    I finally received new valves for my Kawasaki FB460V but have not found how to determine Top Dead Center (TDC) so I can gap the valves. Is TDC when the piston is at the top of the cyclinder or some measurement below the cyclinder?

    Thanks in advance.

    Top dead center is just that, the piston is at the top of the stroke. If you are going to adjust the valves you have to have the engine at TDC on the compression stroke. You do this because both valves are closed at this point. You dont have to be dead nuts TDC a few degrees either way wont make any difference.

    Pull the spark plug, crank the motor over by hand with your finger in the spark plug hole, when your on the compression stroke it will blow out the hole. When you feel compression you can stick a straw in the plug hole and you can feel when the piston reaches tdc.

    Thanks for all the info. I replaced the valves, cleaned the seats, gaped the valves and she cranked up on the second pull. Appreciate all the advice.
