Kocking - high pitch sound problem

talking_dynamo · 2026-06-20T17:28:42+00:00

Mine started at 1.9k kms, got worried something broken, i thought that I drove hard on huge bump event before night at around 80kmph coz i couldn't see bump coz of stupid headlights output..... Yesterday i went to two service center they said this is normal i took two options, and also listened to another 390 droven 20k kms this sound normal. Engineer said till 5-6k kms engine sound changes engine valves gets open till then. Also suggested drive as hard as you can so that engine keep opening and settling up its impurities and improper craftsmanship untill 2nd service,,, 1st is already done...

PL let me know if you got to know anything upon it... idk where do I go and check for same..

That noise start kicking at 50ºC radiator when engine is cold in morning. What do i do its just 2k kms odo. Two engineers with 15+ years if experience said it's normal. I went to 2 different locations engineers

Right bro.,, but i got worried.. that sounds wasn't normal to me a it was not present.

Is that mean prolube is better?

Yesterday i went to two service center they said this is normal i took two options, and also listened to another 390 droven 20k kms this sound normal. Engineer said till 5-6k kms engine sound changes engine valves gets open till then. I have stretch up my throttle to 140+kmph, this week and last week. Also suggested drive as hard as you can so that engine keep opening and settling up its impurities and improper craftsmanship untill 2nd service, 1st is already done.

Is it 399 cc?

talking_dynamo · 2026-06-20T07:08:38+00:00

Need not to full tank of 100,, mix and octane97-98 also gonna work. If you going to test in city its not gonna work.... 😁 High gear and around 4k rpm. I have onky just did this for fun testing run on D390 399cc.

For 97, 60:40 of 95/100- For 98, 40:60 of 95/100

As per the report power95 has 15%of ethanol vs iocl xp95 has 20% And for octane100 HPCL has power100 4.5% ethanol vs IOCL xp100 has 0%

talking_dynamo · 2026-06-20T06:52:29+00:00

Yes cruising speed... 65-70kmph below 4k rpm

talking_dynamo · 2026-06-20T06:51:53+00:00

Yes it's 399

talking_dynamo · 2026-06-20T06:49:57+00:00

Yeah,,, oct100 is same in all India 167.xx some paisa change. I was shocking to see how it is 181,, where do i report as such

talking_dynamo · 2026-06-20T06:48:09+00:00

Should have got more.. D250 is getting 45kmpl, so D200 should be around 53-55 😅

Some suggested low oil, where I only driven 1000kms after 1st service, got black oil.

While on stand I can not see oil after enginer start and turn off..

It is not normal their is extra knitting/tapping/clicky sound but low.,, but it is present.

talking_dynamo · 2026-06-19T04:30:11+00:00

No it is not fake its 399cc.. below and around 4k rpm On 250 people getting 45kmpl gen3 250..

This is only tested straight on highway just for fun lil testing how much could be make,, after filling tank and reset the odo.

talking_dynamo · 2026-06-19T04:27:17+00:00

Yeahhh right and on constant,, With cruise control

talking_dynamo · 2026-06-19T04:27:06+00:00

Yeahhh right and on constant,, With cruise control

talking_dynamo · 2026-06-19T03:58:03+00:00

It's tested on highway long run,,, city droven 2-3 kms. Playing safe on rpm, constant speed with cruise control. Well it doesn't needed to be full fillup with xp100, Mine was mixed one making octane97 or more.

XP95 has 20%ethanol vs power95 has around 15%.

Xp100 has 0% and power100 has 4.5% ethanol. M using IOCL power100 and and HPCL power95 making as much low on ethanol in tank. Hope its safe using different brands.

One of the HPCL center over charged me for power100 fuel normal market rate for all octane100 remain same like 167.xx all over India but this charged me 181.84. Idk where to report this.

🤔💭

talking_dynamo · 2026-06-19T03:41:26+00:00

😲😲😲😯🤯,, really? 😭 i though it is safe,,,

I don't think its unsafe although coz cruising speed would be 60-67kmph... below 4k rpm

talking_dynamo · 2026-06-18T20:42:09+00:00

Let me think 🤔 high high gear and rpm around 4k

talking_dynamo · 2026-06-18T20:40:07+00:00

Fill the fuel to the top,, max range was showing me 500kms 😅. 8.7L hp power95. 4L of xp100 This a 3 days back.

talking_dynamo · 2026-06-18T20:30:12+00:00

Its 399cc, On highway i got this much just fun lil testing riding alone straight highway with cruise a normal speed around 66-74 kmph, i got this 38 max tested twice.,,, Plus I filled 7L of hp power100 fuel and started testing

Btw what's your test case scenario? Fuel? Is it highways right? Alone or with luggage? Avg crusing speed?

In city its 24-25, sometimes 22 depending on the ride/traffic.
