"Pop" sound from engine area

Hi, I own a 2019 650XA with a little over 4k km. Everything was going well with the new bike but recently this has been happening almost always.
After I either stop suddenly or decelerate to a stop, the first time I accelerate, the motorcycle pops (like a small backfire) but from the engine area. It runs normal (I think) after that but I feel like it's getting more and more frequent.

When it started it was due to a hard braking or deceleration, now if I stop normally it will still "pop".

Anyone has any Idea what it could be or if it's normal? This is my first motorcycle so I might be overreacting.

Thank you in advance!

(I leave a picture of her to brighten your day)

Popping on decel is normal. Popping from the engine upon restart is not. Take it to the dealer before the warranty expires.

It doesn't sound normal to me. There are several people on this forum that can probably tell you exactly what is wrong and how to fix it, but if it was my bike I would still have it fixed under the warranty. Because you say the problem is getting worse,I would recommend not riding it anymore until you get it checked out by an authorized dealer.
My 2 cents

potentially loose bolts connecting engine with exhaust?

I'm interested in what you find out about this issue, it sounds similar to things I've noticed on mine. Occasionally if I coast holding the clutch, when I get back on the throttle to match revs for whatever gear I'm now in, I get that little pop/backfire. The bike also stalls occasionally the very first time I start moving on some mornings, not sure if that's related...

My issue never got more frequent and I figured it'd be a nightmare troubleshooting it. The dealership said they'd have to charge me if it wasn't found, but then I could be covered beyond the warranty if it ever was... With how infrequent it is I never had it checked out and my warranty just expired.

Best of luck, and I hope we can get some useful information on what seems to be a currently unknown issue.

Popping on de-acceleration and throttle opening is normally associated with a leaking exhaust system as cold, oxygen rich air is drawn into the exhaust where it mixes with the super hot exhaust plus a little unburnt fuel.

Since the day I posted this the issue has been gone.
The only factor that changed since then is the weather which is hotter again. So I'm going to wait till the temperature drops again and see if it comes back, if it does I'll be able to reproduce the problem when I take her to the dealership.

I'll be sure to get back to you with my findings.

When I first got my bike last year the dealership told me to bring it back after 2 weeks to have all the hardware checked
and retightened this included the exhaust headers as well. Which I did and everything has been fine.

did you do a similar thing ? Did the dealer you purchased from say anything about this ?

I did the standard 1K km maintenance, which came in less than 2 weeks so maybe that's the same thing?

Check if a throttle body has pulled out of its boot... Total stab in the dark, but I've had it happen on an older SV650...

Engines can pop/backfire through the intake if something is way out of whack and a de-booted carb/throttlebody can do that.
