Hello, <br /> I just bought a 1990 130 yamaha (V-4). The upper cylinders have 145 psi, the lowers both have 135 psi--Any reasonable explaination??? and would that be acceptable comp. for being 12 years old?? Also,I would like to check the oil injection system. Is there a good way to be sure it's sending enough oil?? Thanks for any help....Ken
