engine noise

Hey everybody. I'm new to the forum and just picked up a cherry 1983 XS with just under 2800 miles. Its a real survivor. The seller shared with me a video of the bike running with the mystery whine. Tried to upload the video but wouldn't let me. Sounds just like a couple other clips I've seen on...

Hi Everyone, In the last month or two my bike started making this whining noise. I've changed out a number of parts recently while restoring the bike, specifically the clutch plates/springs. I have tightened and loosened the timing chain and adjusted the ignition timing to match since this...

Hi all: Jim has kindly offered to post an amateur video of an odd new noise that my 1976 C-model began making last night after a spirited ride. She starts and runs fine - but there is a rapping / knocking sound that I’m sure wasn’t there before. This morning I adjusted the timing chain and the...

So i'm honestly not sure if this noise is new or maybe I just haven't noticed it before. Cam chain tensioner/valves done correctly about 500 miles ago nothing on the bike has changed. It isn't a distinct metal knocking nor a carb chirp but its something in between the two. I can only hear it...

I searched the threads and from what I found the cam chain guide is worn. I took it a trusted shop (because...

Hey all, I just had a guy swap out my clutch (because I'm completely inept mechanically) and when he got done there was a helluva sound that's progressively gotten worse. I've attached a sound clip. What could it be? I took it to a shop and they told me I'm looking at $1000+ just to tear it down...

I've got a weird grinding/whining noise coming from the clutch side case. It is coming from around the kick arm. I used a screw drive to isolate the noise and thats how I found the location. Neither me or a friend has any idea what it could be. We've replaced the clutch basket before we isolated...
