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.

Re: KTM Duke 390 - Ownership Reviews and Experiences

does the bike 'crank' or is it just silent as you try to start it ? Any clicking noise ?
check all fuses.
could also be a bad starter relay, if it is not cranking at all. Or a bad starter motor.
also check all fuses.. and i am assuming the fuel pump, its connections were done properly.
did you check if the spark plug is indeed producing a spark by grounding it to chassis ? a bad ignition coil might be responsible for no spark

If it does crank, then i would suspect the valves are not closing properly and needs to be looked in to.

Vacuum will read around 11 at idling iirc. but in your case the engine doesn't fire up.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Update : Installed new fuel pump, new spark plug, new air filter & charged battery. Still bike won't start I've screen recorded the torque app readings while cranking the bike. Can anyone make out what's wrong by reading the outputs ? Does the vaccum no. looks fishy ? Posting a youtube link.



Also, is it possible that bike is not starting because engine oil might have turned into goo? Was planning to flush the engine oil once the bike starts.

Re: KTM Duke 390 - Ownership Reviews and Experiences

Understandable for the parts given the current situation, but They should also have online sales. I managed to get some parts offline, some ns 200 parts, skf wheel bearings (btw looks n feels better than stock ones), etc outside.


I need to get the spring compressed somewhere thats about it.. im good to go.

Good luck with your build!

My build is here

Re: KTM Duke 390 - Ownership Reviews and Experiences

You can confirm 100% on this, KTM has stopped over the counter sales for most major parts(unless you know friend someone within the SVC or big have influence), my 390 is waiting for parts for a full top rebuild from almost 20days now.
Parts are coming in one by one slowly based on back-order and advance payment only directly from Pune and directly being used up on the bikes which are waiting in SVC from months for parts due to lock-down.

The info I got from Head of spares for Bangalore was Bajaj/KTM factory in Pune is operating only at 30-40% employees capacity as cases are reaching 3L in Maharashtra, so expect this parts and spares issue to continue for some more months.

Yes, if you're using the mobile app, it happens to some users. Try resizing the picture size to less than 1 MB and try.

Re: KTM Duke 390 - Ownership Reviews and Experiences

I have installed a Akrapovic Replica on my Duke 390. It is not a full system, only the end can is changed. Below is the video of the same with dB Killer, use your headphones :




PS : I am not able to attach image here, xBhp app is showing an error "You donot have permission to perform this action". Any ideas?

Re: KTM Duke 390 - Ownership Reviews and Experiences

Your only bet is to look at the same in a junkyard or used parts dealers, or a new one. It takes time, but you can find it if you're lucky.

Re: KTM Duke 390 - Ownership Reviews and Experiences

wheel bearings you can buy outside the svc at a local spares store or maybe from the svc of another manufacturer. what you need to find is the bearing number, its going to be something like 6301, 6302. iirc i think the front one is two 6202 and rear has 6302 and 6202 .
once you have that information, or an old bearing u can take it and buy one outside (nbc or skf bearings, or oem from another vehicle that uses the same bearing)

search for the parts catalogue on google for further comparison to find which bearings will fit your wheel
