How much to convert back to carb?

[1bdBagr]

I'd been f-ckn' around and not got my manuals(s) yet....my local dealer never has 'em in stock when i want them (and not at a good price, either)....so, I ordered them from zanottis today. At least i got the good price, as they didn't have them in stock either. Damn...doesn't ANY friggin dealer STOCK anything anymore? So, when that comes, i'll hopefully find out what right part # harness is needed for a 2000. Been also working on my spare sheet metal for my paint scheme (discussed on another thread in paint & bodywork). I figured i'm less apt to not miss out on summer riding, by doing the paint/sheetmetal switchover first , then do the engine/heads/cams/gear drive/CARB SWITCH all at once maybe AFTER Labor Day. At least that's my plan...Thanks for the replies.

TMAT. Worth every dime, although a lot of dimes.

From what I read you just have the dealer program you VIN into new ECM.

Have to admit I considered this. I got manifold and CV40 from 01, not sure if would fit. Still need another $300 ignition and other stuff.

But I decided to put my money where my mouth was. FI is superior, when done right and gives you more control. A carb is limited in what adjustments you can do to it.

IMO, only owed FI for a day, is that there is lack of understand and lack of good techs.

Sorry to bring an old thread back to life. But, has anyone that's done the conversion used the stock EFI coil. I have heard conflicting stories about using the EFI coil...some say it can't be done. I read posts stating that coil 31655-99 was the needed coil. However, that coil won't bolt up to my 2000 RK. It's totally different from the stock EFI coil as far as bolt pattern and the way the wires plug in. So, what I'm asking is what coil you guys have used to pull off the conversion. Thanks!

i dont think i have read anything about changing the tank from a EFI to a Carb tank!!! is this not nessarsy to get the bike to run "right"????

On my 2000 RK, when I pulled off the EFI ignition harness, I just unplugged the connector from the coil and plugged the new carb type ignition harness connector in. The coil doesn't know or care if an ECM or an ignition module is giving it orders to fire. In other words, your stock 2000 RK coil should work either way.

That being said, I believe some later years did have differing voltages to the coil, which could cause issues if you try to mix and match.

Yep, you have to get the quick disconnect fuel fittings off of the tank and plug one hole and put an adapter in the other one for a petcock. I used the Pingel kit made for this swap. I also removed the inner tank hoses, fuel pump, and filter.

That's pretty much what I had thought too. The only issue I was aware of was the addition of a 4th wire for the ion sensing. I'm guessing that came out with the Delphi FI and doesn't affect us doing the swap on a MM FI. But, I keep reading posts where people are saying they did the conversion and needed/used the 31655-99 coil. It's very confusing when people post these kinds of things without validating it first. That's why I was hoping to hear from some folks that ACTUALLY DID the conversion, to find out what coil they used.

Anyway, if anyone else that did the conversion is reading this please chime in with what coil you used.

1) If you used the stock coil, did you have any issues or mods you did in that respect.

2) If, for some reason, you changed the coil, using a different HD part number, please post your reasoning behind this change.

I'm sure I'm not the only one that's interested in knowing this. Hopefully by clearing this up it will save someone else from buying a part they don't need to pull off this job. Ancient Iron: thanks for responding!!

Swapped my 01 FLHTC. Best mod so far. Used the stock coil with no issues. Buy an 03 and up ignition and you can leave the cam sensor unplugged as well. Including the money I got reselling my old e.f.i. and pciii this conv. only cost me $400. Money well spent.

Thanks. I just ordered the 32435-00 harness and a bunch of the small crap. All I need now is a carb and ignition module. I was under the impression the 2001's and up did away with the cam sensor...no? Anyway, with the -00 harness I'll have the option to go either way.

I'm still a little unsure about the modules though. There's quite a few on ebay but finding the right part number isn't working out. They just list them by year but no part number. What I'm not sure about is the differences. They say TC, xx - xx year, but no P/N. So I'm not sure if what they're selling is for a Touring bike or something else. My guess is the different part numbers may be correct for TC and year, but may have different timing curves and setting for different model bikes. If someone can shed some light on this it would be great.

Thanks for the help!

Where are you in Texas? I'm in Houston if u need any help. Was a really easy deal. Took about 5hrs from running fuel injection to running carb. Not sure what year they stopped the cam sensor mines an 01 and has/had one. You gonna go C.V. carb or something different? I have a C.V. and with a 2-1, 203 cams and a high flow I'm getting consistent 40 m.p.g. That's with just me and my stuff.

I used an SE 32719-01A module I got off EBAY nib for $45. Working great. I also opted for the Mikuni HSR 42 carb. Very pleased with it also. I used the same harness you ordered, no problems.

James I'm just north of Austin. I got a CV40 from a friend for 75 so I will run that to get it up and running. I really haven't heard many bad reviews on the stock CV's so I'll run that for a while and see how it goes.

Thanks. The last thing I need as of today is the ICM. I will keep looking on ebay. For what HD is asking it doesn't make sense to buy a new OEM control module if I can catch a deal on something a little better off ebay or somewhere else.

Just a side note. My bike is a 2000 and the coil part numbers are the same for both EFI and carb. So, anyone that's considering the swap you should double check all the part numbers between EFI and carb before buying a coil. Some of the posts I have found are saying you need to pick up a different coil. As in my case, that isn't so. So check the part numbers between both models if it applies.

I got the wrong adapter for the tank. I should have just got the Pingel stuff from the start. What petcock did you guys use? Did the outlet point forwards or to the right of the bike? Thanks.
