    So I went to do my regular chain maintenance the other day and instead of riding it to warm the chain, I let it run on my kickstand. Doing so..exposed something I worry about. With the clutch in, the bike was fine. However, when I let go of the clutch every few seconds or go it would sputter and shake..violently. Enough that I was worried it would fall off the stand so I turned it off. Last time I did chain maintenance, this did not happen so it's something new. Another thing I noticed was there is one spot in the revolution of my rear wheel that my chain "strikes" a plastic piece. Like..a chain guard or something. It's on the swingarm. If I ride my bike slowly, say..through a parking lot, you can hear it hit that spot. A dealership is more or less out of the question since there's no such thing here and I'm not sure taking it for an hour or two roadtrip would be a good idea right now.

    Ideas as to what's causing the sound? Maybe the chain is too loose?

    Can that be? The bike itself only has a little over 8000 miles on it and when I clean the chain it looks really good. Like new, all shiny and what have you.

    put it up on the center stand and with the engine off and in neutral turn the rear wheel by hand to see what and where the hitting happens.

    Virtually all bikes do the same thing; with the rear wheel
    off the ground and in gear, the chain jerks and clanks.

    The chain is a bit loose when up like that - as it should be, and
    most engines do not run smoothy at idle.

    As GreaseMonkey says, turn by hand to look for problems...
    What the chain bumps when off ground usually does not
    happen when down. Then sit on the bike to check amount
    of free play.

    I called the dealership and the piece it's hitting is the chain guard. If I rotate the wheel on it's stand, there's one spot where you can see it get real close to the chain guard. Maybe there's one loose spot in the chain? I'm not sure if it's tight or loose that would make it touch the guard.

    Pull chain away from rear sprocket at the very back. See how much of the sprocket teeth are exposed when you do that. Dunno...that's how we have always checked for chain wear from way back then.

    Do I need to post up the pictures of the guy who chopped off his fingers in his sprocket because he was idling the bike in gear? Or will somebody else do that? :deal

    I won't post any but I've seen those kind of photos more than once and all it took was a fixed gear bicycle (one gear, no coasting...like a track bike) and a moment of being careless while servicing it to cut fingertips off, let alone something with an engine. In my experience bicycle and MC chains do not run smoothly without a load and it is best to SLOWLY rotate the driveline by hand and watch closely for stiff links, etc. as was said...and NEVER let a finger, rag, shoelace, etc. get caught between a chain and cog

    but I AM careful! :p

    I can hear the clicking of the chain hitting the chain guard on the highway, too.
