Do most of you apply RTV to the valve cover when putting it back on after you remove it to check for valve clearance? Also should I look for the long set of feeler gauges (I don't have a set yet). PS I love my YZ! Thanks to all the TT folks who lead me to buying this bike when I asked for advise months ago! Enjoying some nice Fall riding here in Western NY....hoping snow will stay away for awhile!
