I would love to peak at a tech manual for an 05 and look at the diagrams for the carbed bike. I'm not sure if they still triggered the ignition from the cam or the crank. If they used the crank sensor couldn't a guy use the 05 carbed electronics and wiring?

I've got the '05 Service Manual, but never paid any attention to the sections that deal with carbed bikes ... I may take a look and let you know what the deal is ... don't hold your breath, though, 'cause I may forget to ....

Why? It would be alot easier and cheaper to just wire into the existing harness than to change out the harness.

That's what I thought.

The crank position sensor is the input to the ignition control module for timing for the '05 carb FXD models ...
Also ... the ignition for the carb models is electronic, so potentially subject to 'gremlins' ... unless you revert and retrofit your bike with 'points ignition' ....
Magneto anyone ...? I understand those are kind of 'spendy' ....

Those looking at ignition systems that will support a carb setup (upon removal of EFI system) might consider the S&S ISTtm Ignition (Intelligent Spark Technology) ... "Optional Guardian Diagnostic System allows engine builder increased flexibility and control." http://www.sscycle.com/product/cart....detail&p=20575
I understand that there are a few online distributors of S&S that discount their suggested retail prices ... but, aren't allowed to show them on their websites (say 'call for pricing') ....
I'd be interested in seeing how much adjustment is possible by the user/tuner with some of the other options ... Altman, Accel, H-D stock (take off), etc ...
I understand my ThunderMax allows for adjusting the ignition advance curve ... although it isn't recommended (the tech pub has a section on how to eliminate pinging/detonation by retarding spark advance in the affected RPM range) ...
The MoCo service manual states that spark advance ranges from 0 to 50 degrees (determined 'automatically' ... i.e., preprogrammed values) ...

Is that all the Thundermax allows you to adjust is the advance? It seems like there would be more options... I had an Dyna (brand not the bike) nose cone ign in my chop that you could select different curves by simply changing settings on dip switches. They were preset curves but the one I used happened to work perfectly. You could also adjust rev limit ect.
P.S. scored me an intake manifold off of ebay. Having second thoughts about using my 40mm cv. Read that it would run well on engines up to 95ci but that doesnt leave a lot of room for engine mods (cams head work ect) May use it on the stock motor and upgrade later.
There was a killer Twincam kit on the bay that included everything you'd need to convert. 51mm screaming eagle carb with matching SE intake manifold, air cleaner and all the gaskets, brackets ect, went for $450.00 If I were to spend that much Id rather have a Mikuni kit.

Plenty of guys have done it. If that's your thing then, hey have fun.
I'll keep my EFI. Living up here in the Northland and riding when temps are around 0, I like not ****ing with the choke and having a bike that starts right up. For 10 years of street riding before I got the EFI I screwed with the carbs. The only way I am going back is if I get me a Shovel as a second bike. Technology is a good thing.
If I want to spend time screwing with carbs I'll buy another money pit, I mean snowmobile.
