hey guys, i just checked my valves on my 08 i got a little over a month ago and the left intake is out of spec but not by much. im gonna shim it into spec monday, but i was just wondering if it is normal for them to go out of spec after break in? its not hard to start or anything like that, i just checked them out of curiousty. all the rest of the intake and exhaust are fine. also, when i got to put in the new shim, is there anything i need to look out for? i did this a couple of times on my 02 yz250f, just wondering if there is anything different i need to watch when adjusting them on the 08. thanks. cheers.
