That is the cam chain tensioner. Don't mess with it especially if it's running. It keeps the chain that runs from your crank to your cams tight.

Are you messing with the cam chain tensioner? 8-[ I'm not sure from your description...but from what you're saying, that would be my guess. :-D

ummmmm i turned it once while turnin it over.... does that meen i screwed it?
please tell me i didnt just wreck it

If the bike still runs OK, you're fine.

I sense that you have an inquisitive nature. To help satisfy your curiosity, here's a GS850 cam chain tensioner disassembled and rebuilt. It may look a little different than yours, but they all work exactly the same:

ya the problem is its not running to begin with so i dont know if i screwed anything.....if i did mess it up how do i fix it??????

once agin thanks a million for the help

You didn't mess it up... It'll spring back into place... But just don't touch it again, especially when the bike is running

Curiosity killed the cat...I had the same experience when i got my gs (used to ride Morini, with no camchain.) I dismantle the tensionner to se how it works. It still works ( Thank god!) I can se there is no point in touching it at all, I can imagine all kind off bad things that would go wrong if I mess with it while the engine turns, but what would be the hazard off touching it while the engine is stopped?

Just Curios.

A quick test to see if it is still in time, pull the number one spark plug and tap the starter to bring the number one piston up to the top of the stroke. Then, with a spark plug in the number one plug wire, and grounded to the head, (you're going to be looking to see when it sparks)put your finger over the number one plug hole and spin the engine over. What you should see is, when you feel the compression against your finger, you should see the plug fire (on the compression stroke...you'll also feel some compression on the exhaust stroke). If you don't, you'll have to pull the valve cover and check the timing marks on the cam. It is possible to have an engine that is 180 degrees off time, but you wouldn't achieve that by simply messing with the cam chain tensioner. Good luck.
