Noise opinion

Hello, shy of 200 miles on my bike, I am more concerned with a noise I hear when the bike is revving in any gear and when reaching just 4k rpm. The noise sounds like a rattle or muffled knock. I tried to capture it on video with my phone but when just revving the bike it is not as obvious. I am wondering if anyone can offer an opinion. I have read around that some versions have had issues with the cam chain tensioner which could be the cause of what I hear but that would mean a potential shift in timing which I don't perceive from the bike. Other than that, this bike rides very well and has, what I perceive, is adequate power. Its first service is coming up, I was considering doing it myself but now I feel that I should take it to the dealer. The dealer nearest me is over 100 miles away so it is not very simple to bring them the bike. The bike runs well otherwise. No stalling or sputtering or anything like that. Just that noise.
Thanks in advance for any opinions offered. Ride on!

It could be a number of things. The soft clicking/ticking type noise in the background on your video sounds like the valves/tappets and is not out of the ordinary. So don't worry about that too much. That aside, is the sound more prominent when riding the bike? If so check the headlight for rattle when riding (that's a fairly common issue and very easily fixed). Listen to the sound carefully and try to decide if it's more a plastic on metal rattle or a metal on metal rattle. It could be a loose nut on the exhaust header pipe. Best go through the bike and check all the nuts and bolts are tightened up. It's most likely something and nothing, but to be on the safe side raise it with the dealers at the first service interval.

On my Himalayan I'm pretty sure the rattle is/was coming from the blue plastic fuel sensor connector slapping against the underside of that tank and/or against the frame when riding. Placing some foam between the connector and the tank seems to have alleviated the issue significantly.

i can't hear any thing unusual. It's not the same noise as discussed here? http://royalenfieldowners.com/index.php?threads/ticking-noise-over-3000rpm-when-riding.223/page-2#post-2248

The engine has some sort of resonance frequency around 4000rpm that is annoying but will smooth out quite a bit with more miles.
Hello and thanks for the reply. I totally forgot that that post existed and that I had actually posted on it. Had I remembered, I would have posted this there as well. If an admin reads this, please move it to that other post.

Quite frankly, I think it is similar. That gargle whatever sounding thing. I think I will try to record it as he did, riding.

Thank you.

Thank you. I am hoping for good weather tomorrow to take it for another spin and try to isolate it more. Thanks again.

I have a rattle noise coming from my engine, after many many many conversions it seems *some* people have this issue and is completely ignored by RE (even previous generations have it). I even talked to the dealer about it and the basically brushed me off because of the design of the bike. Ignoring one very blatant issue: Not everybody has this problem.

For me it's louder under a load, I can hear it through my helmet and ear plugs.

Though listening to yours I don't quiet hear it but I does sound like maybe your exhaust is loose, mine both the nuts were loose and I could push the exhaust in slightly. DON"T over tighten them, they used some very, very soft metal on the plate and it bends easily.

But I agree, if you are comfortable with wrenching it go over it. If it can come lose somebody has had it make a rattle noise.

Hi, mine does it more pronounced under load as well. It actually sounds just like the bike in the link that @CarstenB provided a few posts above. I will check the exhaust as you mention. It may be what it is. It is too high on the engine as I perceive it for me to zero in on anything internal to the engine. We will see. Good luck .

Mine has a rattle to it as well. I did correct the headlight rattle with some strips of electrical tape on the inside rim of the headlight bucket. As for the engine, it is what it is. It's not as smooth and refined as other thumpers, but it's reliable. I've ridden 330 miles in one day on mixed road types and the Himalayan did great.

Funny, after my first service, I went for a ride and the bike felt wonderful with very little noise if any. Reminded me of an old BMWks1200 I had. Yesterday, the noise was back. Oh well, it feels like it is running well. I will inquire with the dealership next time I can haul it there.

Sounds like a normal long stroke rocker arm air cooled single to me.

Hi, I know this is an older post but I was hoping you might have some updated info. I have EXACTLY the same issue with my 2022 Himalayan. Everything is fine until I hit about 3700 RPM then it

Hello! I know this is an older post but I was hoping you might have an update on this issue. My 2022 Himalayan does the exact same thing. Everything is fine until 3700 RPM then, from the top end I can hear a knocking sound (almost like bad gas or a timing issue) as it revs up. But here's the thing; if you listen to the exhaust note it sounds fine. It doesn't lose power, it's responsive and rides fine. The noise is most pronounced when I listen directly above the gas tank. I've got about 800 miles on it and it's done it from day one and isn't getting better. First service was completed, exhaust valve good and only a minor adjustment to the intake valve. Changed to an iridium plug but that didn't help.

It's most noticeable in 2nd, 3rd and 4th gears and can be heard a little in 5th. Revving the bike in neutral won't reproduce the sound. Typically happens more noticeably when it's *not* under a heavy load (for instance, it's far less pronounced [or nonexistent] when going uphill with a lot of weight on the bike). But if you're just cruising around and stretch out second or third gear, you can really hear it.

I've read about the harmonics but this seems different to me...but I'm not an expert. The fact that it doesn't lose power and has a clean exhaust note is what has me truly confused. That and the fact that revving in neutral is no problem. Many other threads point to various idiosyncrasies that smooth out as the bike breaks in (runs in). Was this your experience? Did it finally go away?

Any thoughts or opinions would be welcome.

My local one man shop owner is an real actual time served and qualified ex race mechanic and can usually tell you the problem/ source before you have switched the motor off.
So, if you can find a local one man mechanic, small family dealer or whatever it will take them seconds to identify the source of the noise.
Main dealers employ whoever walks in from the street, they might have one or two actual mechanics but they will be to busy doing the hard, well paying stuff to come out and give free diagnostics, unlike a small shop who depends on making friends for life and their repeat business.
Don't get obsessed with warranties , sometimes the cost of forcing someone to do something free is more than paying someone to do it properly.
