2008 YFZ450, completely stock.
Does this sound like normal engine sound or do my valves need to be adjusted?
This bike was neglected in storage for a few years but I had it tuned up a couple months ago at a shop, (carb clean & rejetting, oil change, etc). It was running great afterwards but I'm a little paranoid now that I've ridden it hard a few times that an issue may be showing? I might just be paranoid, idk. I'm a complete noob at small engine stuff. Would love to be told I'm just being dumb 😄
If a clip of me revving it harder would be helpful, let me know and I'll record another tomorrow.
