I am considering pulling the trigger on a pair of 1999 Yamaha 250's. I've read a lot about compression and gathered that consistency throughout cylinders is most important. The motors are reported to have 110# throughout all 12 cylinders. I have seen other motors with higher compression (115-125). What is the difference between consistent 120# compression and 110# compression? Any performance issues? Is lower compression necessarily a sign of remaining engine life?
Thanks,
