I have a 2000 XT225, 6000 miles, great condition and i have completed a lot of preventative maintenance in the last few weeks. Today i adjusted the valves and found the clearances pretty tight. But got them adjusted correctly. Started it up and it sounded great just purring along. But i didnt get to warm it up and ride it.

When i had it open up i felt like i had some side to side play in the rocker arms. Both the intake and exhaust felt the same. Tomorrow i will start it up and pull the oil pressure bolt and check that i have good pressure to the top end.

But is any play normal? should it be rock solid or just a hint of back and forth? Is there a actual spec for side to side play?
