By going to the 1.6 bar cap you are increasing the pressure by more than 1/3 over stock, 7.25 more psi total.
I would break loose and retighten all the hose clamps. Don't get out on the trail and find they were tight enough for 15.9 psi but not tight enough for 23.2 psi. It could be a long push back to camp. Most of the areas we ride you could not push a bike out. Not getting burned by radiator fluid should be a concern also.
