While you are cleaning all of the connectors throw some dielectric grease on them too.

Put the carbs on and be done with it. Its very easy and your bike will run great and smother.
I just put carbs on my 2007 ktm 990 adventure and thats the best thing for the bike.

That's not off the table. How involved is it? Pretty much plug-n-play?

Which carbs? From a 950, or some exotic?

Hmmmm, not exactly for a shoe-string budget. We'll see where this goes. There is a lot I like about FI, and that may not even be my problem. Carbs are black-magic too... Thanks for the link.

Hope you get things worked out.

The cost is pretty substantial to do a Carb conversion for most... thought you might like to know the facts.

Forgot you are down in San Antone. Been In Austin for the last week. Crap, we could have got it figured out. You need to fix the Air inlet code straight away. As said on here before your bike is in a limp home mode. You can load different maps but nothing will happen. I'll be heading to Florida in January. Probably have time to stop for a day and we can throw the wide-band on her.

I just put carbs on my 2007 ktm 990 with abs and I spent $1200 + total and that was with bike on the dyno.

If you wanted to do it to your bike it could be done for a $1000.

I used the carbs, ecu, wire harness off a 2004 KTM 950.

My abs still works fine. I can help you with that.

You can see my dyno runs on advrider under ktm 990 adv carbureted dyno run.

If you have any questions call me 530-228-6446 Ceasar

I can help get the parts you need.

So by converting to carbs would I be eliminating ALL these sensors and such? Air inlet, O2s, could easily do the canni and SAS. Would the ECU stay (to control the other bike electronics like the dash, ABS, etc)? I guess my main question is: Would converting to carbs simplify the entire bike-system, or will I be chasing my tail by adding more PITA factor than it's worth by attempting an organ transplant?

Simple is good. As I grow as a motorcyclist this idea is becoming more prominent. Convince me.

Stick with it man. If you can get it out of limp mode I think all your problems will be solved.

I'd call a good KTM dealer that deals with LC8's specifically and just ask them what will make the ECU put the bike in a limp mode. Then I'd ask how to check those. Once this is done, just run down the list until you've found the fault.

If it's the Air Inlet Sensor that originally was throwing the code, replace it. Is it expensive? Don't know. But I do know that for the fuel mileage you're getting there is a sensor that's gone bad. Even if it's a few hundred dollars, it's still cheaper than carbs.

[KTMADV]

Yes it would eliminate all the sensors. Your new ecu will run your dash.Your abs will still work fine on and off.

Life is much better for me after I put the carbs on.

In the long run you will save money on parts plus better fuel mileage.

Give me a call and we can talk about it.

When my fp expired, it would starve the engine from time to time, especially when the bike run hot. Falling to its face was the effect, making the bike unrideable. If you need to experiment, I ensure you, you can use even a 3.0bar chinese fp from a car, transformed to suit. I am running one with no problems for 8 months or so. Cutting the aluminum extrusions to fit and the plastic connection protections is all is needed. Doesn't seat perfectly but seals where it is essential:

The cost of a chinese fp unit goes for 48€ over here. I guess you could get it at $40 at your side of the pond.
I believe the pressure regulator is very unlikely to malfunction. I cannot see dirt sitting there.
