250EX Valve Adjustment

[400excracer]

So I am ready to adjust the valves on my brother's 2006 TRX250EX and I am having a hard time finding the plug so that I can turn the crank. I found the plug on the left side with the mark so that I can find top dead center, but I need to find the other plug. HELP!

Both plugs are on the left side cover. One large and one small. The large one exposes the head of a bolt. You can put a socket on this to turn over the engine manually. The small plug lets you see the timing marks on the flywheel. Then you just need to find TDC and remove the two tappet covers on the valve cover.
