Well, found a bolt I didn't check during my first service the hard way. Lol. Kept hearing a weird clattering/rattle around the top end of the engine after start up and at certain throttle conditions, mostly when engine braking from mid to high RPMs. Started doing some hunting and found this bolt missing:
It's the bolt that goes through the clamp that seals the muffler to the header pipe. That clamp is surprisingly loud when it rattles just right, lol. No biggie. Found a M8 bolt that's 35 mm long, I think it's a 1.25 thread pitch, but I don't remember, and is a cheap fix. I'll throw some thread lock on it and call it good. Just figured I'd share the first one I've found missing or loose from vibes. If you have some you'd like to share, post 'em up in this thread.
