Bought the bike brand new from my dealership 08/04/18. Had 0.1 hours on her. Took her home and did insane amount of heat cycles, pretty much like the manual states.1st-2nd heat cycles were just warming the bike up and riding in 1st gear at low rpm and then having the bike completely cool down. 3rd-5th heat cycles were going through the gears and low rpms and for about 20 min. 6th-8th heat cycles were the same but a little more rpm(manual says not to go over 7k for the first hour but I don't know where 7k is but I'm positive i didn't). Ended up finishing the heats cycles at 1.2 hours, changed the oil and filter, had metal shavings obviously.
That same day I started cruising the bike around my little track, going through all the gears, getting a feel for her and all. Up until 3.1 hours(manual states not to go over 75% until 3 hours). All ways good!
Next day I take her to the track and made sure to do another "safe" heat cycle which involved me taking the bike off the truck and letting her warm up for about 7min at idle while I geared up and checked everything and then turning her off and letting her cool completely down. After that I took her on the track and did 3 laps of just cruising. Going through all the gears again and just barely making it up certain sections because I was going easy easy easy. Again let her cool down completely then started to shred. She had 3.4 hours when I started ripping!
Anyways when I engine break I have this little back fire, like a carbureted bike has when it's running to lean. It's not a pop, but more of a puff puff puff. My dealerships says that resetting the ecu should help with that but it won't go away completely. I hear some ktms do it but not as much as mine. I'll upload videos of the sounds after I get done with this.
End of the day take her home get her all cleaned up blah blah blah. 4.1 hours I change the oil and filter, very clean! After I changed the oil I tried to start her to let her cycle and it won't start. Pull the choke and still nothing. She'll start if I give her some gas but she will give me attitude about it. After I start her and let her run for 5 seconds, she doesn't have a problem start with just the push of the button no gas.
This is my first ktm other than when I was on 50's so this is allllllll new to me. Would definitely appreciate some answer to help with my worries! I'm so meticulous about my bike and it's really frustrating me because what she's doing doesn't sound all that right. Thank you in advance.

You can hear the little puff when I'm in the air
Here's the cold start issue
The Shop
You need a multimeter and a bit of a wiring rig to get a reading. If youre totally new, id suggest having your dealer set it for you. If you do it wrong it can get messy. Pressure from your finger on that sensor can change the setting - its THAT sensitive to change.
TPS tool
1st- Don't let the bike idle for 7 minutes. It's just not needed.
2- When it pops in the air isn't that decel pop meaning it's too rich?
3- Try removing the backfire screen on your filter cage or get a 2 stroke filter cage to get some more air in there if needed.
4- Shift up when you hit the rev limiter between the 2 jumps.
But in all reality, your bike is fine, just needs some Ecu tuning or opening up to let her breathe. You have to image the factory is setting the air fuel in a generic setting(Typically So Cal). So if your more humid, elevation, bike hot from rev limiter, it’s all going to effect that popping.
Does it pop on both maps? That could give you some idea if it’s lean or rich. The aggressive map will be more lean.
Twisted Development has great maps for these bikes, you can send the Ecu and they will drop in a new map.
Mine does the exact same thing. Sometimes I have to crack the throttle open to get it to fire up. No biggie.
