Re: KTM Duke 390 - Ownership Reviews and Experiences

Been a long time since I messaged here, probably more than 4 years. Want to let you all know, my 2015 model has served me very well and is still performing greatly.

I wanted to know what parts of new gen Duke 390 can be retrofitted to the old 2015 gen Duke? Help will be greatly appreciated.

Re: KTM Duke 390 - Owners Reviews and Experiences

Hi faizan,

How did you finally resolve this issue? Do you remember any details?

Re: KTM Duke 390 - Ownership Reviews and Experiences

Hi Rohith Rot,

Are you still using the duke 390? i need help on the same issue? any leads can help

Re: KTM Duke 390 - Ownership Reviews and Experiences

Hi i tried to upload it full resolution but it failed. Attaching a hopefully better image

Re: KTM Duke 390 - Ownership Reviews and Experiences

Thanks for sharing this ,but the image is not soo clear. on Zooming in,, the numbers get distorted.
Can you share a higher resolution pic.

Anyone tried the autofy anti theft lock on duke 390? If yes, need more info on this please.

Re: KTM Duke 390 - Ownership Reviews and Experiences

i think i mentioned it earlier too.. but let me say it again, did you get the throttle body, injectors cleaned. i remember your tank was filled up some crap. did you change the fuel filter ?
try removing the fuel injector and see if its spraying fuel when you thumb the starter.

sometimes continuously trying to start the bike might flood the engine and prevent it from starting.. remove spark plug and hit some compressed air into the cylinder and let the fuel come back out and evaporate.

and then the valves.. like i mentioned earlier, if the valves aren't closing properly i.e. either due to bad timing, or too less of valve clearance then the bike will not start due to lack of compression. i suspect this could most likely be the cause.

a bike basically requires these 4 (and in the right quantity at the right time) to fire up:
-air
-fuel
-compression (which many forget, on a 4 stroke bad compression fix could be as simple as getting the valves back in spec... many think the fault is worn bore/piston rings which is not always the case)
-spark.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Going by the pic you've posted earlier of the state of the fuel! I highly doubt your throttle body and injectors are choked! I mean I do agree there is fine fuel filter after the fuel pump outlet from the tank, but it can only do so much if with this level contamination. Along with bike being parked for so long.

One way to solve this, get a compression test done, are you hitting 8psi-12psi+ compression and do you have current through the Spark Plug? then it's 90% guaranteed to choked injector and throttle body.

If you do find the injectors choked, remove them and the best way to clean it is take a 9V HW battery, couple it with injector to turn it to ON state and valves open up, spray some injector cleaner in reverse from outlet to inlet direction. There are ton of videos on YT showing on how to do it

Re: KTM Duke 390 - Ownership Reviews and Experiences

Checked fuel pressure? Check your fuel lines, and check the injectors if they're spraying fuel. Remove the injector and check. If all these parameters are fine and still the bike doesn't start, I'd strongly suspect valve timing. Keep trying and keep your observations posted.

Caution is the byword now-do give a serious thought to whether you will continue to invest time,money, emotions into the machine or decide to let it go after getting it running-KTM's can be a perplexing nightmare to sort if/when they start to go bad.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Checked all the fuses individually, all of em look fine. Checked the spark plug as well, it is giving spark. Unable to find the issue [emoji3525]

Re: KTM Duke 390 - Ownership Reviews and Experiences

Start off with checking the fuses of the fuel pump and all the fuses in the fuse box. If you have a bust fuse, the bike won't fire up. Secondly, unless you haven't changed your oil for 15 years, the oil won't turn to jelly and in which case the engine won't even spin even if the starter motor tries to, and at the least, the bike will fire up. We have a bike that doesn't fire, so it can be either bad fuel, no spark or no fuel pump pressure, as simple as that. Start off by inspecting your fuses first, then check if you have spark coming at the spark plug and that the plug cap is properly inserted and locked to the spark plug and with these two things checked and ticked off, check the fuel line or proper fuel feed to the injectors. Good luck. Keep your observations posed.

Cheers!
