I wonder if those little air lines are too restrictive to allow enough airflow to respond quick enough to road bumps. I can't do anything about the size of the fittings on the bags but I can use bigger lines to the tank at least.
My opinion is not really. Mines 1/4", what I had at the time, ping tanks are within 12". Just because there really isn't that much volume moving. Most others that have done this mod, whose ideas I followed, did increase tube size.
I'm curious enough to want to increase tube size but don't expect any noticeable difference so not worth the effort at this point. If I hadn't noted the decreased 'hit' & overall improvement I likely would have pursued. It could be that on ours-the probable restriction is acting as damper.
If doing from scratch I would go to 3/8" between bags and ping tanks, just because, but I'm not sure if retapping bag worthwhile, or if the distance thru a reducing ell (which was my plan) really would restrict to a noticeable point. Its one of those things only comparative testing would really verify-.
not sure if this would address your needs- there are a few threads adding ping tanks.
