After a winter outside (under a roof) my bike started to make this unholy sound. I think its coming from near front sprocket, can't be sure cause it only happens randomly under load while going under 20km/h or when accelerating (also only low speeds, however i can't be sure if it happens on highway cause of wind etc). Doesn't matter if clutch is engaged or not. Right before she went for winter nap i got new sprockets, chain, oil and air filter and oil change. Everything was completely fine before. There ain't any performance issues with the bike but I'm just scared it will explode or something on a highway or that I'm damaging the engine. Also i haven't once heard the sound when the engine is cold, only after 5-10min of driving.
Short audio from ~10min drive

That metallic rattling clanging in the begining mainly ?
You may have a poorly adjusted chain. Since that's the last one you futzed with. And likely it wasn't lubed all that well at the factory.
You sure its from that sprocket cover ? Yea possibly - it does sound very very dry. If its from ahead of that in the alternator area it could be your stator and rotor hitting each other.
Cool.

Thanks for the reply.
Chain should be fine, 23mm slack at the tight spot when I'm sitting on the bike without any stand and i lubed it twice just to be safe before first ride :laugh: But yeah, im not 100% sure where its coming from cause it only happens while driving but I'm fairly certain it comes from the left side of the bike, somewhere in the center.
Sounds like something loose rattling around. You sure you didn't leave a screwdriver or something under the seat?
Check the exhaust header bolts, if one of the header giant washer things (not sure what you call it that clamps the header to the engine) was loose it could sound like that.

Checked, all good, however i saw something completely rusted very near my chain which could "scrape" against it. Gonna check it out tomorrow when i get my hands on tools :cheers:
