Decided to do a valve adjustment today because my engine was sounding strained and odd at 3/4 to full throttle. When i checked the valves, they were both at .08mm? Suppose to be around .04mm? So i tried to adjust the top one first, but the dang nut got stuck on the bolt thing. Was wondering whats the name of that specific peice? Valve bolt? Lol i have no clue. Im hoping my dealer might have one in stock soi can replace it. Tried for 2 hours to get it off, tried heating it under a candle flame, sprayed wd40, etc. I dont have a 9mm wrench either, was using 2 vice grips and pliers lol. Iget a 9mm tomorrow or sumthin. Was having a heck of a time getting it precisely .04mm and then :'(BAM, nut wouldnt move. It did get stuck at .08mm again though at least. Test rode just to see and it sounded like a pop can stuck under a bicycle tire noise coming from muffler....But yeah, just need help with the name of that peice.
