Did my second oil change on my 07YZ450f and it was a pleasure. i checked my oil gallery bolt like the manual says and noticed that a little bit of oil built up around the head of the bolt but never actually flowed. i ran the bike idle for a little longer to heat up the oil and noticed the oil was barely flowing. maybe a drop total. i've done a search and everyone usually skips this step. and what i have found is that during idle there is not much oil pressure. do i need to be worried?
