[TR] TR4A - Compression Check Numbers

All,

My engine, with 87mm pistons, now has 700 miles on it with no issues. (knock
on wood.)
Just ran a baseline compression check for future comparisons.
Numbers were as follows:

1 - 165 psi
2 - 167 psi
3 - 169 psi
4 - 168 psi

Looks like a good grouping, but do the numbers look good for the mileage?
Unlike the cam lobe lift numbers, I cannot find any compression numbers in the
manual to compare these against.



Cheers,
