Repair or replace center ballast bag 2001 X-Star

I just discovered a 3/8" inch "rip" in the center ballast bladder of my 2001 X-Star.
Can this be repaired (like a water-bed repair kit?) or does the pressure of filling a bag full all the time make it a candidate for replacement?
I don't want to be penny wise and dollar foolish, but I also know a penny saved is a penny earned.
Who makes the replacement bladders? Its a blue bladder about 65 inches long (the end is about 12 inches in diameter though I guess the middle expands further than that) with 3 openings at one end for hose fittings.
It sits inside a protective cover that has a 66 inch long pvc pipe on the outside that fits along the length to hold its shape.
Thanks
