Re: KTM RC 390 Ownership Experience
I did show the bike to the SVC over the weekend. The mechanic told me pretty much the same, he suggested cleaning the throttle body and changing the idle stepper motor if necessary. He called me the next day and said he'd cleaned the throttle body but didn't change the idle motor since it was working fine. So I reach the workshop and take the bike for a test ride and found the issue wasn't fixed at all. I should also note that the engine starts normally during a cold start, it's only when it gets warm say over 4 bars that the problem appears. Also, it does seem to get worse by the time the engine reaches full operating temp. And once hot the doesn't start in the first few attempts. Interestingly, I am not able to control the stall when stuck in traffic using the throttle (i am a skilled rider), say by keeping the throttle part open, only rapid blipping seems to save it from stalling for a while. Anyway, they got an idle stepper motor from a neighboring workshop but tell me that it doesn't fit my 2016 rc390. And today when i went to check with the mechanic he tells me that there's something wrong with some sensor and the whole throttle body needs to be replaced. At this point i got more money than time, so i was ready to get it changed but they don't have it in stock and the waiting time would be 10 days. So for the second time i rode my bike home through crazy traffic with the bike constantly shutting off. Problem is this my only means of commute and besides i need to ride a bike daily otherwise i get withdrawal symptoms!
My bike's done 22.5k km. Just a few days back i got the whole clutch basket changed (only the friction plates and springs needed to be changed but they didn't have springs in stock) for Rs 10k including service. I am now wondering if it's worth spending more time & mon eyspending on this bike (the airbox is cracking again) instead of upgrading to a more reliable bike. In terms of handling and performance this bike has no match anything below 10lac but it's just a shame with the parts and quality issues. Well one can argue that the parts are cheap but what does it matter if the mechanics are incompetent. Getting any engine work would be a throw of the dice and chances are you would be left with a treatment worse than the ailment as happened with my R15 rebuild

49 as you've suggested iterates to faulty idle stepper motor. This part is available as a spare and can be replaced for a faulty one, costs approx 1500 ~. How much has your motorcycle clocked? A high mileage bike can use a thorough throttle body cleaning, which clears the clutter in the throttle body for a smooth operation and brings back the old crisp acceleration.
Check your idle stepper motor at your nearest SVC. This motor controls the idle, a faulty one would mean, intermittent unwarranted stalls, sometimes it even stalls during high speed riding, when the throttle is cut. A classic example is when you coast downhill or uphill and pull in the clutch, the motorcycle engine shuts off.
Get it replaced and your throttle body cleaned while changing the stepper motor.
Keep your observations posted.
Cheers!
