When I start my bike after the night when engine is cold, it sounds very smooth, the engine is not too loud, but when I stop after a ride for a break and try to start it again, it feels that engine works very loud at the beginning for a few seconds and when I continue to ride engine seems much louder than it was the first ride. Has this happened to anyone? Is it normal?
I’ve noticed some slight metallic rattling sometimes when I’m riding at a low rpm over small bumps or uneven terrain. I don’t know if it comes from the chain or the gearbox or elsewhere. It’s hard to reproduce, it just happens sometimes. Has anyone experienced a similar issue ?
