You will need a head and base gasket. That is all I replaced. You may want to get the tensioner gasket also. You dont need a valve cover gasket unless yours is damaged or leaking or dosn't come off in 1 piece. Its rubber and rarley needs replacing. You may need a flywheel cover gasket. But mine came off fine. It may be an o-ring gasket. I cant remember. I just bought the yamaha gaskets. They wern't that bad. Then again I never looked aftermarket to see how bad the dealer rapped me. Cometic may make a gasket kit I am not sure. As for the flywheel puller. You yami shop should have an aftermarket puller for you. That is were I got mine. That puller fits a large % of yamaha MX bikes and quads. Let me know were ya find the 1/4" torque wrench. No one local has one around here. I have found a few places online but nothing local. I need to get one also. have been putting it off.
