The very expensive, very special, hard to find tool i use is an old round-style bottle opener, the kind that "loops" over the bottlecap. I stick one end in the slot, stick a screwdriver through the loop and twist. works well for me. also convenient for enjoying a brew or two while working
Now this is just what i think, and i'm not sure of it, but i *think* you have to have the timing plug cover off to line up the timing marks during the valve adjustment. finding TDC is only the first bit, the timing marks hit maybe a 1/4 turn or so after. But again, i'm not sure of that.
Again on something i *think*: the raptor is not vacuum driven, so setting it to on should allow fuel flow to fill up the carb bowl. this also means it is a good idea to shut it off when you shut the bike off. my raptor hasn't come in yet, so i can't promise that i'm telling you the truth.
How was the cam chain tensioner? that is next on my list for when the weather gets too nasty to ride. still kinda intimidated by it though...
