Re: pulling the head??
Theres nothing to a 4-stroke like that. Pull yer tank and stuff off. .Theres two bolts holdin the cap ontop of the cylinder head. Pull them out... then you can see your rocker arms and cam shaft. . .pull the nuts off the top of those four bolts, and pull the rocker assembly off. Be careful for the dowel thingies on two corners. .take the cam sprocket off the shaft, and carefully take it out, loop a wire through the chain so u can suspend it from your frame. Then use two nuts to take each of the four studs outta the bike. Take out the camtensioner (if its on the cylinder head, i dunno what year your bike is) Take out the bolt on the left hand (flywheel) side of the head, and lift the head clear. (you'll have to move the camchain down through the hole.. its all common sense). Theres two dowels below that too, so be careful not to lose them down inside. ..Then u can lift the cylinder clear as well.. Ta da, now you got your cylinder stuff off, and can replace your gaskets. Just make sure u set the timing right when u put her back together.
