hi all. I had a 2006 honda trx 400ex that had 115 psi compression before I went to adjust the valves. I could not stick the .004 feeler gauge in both sides so I adjusted both to where the feeler gauge had a little pull. Went to crank and 0 psi! Yes the engine was TDC

So I played with it adjusting them a little at a time and could not get over 0 psi.I removed the valve cover to make sure timing was good and its spot on. Did a compression test without the valve cover on and got 50. Put the valve cover on and now its 0 again..

This is not my first valve adjustment on a quad but this one has me questioning my ability to fix these lol. Any help would be great.
