H-D Cooler adapter question?
Anyone know if the HD adapter with thermostat routes oil through the filter before it passes the thermostat and then gets directed to the heat exchanger; the same way the JAGG adapter functions. I don't want to start another "to cool or not to cool" argument, just looking for this specific info, thanks.

In a thermostat type sytem the filter will always get hot before the heat exchanger does, regardless of the location of the thermostat, so that observation is not a proof positive indicator that the oil passes through the filter before it contacts the thermostat and goes to the cooler. The thermostat could be located upstream of the filter, oil would be directed to the filter first, making it hot first, until the thermostat opens, then the cooler would get hot second. With the thermostat upstream of the filter, oil would be directed through the cooler and then back to the filter before going on to the motor. Eventually the oil is going to pass through the filter weather the thermostat is open or closed. I guess I could simplify the question by asking does the oil get filtered befor or after the cooler when using the HD adapter with thermostat.

No, I don't have the answer I'm looking for. I do fully understand the the oil flow path in the Twin Cam, and I know how the JAGG adapter works because I have one, so I was able to trace the flow of oil through it. I don't physically possess one of the HD adapters, or I could figure it out also. I didn't think it would be a far stretch to get this answer out of the forum.

This is an interesting question in regards to how the adapter works, but does it really matter? The oil will go through the filter all the time regardless of the sequence and the oil will flow through the cooler once the thermostat opens.
I'm just trying to understand why it would make any difference to us as riders. The only thing I can think of would be the possibility of the cooler being plugged with contamination if the oil went through there before the filter.
