What is the engine compression specs for the '91 KDX 250?
I tested mine and it is about 160 psi or 1100 KPA.
Is that still within specs?

Starting to get low but still within spec. The manual says it should be between 145-220 psi or 1020-1550 kPa.

Thank you for the quick reply!
Yes I also think that I will have to do the top end in the near future.
