Just a reminder for those that have a 2006 YZ450F and haven't upgraded the shift arm to the 2007 verion. I've been tearing through the top end and decided to pull the clutch and check things out. I remember reading, back when I first got the bike, about potential problems with the shift arm as documented here in the stickeys:

'06 YZ450F: Hard Shifting, Inaccurate Shifting, Jumps Out of Gear


Well, when I got the clutch pulled here is what I found :lol:

These are all the parts I could find in the oil sump. All the balls seem to be gone (but I do think I saw at least one of them attached to my magnetic drainplug last oil change) and I am hopeful that the rest have cycled through during oil changes.

Here is what the 2007 version looks like - I certianly don't think I'll have problems with my balls anymore! :)

So everyone do check this . . the BALLS you save may be YOUR own!!!! :lol:

Same thing happened to my buddy! The only way he knew it was when he changed his oil he saw the bearings stuck to the magnetic oil plug. I always use the magnetic oil plug. A perfect example. We actually fixed it in about an hour, and the bike run perfectly. http://www.yamaha-mo...4/0/detail.aspx
