I have a 2004 Heritage, recently purchased. It has screaming eagle big bore heads, cnc ported, with manual compression release valves. When should I release the compression? It currently starts right up. Should I release them every time I start it or just when it has difficulties?

I don't have any idea of the static compression or what cam it has in it. The HD dealership had it listed as an 88ci, but my understanding is being it had the big bore kit installed, by the previous owner, that it is actually a 95ci. Could it still be an 88? First bike so I have a lot to learn about the parts and mechanics.

Should do it every time you start. You don't want to be paying to have your starter clutch replaced cause of wearing it out by not using compression releases.

Is it carb or EFI? If a carb bike, you may wish to only use one of the compression releases so that the motor creates enough vacuum to assist fuel flow through the vacuum operated fuel valve when it's been sitting an extended period of time.

Going down the road at 60 mph. If it starts fine without them then don't use them. Was the starter changed to a high torque? That's one reason you won't need to use them.

Press them down every time you go to start the bike.
Especially when it´s warm.:nod

I was told every time before starting it period. Just get in the habit of pushing them in once you shut the bike off.
