Normal compression
« on: September 14, 2014, 01:27:08 AM »
Had a look around old posts but couldn't find anything along these lines. What are people seeing when there do compression tests on normal in service gsf400's?
Mine were 125-135 which seems low compared to the book. Getting the impression that might be ok in the real world.

Cheers,

10 - 10 - 10 - 8,5 (bar)

still working. measurements were done in cold state thus warm may be higher especially in the cylinder with low compression.
