Stock at 850' it was 160psi. This was on a cold motor.

i think compression goes up on a hot motor though. someone correct me if i'm wrong.

Um, i doubt like hell its got a 160 psi, and yes compression goes up as the motor gets warm.

If I didn't change heads I would take a picture. Stock when cold it would read 160psi when new (200 miles), hot was down about 8 psi. New head reads 130-135 psi and runs much better. Remember this is not static compression!

So 140 after running for 5 mintutes should be bang on.

Thanks,
