Compression Check - Review??
What do yall think of these compression #'s????
These PSI #'s are shown as you look at the motor from in back of it. (orientation)
130 130
127 126
120 121
Seems like the cyl. in the top of each bank are higher and the lowest cyl. in each bank is the lowest. Is this normal for the lower cyl to wear more / faster. Could it be due to higher heat down low??
The total spread is 10 psi, so I thought that was pretty good for a 20 year old Yamaha V-6 (225hp)
