New BS4 R3 launched at 3.48 ex showroom. Gets Dual channel ABS and Metzelers. I guess you should get it eyes closed

Can somebody tell me the preferred battery for D390. Mine is taking multiple efforts to crank. I guess I have to replace the old battery.

The official recommended one is Excide.

Exide is the OE supplier to the KTM's. I have replaced mine a couple of months ago from Mekhri circle SVC for 2106 INR. It is half an hour job with the acid being added to the battery and left for sometime before it is mounted onto the bike.



This is the stock battery which lasted around 3 years and 8 months.

I have replaced my 2014 battery to EXIDE XLTZ-9 8 Ah for 2000 rs

Not sure about placement of coolant tank in Duke 390, but in my RC the coolant tank is prominent and easily visible, with the bright green coolant level prominently showing.

Has anyone tried lowering the footpegs on the 390? Mine is lifted at front by about 2 inches using fork spacers and I have clearance to drop the pegs by around 30mm.

The stock battery that comes with the bike is of black color and Exide sourced, the OE supplier of the battery. Recently, the Dukes from the factory come from RED color battery, so it's just a matter of color.

Secondly, you also have SF Sonic MK1440-TZ9 (8 Ah) that is available for Duke as a replacement to Exide. But, if you're skeptical about the longevity, stick to the stock FEXO-ETZ 9 (8ah) aka XLTZ-9

Cheers!

Notice that many have faced issues in stalling when pulling the clutch (to downshift) when slowing down from higher rpm/speed and of course the famous JG_1.7.3 issue.

The 'famous' 15 minute idle reset procedure. This resets the adaptive base values of the ECU. It won't transform the bike but it can make a worthwhile improvement. It is very important that the engine is stone cold. One or two hours after riding is not enough! Do this after the bike has been off for a full night or day. Start the engine and let it idle for 15 minutes without touching anything. After 15 minutes, switch the engine off with the ignition key. Done. During this procedure you won't see or hear anything happening besides the idling and (probably) the fan. Don't worry, the reset is done. Besides after certain maintenance or parts replacement, you could consider doing it twice a year with the turning of the seasons. A reset for the colder autumn & winter period and one time for warmer conditions during spring & summer. This is not mandatory or needed and don't expect miracles.

So some queries:

• Has anyone tried the 15 minute ECU reset? If yes, was there any difference?
• Did any of you bump the preload to its highest setting?
• In the city, what would be the ideal tire pressure riding solo. Manual says 29 psi. What does experience say?

Dear BHPians,

I own a Sep 2016 Duke390. It has been everyday delight to ride this machine. So far, I have not felt any problems in my 18300 km ownership. Recently, I had my ride serviced, it was first paid service. After the service I discovered that coolant level has been going down, I got it topped couple of times but the level keeps going down. Water pump and water pump seal was changed as part of first trobleshooting session recently. Still the problem persists. After a ride of approx 150 km the level went down by 5 to 6 mm. I nèed to go for another round of diagnosis now. From my side,
I have gone through some of the earlier discussions on this forum and checked couple of points.

1. Engine oil colour - Got it checked by technician who mentioned the colour is ok and do not see any engine oil - coolant mix problem. He checked oil colour at the drainage plug point.

2. Frothing - I dont see any milky / white frothing from the oil observing glass. However, I do see dark brown froth inmediately after ride but it disappears when the bike is stand still for 15 seconds with engine running. Technician told me that, it could be because of water/water vapour but not coolant. I have attached a picture of the froth.

3. Coolant leakage - I tried to check if there are any signs of visible coolant leakage but could not find any.

4. Burnt coolant - There is no sweet smell of burnt coolant.

5. Exhaust check - Checked exhaust for any oil traces but it is clean and dry. Just 'traces' of black soot.

6. Radiator grill - I have attached a pic of radiator grill. Technician did not mention any problem with the grill so far but I do see linings bent. Can this be the cause of coolant disappearing?

There are 2 more points that I want to mention related to the last paid service -

1. Some oil seepage was there from the top of the engine. Some bolt was tightened to fix this. The oil seepage thing was fixed but I felt some sort of 'tighness' in the engine after this.

2. When the bike was started for the first time after the wash, there was 'white smoke' from exhaust. It disappeared when the service supervisor revved the engine. I have checked for white smoke again during the cold start but I do not see any smoke, white or blue.

Need some expert suggestion on what should I do next as Service centre guys are in trial and error mode.

Did you go to Orange KTM at Baner?
1. The seepage from engine head does happen. And the solution is to tighten the bolts.
2. Was the smoke coming from inside the exhaust or from outside? For some absolute brain dead reason, they washed my bikes engine, silencer, etc with diesel! And white smoke started coming when the engine got hot.

Sorry I cant help you with coolant leakage. Have you tried the SVC at Nal Stop?

I went to Wagholi service centre for the servicing. They did tighten the bolt and there is no seepage since then. White smoke problem happened only once at the service centre when the bike was started after wash. It never happened again.

Hey, I know a little about this coolant going low issue. Tell me one thing, as part of service was a Coolant Flush done?

If YES, then coolant level drop shall happen as the air gets trapped in the lines when a Coolant Flush was done, it takes time for the air to get released.

Do you know how many liters of Coolant was refilled? and How much is the bike Coolant tank capacity? You can do a quick check and find the delta coolant quantity to be refilled (probably over few days)
Wait for a week and always check the coolant level when the bike is in cold state, like first thing before you start the bike in the morning.

Thanks 90Horse, coolant flush was done and finally the coolant was filled to half level between min-max. I have ridden for about 150 km since then and coolant level is now at minimum mark when I checked in morning after 2 days. I will top it up again once before going to service centre.

I borrowed a friend's 390 recently, and the bike was straight up spitting coolant all over the right side of the bike (and my leg). There was a leakage in the line supplying the engine and I heard it was a recurring issue. I can see how this info isn't a huge value add to your problem, but perhaps voicing it will catch the attention of other owners that are facing recurring issues and a solution can be found - I checked out of this 390 scene a while back when I sold mine, and haven't kept up with recent developments.
