Don't worry about a comparison. cheapo compression gauges are great
for testing relative compression among cylinders but may not be all
that accurate themselves. Different gauges can give different readings.
Also compression readings vary with the temperature of the metal. The
factory numbers are hot engine numbers (ow! ow! ow! scorched fingers!).
your numbers look good for a cold engine and the range is within the
acceptable variance range.
Teri,
Thanks for the response. Just out of curiosity, what psi numbers are ideal
given the 87mm pistons? Just wondering what to shoot for.
I'll add some heat to the test tonight and see if the oil makes a difference.
Gracias!
