for a blacktop thats meant to be in decent condition i would think more along the lines of 190-180psi with 5-8psi lee-way between each cylinder, anything less then its not a real healthy motor.
After first test put 20-30mls of engine oil down each cylinder then retest, if new test numbers or more then 5% higher then the first test then rings are pretty worn.
Post up your results for all to see.
