Is any rocker arm play acceptable?

Hi all,

My 2008 te 250 motor seems a little noisy, enough to make me see if I can improve things.

I read that the first points to check are valve clearance and cam chain tension

I’ve been in to check valve clearances - at the top end of tolerance but acceptable.

cam chain - other than give it a wiggle I’m not sure exactly how to check, but having done that, it passed the wiggle test. - any advice?

so we come to the main event;

while I was in there poking around, I noticed a little bit of play in the exhaust side rocker arm. To me, It sounds like it could be the source of the noise, and looks like something needs replacing.


looking for second opinions from more experienced husketeers. Take a look at the below linked video and let me know your thoughts…
