Just broke in my new YZ250F, and I'm checking the valve clearances. I can't get my feeler gauge into the middle intake valve, because of the bracket that holds the camshaft. There is a slot that goes through through the bracket and to the middle cam lobe and valve bucket, but my gauge is too wide to fit through it and as far as I know there aren't "narrow" gauges you can buy. So do I just check the outer two intake valves and assume the middle is about the same, or do I take off the bracket that holds the camshaft down? If I take off the bracket I'll get a false reading won't I? Thanks for any help and info.
