I finally found the leak! When we drilled & tapped the manifold for mounting holes, we drilled into the compression plugs at the of the manifold. I found the leak by accident! Yesterday, we made another manifold. We drilled the 1/8" air gallery slightly off center to allow room for the mounting holes....worked perfectly! I went for a ride last night with the bags aired up to 15 PSI, I found the ride a little rough. I dropped the pressure to 13 PSI & that was a little better. Out again today and dropped another 2 lbs to 11PSI. I wonder how low I can go without damaging the bags? Any advice anyone???
TIA.
