The book says to pull your left side case and spin to Top Dead Center with a wrench to line the "T" up with the "notch", but there's a nice little hex plug that you can take out to see the "T"... is it ok to put the bike up on a stand and instead of spinning to TDC with a wrench, just spin the wheel in gear to line up and then adjust the valves? Seems reasonable (and a lot easier) than pulling the side cover off.
