Hey Essie I just got off the phone with my ace mechanic buddy. He is pretty sure the dealership did not do the initialization process properly.

His remedy for the problem is as follows.

Delete and reset all the adaptation values

Reinstall factory map.

Now this is where most dealerships screw up the process. Start up the bike and do NOT touch the throttle until the engine temp sensor shows a minimum of 80 degrees C.

If the engine should die during this process just hit the start button to relight the motor, but whatever you do do NOT touch the throttle. Don't worry if you have to hit the start button multiple times during the process.

He said this should fix most problems guys are having.

He also said that when riding the bike and coming to a stop do NOT just pull in the clutch while rolling along say at 20 mph and hold it in until you are stopped. Doing this will cause the ecu to richen up the fuel map which can lead to other issues.

Like a said earlier, this ECU system is complex beyond our realization and if not setup and used correctly can lead to problems.

Good luck and let me know what happens.

I also sent this to you on a PM.
Thank you very much, HJ. Just thought acknowledgement was appropriate here as well as via PM.

Hey thanks Fred. That stuff is fascinating but way above my pay grade.

I appreciate you posting it as it helps me wrap my peanut brain around what is going on. Kind of a picture is worth a thousand words moment.

Cheers mate.

No problem and figured it might answer some questions about 'resetting' things in the bike.

I've been super annoyed with Texa and their lack of 790 support!!! Not a cheap tool either. Hopefully next week as there is meant to be an update coming

Well it's all Greek to me, but much appreciated by me for future reference, so that's a thankyou from me, too.

Thanks to everyone for their input. Got the bike back from the dealer today and heading out for a ride tomorrow.
According to the dealer they needed to reset the adaption values which apparently relates to the sensor ranges. This is similar, if not the same remedy as outlined earlier in this thread by @Hawkerjet (thanks mate!).
Anyway after discussing with the dealer (and prompting them with the aforementioned post) they did the following under warranty:
Connect KTM diagnostic and read faults - no realted faults stored.
Reset adaption values and teach in base sensor readings with no throttle warm-up.


I also had them do an oil a filter changes as I've done 6.5k since I picked the bike up in August and noticed that they used 10W 60 oil which apparently KTM have advised them to use in our warmer climate. I have noticed that the my engine temp is pretyy consistent at 4 bars when running and the engine certainly throws of a bunch of radiant heat so this makes sense.

I'll be sure and repost if the issue isn't resolved.

Good news, F12.

My own update is happily uneventful. Apart from a bit of revving on startup on changing back to street mode from sport, all is good. He's still being a very good boy.

One niggle definitely not confined to KTM, is the tendency for the chain to unadjust itself on retightening. A good whack to the tyre before doing that fixed it. I was wondering why the left peg was vibrating at higher revs after downshifting... my partner had a squizz and sure enough... My SV did the same thing sometimes, but without the warning sign.

Hiyas!
Week 4 of 790 ownership.
Absolutely loving the ride, despite the intermittent engine shutoffs while shifting gears. Took him back to the shop again today to get them to look harder after another instance with no luck pinpointing why at his 1000km service last week.
Fingers crossed it's an easy fix.
Here he is with his little bro.

G'day Essie from the left coast of Canada, Sounds like you got either a sensor issue or a connection or both? But as stated here, i'd get another opinion if your current shop is lost.
Good luck.

Thanks Gare.
Periodically the bike will still rev to 4k on a cold start.
Video sent to dealer of origin a week ago with no response.
A couple of questionable things with the 390's first service as well, meaning yes, no more dealings with this mob unless necessary or emergency-related.
The nearest one from them is an hour away but thesame business unfortunately. We're feeling a bit stuck to be honest.

A very interesting possible development, perhaps.
Still no response from the dealer regarding the video of the revvy start we sent them several weeks ago. Oh well.

Anyhoo, the bike still does that, as well as the odd cutout.
This morning it cut out again from 3rd to 2nd.
Tonight my partner asked why I reset the tripmeters. What? Not me, Babe.
Seems the cutouts might also cause a reset of data. Trips, not odo affected.
It's a long shot, but not beyond the realms of possibility.
Unfortunately we can't be sure because I haven't really done anything with the tripmeters except make a mental note while out on weekend rides.
Tonight however partner was filling the tank, four days after the last fill, and happened to notice there were only the number of KMs used for today's commute on the dash (both meters), which is very strange.
When he mentioned it, the penny dropped and I recalled this morning's cutout.
I will definitely check the trip data next time it happens.

Essie I don't have the cutout issue but my trip meter began resetting on it's own a couple of weeks ago. Very strange.

Actually I did have a couple of cut outs when I first got the bike. Mine was due to my foot lightly touching the shift lever. The solution was to disable the quick shifter. Never a problem since. Is your quick shifter selected on?

My bike did the rev up on start a couple of times when brand new but has not done since. I now have 3700 miles on the bike.

Sure hope you get things sorted out.

Cheers.

Ugga is being dropped off at the dealer today for more exploratory surgery in the morning.
In conjunction with KTM remotely , he will be monitored from a cold start with a new battery and a new throttle body. Most likely also, another ECU reset.


The tripmeter does indeed wipe itself on cutout rather than restart, I found out yesterday.

This morning he did the rev on cold start-up not once, but again once the usual one settled down. Neighbours wouldn't be too impressed with a double dose of revvyness at 5am.

Fingers crossed it gets sorted at last, before I set off on my epic adventure in two weeks!

@Essie hope this gets sorted for you. Where will the adventure take you??

Who's a very good boy?
Ugga's still in the shop, but...

At long last, he finally did all of his bad things this morning 🕺

KTM Australia were also plugged into him remotely at the time, as they were for a flawless start with new battery yesterday.
So, now I'm SOOOOO relieved that it's not only me who has seen him do all his things. It's not me, it's him.
Revvy start, cutout and the other stuff like the tripmeters etc, all witnessed by those who can do something.

Tomorrow KTM are supposed to be resetting the ECU -I'd be replacing it - and working out other possible solutions. No further mention of throttle bodies, however.
I expect to know more tomorrow.

There is no "resetting the ECU" as such but you can clear some learned values i.e. fuel table from the lambda sensors below around 4000rpm. It's called clearing the adaptations which will clear the learned values. See my screenshot above, the options for the 790 are even less.

Usually you have to run the bike at idle until the fan comes on and without touching the throttle after clearing the values

Rather pointless exercise in your case if this has already been done before.

Ah, yes. Thank you. Now it's clearer, and hopefully I can ask more relevant questions regarding their terminology.
I still feel I'm being kept i n the dark to some extent, especially with the service dept. using terms like 'ECU reset' themselves. I look forward to getting to query that, given their reluctance (refusal) to give me paperwork for the last 'fix'. I'll be pushing harder for that too.

Got him back on Friday. No issues over the weekend. Yay.

This morning however, he did it all again.
Aaaaaaarrrgh!
