Hello everyone. Recently bought a brand new bike (well, almost), with 1k kilometers only. Made 2.5k km on it, now it smth around 3400km. The bike is 2025 model year, always put decent petrol.
For the recent few rides I’ve been noticing strange sound from the engine. Does anybody has/had the same? It doesn’t look like a cracking sound, so I want to believe the chambers and the pistons are good. Besides that, there are some stains around gasket, but from what I heard it’s common for these engines.
And yeah, I’m kinda new to motorcycles, so I tend to believe it’s a stupid question and the bike is fine.
Appreciate any help :)
