'06 Carb to '07 Fuel Injection Conversion

[4-pac]

5 mile test ride I noticed the shifter shaft seal trying to pop itself out of the primary cover, back to the garage. Clean all the oil off the seal and cover, still can’t get it to stay. Off to the auto part place for a tube of contact cement and an o-ring (5/8 OD x ½” ID x 1/8” thick) to put some extra pressure on the seal from the outside. The extra o-ring is next to the shifter peg.



50 mile test ride.



I really like the way the bike runs now. Smoother, albeit higher idle. Much smoother throttle response and the power just feels better all around. I’m really diggin the SuperTrapp 2x2s. As per their recommendation, I went with 12 disk per pipe to keep the noise down. I’m not sure if the previous owner ever had a stage 1 programming job done to the ECM, but I have to say so far I have not noticed any bad traits with the SE A/C and ‘Trapps. I also like the fact that the exhaust is now behind my head, compared to my Screaming Eagle (the loud ones) slip-ons. At highway speeds, wind noise is louder than the exhaust.

Lesson Learned:

• Having a great running bike makes all the hard work and frustration worth it.
• Never start an 8 day project 4 days before a road trip

EFI Conversion Shopping list:

• EFI intake complete with electronics
• Main harness and harness caddies
• Instrument harness (must end with a “-07” don't belive the parts catalog on this one)
• 07 handlebar switch housings, left has clutch switch and both sides have different connectors than previous years
• 07 throttle cables (longer than my carbed Custom)
• ECM preferably with a matched TSM/TSSM/HFSS and fobs/antenna if necessary
• Stator
• Primary cover gasket set
• Voltage regulator
• Coil and mount
• EFI Heads and temp sensor
• Gaskets to match year model heads and rocker boxes
• EFI tank and rear fender
• EFI pump and ECM mount tray
• EFI exhaust & O2 sensors
• EFI air cleaner, carb version will have a gap
• 14mm x 10mm x 2mm o-ring for tank fitting just incase

Special Tools:

• 4” door hinge for primary drive disassembly
• 1-1/8” socket for crank nut
• 1-3/16” for clutch nut
• 250 ft-lb torque wrench
• ½” sensor socket
• O2 sensor socket

if I think of anything else I'll update

Other things I forgot:

• '07+ clutch lever (for clutch interlock switch)
• '07 plug wires
• You might consider an '07 Speedo too. Mine works but the diag test does not understand the ECM. And compared to a GPS, the speedo is registering 3 MPH fast. 70 on the speedo shows 67 on the GPS (I should put more faith in the government than HD, right? ). I haven't got the tank low enough to see if the fuel light comes on. Let you know in about another 50 miles...

Thank you for sharing this experience with us.

As a automotive tech, I will get customers from time to time who either have found a nice car that they want changed over to a manual Tran, or, they have found a really clean 2x4 truck that they want to know how much to make it a 4x4.

Unless you do a couple of these, you really do not know just how expensive it really is to do something like that, as a rule, it cost twice as much to do as it would if you bought it as a 4x4 or manual.

Right on, man! Great write-up, and great results! Kudos to you.

Congrats on your conversion. Great details on the project. Seems like a lot of work. How much did it cost? I agree it's harder to work with a hangover than to work drunk.

I gotta ask, how much did this project run ya?

[4-pac]

I appreciate the compliments guys. A lot of work, maybe for some. But for me, it’s a hobby. I’m a “builder” by nature. I grew up around sprint car and GT1 racing. Hot rods in my early years. Other hobbies include model R/C airplanes (park fliers to 150cc powered 1/3 scale aerobats) and DIY CNC systems. And professionally, I work in the IT field managing network support and build software code. Yep, I love to build things. It keeps my mind and hands working. And it provides me great satisfaction when it’s all said and done. Then I’m off to my next project…

Funny you say that. I worked in the speed shop business for 7 years and that's close to what I'd tell my customers: It'll cost you twice as much and take you twice as long than your original estimate...

Cost grouped by purchases:

EFI intake complete with electronics
Main harness
07 throttle cables
Voltage regulator
Coil and mount
EFI tank and rear fender (plus another front fender)
EFI pump and ECM mount tray
O2 Sensors
TSM Module
$550.00 ebay

07 hand controls, left has clutch switch and both sides have different connectors than previous years
$66.99 pr. ebay

'07 hand levers
$33.90

Stator
$19.98 ebay

ECM preferably with a matched TSM/TSSM/HFSS and fobs/antenna if necessary
$250.00 hdforum

EFI Heads and temp sensor
EFI air cleaner, carb version will have a gap
Primary cover gasket set
Head Gaskets
$824.50 ebay

EFI exhaust (complete Nightster set)
$40.50 ebay

Instrument harness (must end with a “-07”)
$65.01 Zanotti’s

Gaskets to match rocker boxes
$21.81 local dealer

14mm x 10mm x 2mm o-ring for tank fitting
$0.99

TOTAL
$1873.68

A couple of things to note:
I spent another $26.00 to get the instrument harness straightened out…
The ECM purchase came with another main wiring harness, HFSS (but no fob or antenna), fuel pump, and complete intake manifold with electronics
The Screaming Eagle 1200cc Conversion kit has a set of jugs and pistons that are sitting on the shelf
I included the cost of the Nightster exhaust, because at bare minimum, that is what it would have cost me for the conversion.

At this point, I have no intentions of selling off my original ’06 parts.
But as far as the spare EFI parts, there’s a little money that can be made back.

So about $2k and a bit of time finding the stuff - You'd BETTER like to thiker with that ROI

Good job though...

Kev

[4-pac]

Thanks Kev!

I have found it's a lot better ROI than my 1/3 aerobats. A 150cc DA engine (16 sweet HP) cost $1500 alone. Another $2500+ in airframe and electronics. And to have that baby burn herself into the runway and self destruct cause some jacka$$ qued up his radio on my frequency That's about the time I decided to switch hobbies.


For me it's more than the ride. I think my next project will be a Redneck Mutant...

[pquirk]

Great write up. You're a nutty dude though...not that there's anything wrong with that .
