I like your thinking NoSuperSlabs.

@Brent526 if you know someone with a similar year Sportster that isn’t modified to a trike you might want to ask them to check their oil level hot while sitting on the jiffy stand and if at the proper hot level then hold their motorcycle straight up and then check the oil level on the dipstick while straight up. That should show you where your trike’s oil level should be at.

After checking with this other person’s Sportster the question would then be, does your hot check compare to that person’s straight up level?

I don’t think there would be a significant difference in the level but maybe it is enough to cause your issue.
Great idea now to find one to compare

I believe you are just thowing stuff at the problem and have not determined if you have low oil pressure. Check it with a master gauge. If it's not low, then the oil pressure sending unit is at fault. If it is low it may be several things and all are internal problems except the oil reg. valve. Because your problem occur at temp it sounds like worn pump or reg. valve. Or the oil ring Tank mentioned earlier. The oil sending unit is before the filter and would not be affected by a filter plus there a by pass for plugged filters.

   I hope I didn't offend anyone by being so blunt but I was trying to get him on the right track.

I don’t think anyone would have took that input as anything but words of experience.  :)

I don’t think there would be a significant difference in the level but maybe it is enough to cause your issue.

I have a 2016 Sportster Custom and have had extensive conversations with the service department over several oil issues (long story for another time).  What they have told me may be of assistance.

1. Oil level is to be checked hot and with the bike on the jiffy stand, and as soon after shutting the engine off as reasonable.  The level should be between the half and three-quarters mark, slightly lower is OK but not higher. 

If the oil is too high you would run the risk of it blowing back from the heads into the air cleaner.  The oil/vapor is then sucked into the intake and then into the combustion chambers, if too much the filter gets overwhelmed plus the unburned oil can build up in the cylinder.  If the oil level is too low you can simply add oil.  If not checked promptly the oil can sump back into the case and thus give a false reading.
 
2.  The Service Manual shows the following.  This applies to all XL models and the pressure reading is taken at the oil pressure switch fitting.

Table 3-16.  Oil Pressure:  At Operating Temperature

1000 RPM  7-12 PSI   43.3-82.7 kPa

2500 RPM  12-17 PSI  68.9-117  kPa
Never attribute to conspiracy that which is adequately explained by incompetence.

Brent, did you ever find out what the problem was, and how did you finally resolve it?

I looked in a 2010 Sportster manual and it doesn't say anything about checking the oil when the bike is level. It only covers the check that would be performed when the motorcycle is leaning over on the Jiffy stand.

In a Touring manual they show the dipstick level check for a motorcycle leaning over on a Jiffy stand and also the dipstick oil mark that would be done with a bike in the upright position which they call the "sidecar use". The Touring motorcycles have dipsticks that have two different sets of marking on the dipstick, one for Jiffy stand and one for sidecar use.

Here are the two side views of a Touring motorcycle dipstick.
