Default What compression should be showing?

Hi all

1997 uk classic.

Compression is showing as 125 on all four cylinders.

Also if anyone has run out of fuel, has this caused any issue?

Cheers
Dave

Thats not to bad, All cylinders even on a classic which has i guess done a few miles?


Running out of fuel shouldnt cause a problem. Unless maybe you were running it really really hard and caused some det, But its unlikely.

125 psi on all cylinders is low (should be approx 160+psi) but it will be enough
to fire up and run the engine.
Would be looking at the fuel/ignition system if it wont run.

125 PSI "even" won’t cause any running problems as above it will start and run fine just a under power. Maybe you could give more info on what’s happening?
