Re: KTM Duke 390 - Ownership Reviews and Experiences

Vibrations are from engine and I can feel near the tank area as well.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Your question is too generic, it depends if the vibrations are from the engine or chassis/drive train or other plastic body parts and fitting.
A more in detail description on the same would be helpful to get some idea

Re: KTM Duke 390 - Ownership Reviews and Experiences

Hi Guys,
I need some advice.
Recently I got an used ktm duke 390 (2015 model done 25k kms) . I feel bike is vibrations are more.
I heard about Liqui Moly kit.Does it help to reduce vibrations? .any other tips to reduce vibrations like engine additives etc.
Thanks in advance.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Hey folks,
Has anyone here considered retro-fitting the exhaust from the 390 Adventure onto an old-gen Duke? I'm considering this since I want to quieten down the bike and loved the exhaust note on the 390 Adv.
Opinions please?

P.S. I had asked about retro-fitting the exhaust from the new 390 about 2 years ago. Please don't mind me asking the same question again.

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.

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.

Cheers!
