I had a small leak at 1 control valve bolt,got it to stop with some locktite and tighten her up nice.Thanks to all who responded.I would really like to hear from some other BX owners as to how they removed the bolts on to of the valve,got some really experienced folks on here,but there has to be an easier way to replace simple rubber O rings...After 10 years of hard use this was the first issue with it,read some other threads and their tactics seemed odd,although the placement of parts on her are just as odd.
