undefinedI was adjusting the valves on my 2002 WR 426 and the intake buckets will not come out. The cylinder head material adjacent to the intake valve bucket is mushroomed out by the camshaft I guess since this is the cam bearing surface. I got two of the buckets out by slicing off the mushroomed lip with an exacto knife and then the valve bucket pulled straight up easily. It looks like I may have to remove the cylinder head to get the center bucket out. I use Torco T4R oil and change often and never go low on oil. Has anyone seen this problem what is the cause and what is the fix. the bike runs very strong with no engine noise.
