if 120 on all bores, leave it and test it once run in.

Compression ratio makes alot of difference on any engine on a compression test.


Dont forget, alot of cheapish compression testers will read different to each other.

Did you test it with good battery, hot oil temp, throttle open, and all plugs removed??


On my cossie, runing 8.0:1 cr, is 165-168 psi on all 4..
