Re: KTM RC 390 Ownership Experience

Its very low, even in worst case i got 17-18.
You can check if there is any white or dark black smoke is coming or not that will indicate fuel is not getting burned properly.

Check with svc for any errors on ecu. Maybe o2 sensor went bad.

Maybe you can give a try at different petrol pump to check if fuel quality issue is there.

Re: KTM RC 390 Ownership Experience

No white or dark black smoke either,
I always put speed and last month I did add adon p as mileage was decreasing.
Will take it to SVC after checking it again from tank to tank method.
Thank you.

Re: KTM RC 390 Ownership Experience

That's a forum record to say the least. Something's definitely not right here. Can you share some details about your bike? Kays clocked, and modifications done to the engine et cetera?

What got my attention here is this, when accelerating and slowing down. A chain tightens and loosens at these exact scenarios. I suspect a chain fault here or a faulty front sprocket. To my observation skills, when I listened to the sound clip, the final hard blow where the bike jerks and then gains composure would mean, either the chain is slipping so bad that it jumps off the sprocket, grabs which definitely would cause such kinda friction sounds. That's one.

Chains make different sounds when they're loaded, not lubed and not slacked. If you can, jack up your bike, engage your bike in gear and observe for any sounds or creaks. (discretion advised) Chain normally have some friction sound associated to them, a constant mild "wizzzz" during riding which is perfectly normal. Secondly, an unlubed and improperly slacked chain would jump around when rotating and rubbing against the pads and make sounds even worse. This sound is what gets people irked.

Top Tip!

1. Clean the chain area, both front and rear thoroughly.
2. Make sure the chain is provided with the right slack, a teeny weeny bit tighter chain won't do any harm.
3. Make sure the chain is, again, thoroughly lubed.
4. Keep your observations posted.

Yeah..
Bike is stock, I've done about 13000kms and it's around 2.5 years old.
I take it out like twice or thrice a week for around 10-15 km run and monthly once 300kms ride.
No modifications to the bike.
I put only extra premium fuel to the bike.

Re: KTM RC 390 Ownership Experience

I got a second opinion from another KTM SVC here in Hyderabad. The person there instantly noticed that chain has uneven slack being loose at some point and tight on other. He took video and photos of my bike to show it to senior person. I was told that chain sprocket assembly will be replaced for this. When I asked that this being manufacturing defect, should be replaced under warranty, the person said that most probably it will be under warranty.
Now my question is that since my bike is not even a month old and done only 520 km on the odo, this should replacement should be done under warranty right? I did not like the sound of "most probably".

When the bike is on paddock stand and in 1st gear, the chain rotation is somewhat irregular at some points where the chain is tight and it makes a little sound like its hitting something.

Re: KTM RC 390 Ownership Experience

The chain and sprocket kit will be replaced under warranty. As a note, I'd suggest you to keep all the records as evidence just in case. Thirdly, with respect to the new bike thing, why me, why my bike, well it happens. Chains don't wear uniformly and as I suggested in my earlier post, it's mostly caused by a faulty chain wherein the chain is warped to an angle or the alignment of the front to the rear sprocket is off. Get your sprocket replaced, make sure they are lubed and set the slack right. Do keep your observations posted.

Re: KTM RC 390 Ownership Experience

Would be wonderful if the part was replaced under warranty but as per the owners manual warranty does not apply for consumables, so do double check.

Re: KTM RC 390 Ownership Experience

"Thirdly, with respect to the new bike thing, why me, why my bike, well it happens." I am aware of this as technically bajaj makes these KTM bikes. I have UGIV pulsar 150 dtsi with me in which I have seen problems which made everyone clueless. There were numerous issues with that bike from the start but nothing that was not fixed by the SVC [Even though they solve small problems by directly replacing all associated part]. But those few things aside, It is one hell of a ride. Brings smile to my face whenever I ride it.

These things aside, the build quality has certainly improved and even with these issues, I find it a great value for money option.

I will keep things posted when issue gets resolved with my KTM.

----consecutive posts auto-merged-----

True but its not even complete 4 weeks and chain sprocket issue has come up. I guess I have a fairly solid ground to fight for these to be replaced under warranty if it comes down to that. Lets see how things go.

Re: KTM RC 390 Ownership Experience

My Speedo cable on the ZMA snapped a very short while after purchase, had to pay to get it replaced.

Do share your experience, would love to see how Bajaj would handle the issue.

Re: KTM RC 390 Ownership Experience

should be under warranty, and mostly will be done under warranty.
on your part too, just shoot an email to [email protected] appraising them of this situation politely.
and which svc in hyderabad did you visit ?

Re: KTM RC 390 Ownership Experience

It's these little aspects of motorcycle(ing) that makes one closer to his/her machine. Nevertheless, we'd like to hear more about the replacement carried on your end and do keep us posted. What I'd like you to do is, a prognosis if I may. An inspection of the older component by the SVC team and you, especially the sprockets F and R for any warpage and the chain for any kinks and/or frozen links, the overall gamut, if you can would be great.

Re: KTM RC 390 Ownership Experience

Update:

Both front oil seals of forks were replaced in front of me properly.
They worked well for 3-4 weeks only. And now again one of the fork started leaking again.
So looks like it's time for replacement.

Should I replace only tube or whole fork?

Re: KTM RC 390 Ownership Experience

As s1d has already informed you in his earlier post, before replacing the tube or anything first did you check if there is any scratches, groves on the current tube or if the tube is slightly?

Also, suggest you to replace the seals from the newer 2017 Duke 390 which are much improved and is sourced from a different vendor.

Re: KTM RC 390 Ownership Experience

Did u check the fork tube..every inch of it carefully for any scratches/pitting ? was it thoroughly cleaned and installed.
sometimes improper installation of the seals can also cause premature failure.

usually just the fork stanchion tubes can be replaced. how much did they quote for the tube ? the entire set is pretty expensive.

Re: KTM RC 390 Ownership Experience

Seals going bust repeatedly isn't something common. IIRC, one fork leg costs close to 8.5k-ish and both 200 and 390 have the same leg. If you can source a fork set from the used parts market, you could save some. Dust, and scoring or fine pitting on the fork slider would mean seals going bust often. It's very hard to diagnose without seeing the slider and examining it carefully. Any idea the amount of oil they poured in? 450 ML is the right ballpark, too much and the seals would go bust soon.
