 and 3:30.
Next locate the yellow light and the pot below it. This pot
adjustment acts as an accelerator pump adjustment. Any-
time you see the light on, it means that this pot is adding
fuel. You will notice that you can take the RPM slowly up
to 3000-4000 in neutral and see no yellow light. But whack
the throttle wide open quickly and you see the yellow light
come on. Try to add as much as you can until the bike says
it is too much then back off two clock positions. This yellow
pot adds most of its fuel below 4000 RPM and full throttle
acceleration.
The red light pot is for your main jet. It adds about 3 jet
sizes per clock position. For example: One clock position
is the same as 170 to a 185 main jet. All we can say about
setting up this pot is use the base setting that comes closest
toyourbikesmodications.Thenusethesamemethodyou
used, setting up your carbureted bikes.
The RPM switch controls when the red light comes on. The
more you turn it from the one ‘o clock position the higher the
RPM before the red turns on.

TROUBLESHOOTING:
Problems:
First it is important that you understand that all modern
day fuel injected Motorcycle’s have a big advantage over
carbureted Motorcycle’s. Fuel injected Motorcycle’s all
have the same exact fuel curve and is corrected every-
day by the on board weather station. Which means your
Motorcycle fuel map is either ideal or it needs a little. Just
likejetkitsdidforyouforyears.Ifyoundthatanything
you do with the pots make it worse, stop and check these
possibilities:
1. Engine not fully warmed up.
2. A vacuum leak on the intake.
FULL THROTTLE:
Simply add or subtract fuel with the red light pot to
determine if the problem is better or worse. This lets the
engine dictate additional adjustments or call tech support
at 877-764-3337.
