Just did this. Haven’t gotten a chance to ride it yet.
Values went from #14 -17 closed, 101 open, #15 -18 closed and 101 open. New values #14 -13, 97 & #15 -14, 97
The bolts required a little more loosening than I thought they would before it would move. Also my small gear wrench bit set was the perfect size for the job. Finally, I used a bar clamp in spread to hold the tank up. Worked great.
I’ll include some picture.
