Fe 650 -08 14h and main bearing failure?

Sorry for my bad english , but feel free to ask if there is something you don't understand. Bought an almost brand new 2008 Fe 650. It had 8h on It when i bought It and was in mint condition. On the last ride I started to hear a rattling and knocking noise from the clutch side of the engine. I left my buddies and rided slowly back home.Back home in the garage I started dismantle the clutchcase becouse I suspected that the nut on the primary pinion came loose. The nut was tight but when I pulled on the pinion , It moves about 2mm in and out. There Is no play up and down. After a closer look in the drained oil I found little fragments of what seems to be coating of a bearing. The prime suspect at this time is one of the main bearings. Does anyone have any experience of something like this? The bike is a 2008 Fe650 that has 14h of drive time on It :cuss:

But my float is 2mm.... I will try to attach a video later. It doesn't looks alright to me.

To be sure I will try to borrow a dial gauge so i can meassure It. I pray you are right Taffy. I will update if I find something.

I think I've found the problem :cheers:
The woodruff key that secure the primary gear is almost in two pieces. The gear itself was a little loose but the nut was loctited tight??? I used a shim between the gear and woodruff key and tightened the nut. The float seems to be within the tolerance and there is no longer any noise when the engine is turned over. I will replace the woodruff key and secure the primary gear and nut to the shaft and see what happens. Thanx Taffy for your input. A new update will be made when I get the new stuff.

The problem is history :cheers:
A new woodruffkey and loctited the gear to the shaft solved the problem.
