Rattling sound

[drifter-paul]

1 - Crack the throttle (like a hoon) in 3rd at about 60K/35MPH . If it takes a second for acceleration to catch up - you have worn clutch plates .

2 - Check this post . rear spark plug on right side of motorcycle, forward spark plug on left . You will see a recessed ("23 mm") hex plug . remove spark plug and check for groove in each aluminum tunnel . This will tell you the cam chains are worn and rubbing thru .

3 - If mechanically minded, you can find articles in this forum to replace the Cam chain tensioners -  and replace the convex/ concave plates in the clutch - these wear first -   otherwise refer previous answer

Hey @moto

If I were you, I'd take the motorcycle to a local mechanic or motorcycle shop and have them listen to the noise.

It might be a minor issue, but it's always better than getting stranded on the side of the road if something breaks down along the way.

There is a rattling sound coming from the right side of the bike at idle, but it disappears when the clutch is pulled in. So, it only occurs at idle or at very low RPMs.
Is this serious? Could the clutch be failing? The transmission works fine, though, and all the gears engage smoothly.
