Suzuki Z 400 motor problem "need expert advise"

[moto9]

I have a Z-400 that was making a loud chatter in the motor, so I pulled the top end and then the left side cover to see if there was any play in the crank.

No play was found in the crank, no issues with the top end, but I could feel something loose, so I pulled the motor and what I found was about an 1/8'' play between the crank and counter balancer gears.

Everything else was tight, wonder if I can get away with just replacing the gears and pins?

I wanted to see if this might be a common problem because it looks like a poor design.

Any insight is welcomed.

Ask that same question here www.atvriders.com in their Z400 forum.

cam chain tensioner failed,pull the valve cover and check for play in the cam chain...if so replace the cam chain,tensioner,and cam chain sliders.....

dont just do one or 2 of these do them all at the same time!
