Heres whats required for your basic top end/ cam chain job 1) Flywheel puller 2) Circlip Pliers 3) Inch Pound Torque Wrench 4) Foot Pound Torque Wrench 5) Ball hone (I have one for sale in the classifieds!) Other than that its just your basic tools (sockets, wrenches, screwdrivers, etc) Its not very difficult to do one you get inside there. The hardest part is getting everything apart. Did mine in an afternoon. Tip: If you replace the camchain again, make sure it dosent bunch up at the bottom of the crank.
