Slow air loss

[kenwshmt2]

I think my bike tires loose about 10 pounds psi in 2 days, and that tapers off to about 60 psi remaining after a week where it looses no more.

My copy bike's tires would loose about 10 psi in 2 weeks.

Has anyone any suggestions, or luck, on improving the retention of the tires?

mmm... not a solution, but for a reference, my A-bike loses about 10 to 20psi in a week depends on how much I rode. Even I don't ride it at all, rear tyre loses 10psi at least.
