Clutch issue

hi Guys, not a triumph but whilst trying to get the wife's Yamaha YZF 125 sorted. The clutch/engine clunks as it finally engages its fine on the bite it's when you fully drop it. I have changed oil cleaned inspected plates all looked ok. Have fiddled a bit with cable adjustments but still same. Could plates be warped? Any help appreciated thx

 

Thx,
Chain all good, Cush drive is a good call, seems a little flack will strip to mix, thx Matt

 

Cush all ok, front sprocket is very wiggly, cleaned and seems ok for wear, lookedon yam forum old posts say it's common and a non issue. Seems odd to me but all other posts refer to new clutch plates and a decent semi syn oil, so gonna change them.
