Re: 2017 Duke 390 Owners Reviews and Experiences

HI All,

This might not be exact forum for this but hope I would get some answers.
I have an old MT Axxis helmet which was good enough for CBR now with Duke 390 it makes a lot of noise beyond 60 kmph and also it has become very old and loose too.
I'm in market for new one all the new MT helmets seem to have same noise problem as many owners have pointed out not sure its problem for them only or its universal.
My budget is around 10K at max there are few I have shortlisted like Bell Qualifier and few HJC, MT helmets the reason being I can go to a store and try them out but no one I know have used them so not sure how they're in long term or in high speeds.

What helmets you guys are using ? Which one do you recommend ?

Thanks VJ.

Will ask them to replace the plug.

The bike is under warranty and would push for CCT replacement.

Re: 2017 Duke 390 Owners Reviews and Experiences

Replace the spark plug, don't clean it. CCT would cost 250~ approx and if you're under warranty, and if you can push for it, they'd replace that along, if found faulty.

Cheers!

Hi VJ,

It’s clocked 14.5 K. The spark plug has seen 6K kms since my penultimate service. Will try cleaning this.

Any idea on much CCT would cost? In the event that it is faulty would ask the SVC to replace this.

Re: 2017 Duke 390 Owners Reviews and Experiences

How much has it clocked? The tick tick sound can be due to CCT and offset valve clearances. Intermittent tick tick sounds would mean faulty CCT. Secondly, the erratic idle can be due to a lot of factors, dirty air filter, gummed up throttle body, blocked fuel filter, offset valve clearances, dirty spark plug and or idle stepper motor issues. I'd suggest you start off cleaning/replacing your spark plug, air filter and then try using Shell V power fuel and see if it helps. If the issue still persists, then you can consider inspecting your cam chain tensioner and valve clearances

Keep your observations posted.

Cheers!

Hi John,

Thanks for your response!

I’ve tried the dirty ECU remap by idling the bike for 15 mins after a significant cool down. It sort of worked temporarily on the idling and switching off part before going back to bad behaviour. Will check with SVC on the ECU update.

I would also ask them to look at the Valve shim while there. Planning to take it in March. Would keep you posted!

Re: 2017 Duke 390 Owners Reviews and Experiences

The "Tic" sound could mean shim adjustment. How much has your bike run?

Idling and shutting off was rectified with an ECU update. I don't recall the version, but I had the same issue. If your ECU has the latest update, try reflashing and updating it again.

Hope this helps! Please keep us posted on updates.

EDIT: Just read that your bike has run 14.6K kms. It's most probably the ECU. If the SVC doesn't agree to a flash/update, try hard resetting the ECU by removing the battery wires (google for detailed info). The ECU should auto adjust by itself IIRC.

Re: 2017 Duke 390 Owners Reviews and Experiences

Hi,

Thank you for your response!

The spark plug was changed in the penultimate service as well as the oil and air filter. It still didn’t help as the problem continued.

I don’t want to suspect the fuel pump at this stage as the bike has been in constant use and has never gone even near dry. It’s run 14.6K kms. Should I worry about this?

Re: 2017 Duke 390 Owners Reviews and Experiences

Injector cleaning/clogged air filter/dirty air filter/dirty spark plug could be one of the reasons.

Re: 2017 Duke 390 Owners Reviews and Experiences

Hello,

I own a 2018 Duke 390 and seem two have two peculiar problems for which the SVC haven’t responded that well in the past two services.

Problem 1: An audible tick tick sound comes out of the front of the bike (around the engine area) when I ride it. This doesn’t come always, but is persistent when it does.

Problem 2: The idling is erratic and more often than not, the ignition gets cut during the first try. The bike works without getting off after a bit of revving and after the second or third try.

Could you help me out with this. Thanks in advance!

Re: 2017 Duke 390 Owners Reviews and Experiences

Yes it is not just a rumor I have seen the launch videos too, they indeed get the bi-directional quickshifter along with BS6 engine. And they launched new matte grey color along white with new stickers but unfortunately the white comes with black alloys and looks very bland atleast in vidoes matte grey looks really cool unfortunately they discontinued the orange color which most KTM people like.
Coming to can quickshifter be fitted to 2017+ model ? only service guys can confirm but from KTM's past I remember the first gen Duke 390 came it had normal clutch but later was given option to upgrade to slipper clutch at extra cost so finger crossed.

Re: 2017 Duke 390 Owners Reviews and Experiences

UPDATE:
It's been 11 months since the coolant swap, the temp gauge has not gone above the half way mark at all. The bike has been ridden 95% within the city, peak traffic hours and spends a good 2.5 hours in traffic, 5 days a week. Engine showed signs of roughness, and I decided to drain, flush and replace coolant again. Went with the same CBR250 premix available at all Honda OTC spares. Been 24 hours since coolant swap and the bike is back to it's original smoothness. Old coolant seemed darker than a fresh bottle, but did not see any separation as seen in the initial Inugel case. Seemed it would still go on for a couple of months. Volume has been a hit and miss, manual states 1.2 litres, it barely took 1 litre last time, this time it gulped a bit over 1.2

Overall happy with performance, and small joys of bringing the roughness of the engine down. Keeping tabs on gauge readings.

Messed up the drain bolt by over tightening it with a rachet. The bolt sheared and broke. Fortunately was able to get the broken bolt out without any damage to the thread or pump casing. Mental reminder to be gentle from here on with engine bolts

Re: 2017 Duke 390 Owners Reviews and Experiences

You should be able to get done if you enough money hand.
New ECU, Wiring harness, Quickshifter sensor, New gear lever and you should be good to go!

Re: 2017 Duke 390 Owners Reviews and Experiences

Power Drift have confirmed on their Instagram page of the new one having bi-directional QS and black subframe, but let's wait for the official word. It should be swappable given the familiarities between the both, but let's take it with a pinch of salt right now.

Cheers!

Re: 2017 Duke 390 Owners Reviews and Experiences

Hello fellow xbhpians. As the rumours making rounds about bs6 duke 390 getting a bi directional quick shifter. Do you think we can fit the quick shifter on our 2017+ duke 390s.
