I'm not sure why you would think that would be a fix for your problem at all. The gasket around the plug hole is torn down the center as a result of too little clearance between the cover and head when bolted down, causing the gasket to compress to an excess and split. I agree, I did the same thing as him initially because I had read it on here that it was "the" fix, but ended up ripping another gasket in 20 hr's or so. This last time I just torqued the valve cover bolts a little less to take off some pressure. Seems to be lasting longer now but not a sure fix until i get more hours on the bike. Both times the gasket failed it was very warm out as well.
