I have an 06 yzf450 and I was wondering how many of you had to adjust your valves after the break in. Thanks for the info

Mine didn't need adjusting but still should be checked.

It rarely needs anything, but occasionally, one will settle into the seat very slightly, so it's worth checking. I now have two YZ450's that have never needed a valve adjustment.

Be advised that you will probably find them at the tight side of the spec range. They're built that way.

It's most probably because the valves are still in spec(have a gap); if there's no ticking, then you need to worry.

Have you considered taking the rather bold, adventurous step of actually checking your valve clearances so you have some information to work with, or would you rather simply speculate infinitely?

If it is in need of adjustment sometimes it will be responsible for the ticking.

To test for that, all one needs to do is touch the lever at the head while the bike is idling and ticking. You should not be able to feel a definite shock in the lever from the lifter hitting it. If you do, that might very well be your problem. Check your valves anyway. It will be good for you.
