Welcome to TT!

Can`t offer much help, but will suggest the Make/Model Specific portion of the forums.

I was given some great advice there. Start the thread over maybe; if you don`t get suggestions here.

I'm like no smoke can't offer much help on that one but someone i was with the other day had noticed this on a yz250f .. said its been like that for a while..think he was going to make it a winter project and just rebuild it and hope that helps

Have you checked the valve clearances ?

a little bit of valve tick is normal i would check the clearances, i had a cam and bucket randomly burn up on my crf250x which made a bit of a ticking sound

The valves were checked when put back together. Its normal for them to tick i understand that but this is a much louder tick then normal.
