Did a compression test on my 2007 America.
Each cylinder reads 125 psi after 3 compression strokes(85 degrees).
Does this number sound correct,,,high,,,,,low?
In addition, I did a leak down test.
I can hear a small amount of air going pass the rings.
Web info says a small amount can be normal. I was just listening for sound, not any number gathering.
Hope you're wondering why I did the above tests,,,,,,,,,,,,,,,,,,,,,,,
I have AFR Sensors on each header to monitor each cylinder(da).
My results are:
13.2 Left
11.2 Right.
Numbers are the same at 2500 and 6000 rpm or any throttle position.
Why are these numbers so far off? A couple of tenths, maybe. Not two whole numbers.
All adjustments on the carburetors(FCR 39), left and right are matching.
Needles, clip position, air and fuel jet settings are the same.
Air Box gone. Foam Filters. Air Inject gone.
D & D Megaphone Silencers(loudest pipes I've ever owned).
Anyone run into this?
Any ideas?
