125-130 is pretty standard, but it's probably lower because of its age, and its a smaller motor so probably closer to 100.

Time for a re-ring. Bump that up to 115-120psi and get a few more ponies out of it!

alright thanks i just checked it and it has 100 in both
That isnt too bad for an 89' 400cc motor. If it dips much lower re do the rings.

Might not be worth it just for a couple HP, depends on what its used for.
