My thread!
Yeah my head gasket looked exactly the same when I took it apart. I put a new one in and voila bike ran perfect again. You can always lap your valves and clean the carbon off your pistons (strongly recommend WD40 for that!!). But you'll need to have a tool to put the valve collets back on the stems after you're done. Cleaning the pistons is plenty easy just make sure you orient the rings and pistons themselves properly after you're done.
