I checked the compression on my new-to-me 2008 BF15D today. With a cold engine and full throttle, the top was 120psi and the bottom was 170. With a warm engine and full throttle, both cylinders were 180.
Looks good to me. Am I correct? Why such a big discrepancy between cold and warm top cylinder?
Thanks
