i did my first valve adjustment today, the write up is excellent. had to make one phone call to dad during the process, for a little more explanation, but all in all it went good without any difficuties, except for the strong gust of wind half way through process blowing my print of the write up away. blew it out from under my drill, across the road up over the neighbors house and into the woods, that was alittle nerve racking. had to adjust the exhaust side, they were all .002 out of adjustment. intake side was still golden. i'm sure this was the first time the valve cover was off, and i was at 14,175, so it was a good way to spend a sunday afternoon. anyone considering doing it themselves or taking it in to a shop, i can eaasily say it is rather easy, so do it yourself.
