A faulty main bearing seal on a two stroke engine
can allow the fuel mix into the magneto area
and cause running problems. Transmission oil
should not reach this area at all. Check the seal
and also check for other possibilities like a crack
in the engine cases. Two strokes can be pressure
tested to ensure a good seal.

hi mate it could be to do with the correct mixture off oil/petrol you should buy a mixing bottle on ebay with a ratio of 32/1 and make sure the choke is off when you ride it good luck
SOURCE: have devolped a small leak on 2005 road king.
Spray it off at the car wash to remove all the oil , then spray Right Guard (Yes, that Right Guard) on the area of the leak. It will show up, but you may not be able to see exactly where. There are a couple spots where it can leak. The jackshaft oil seal, as you said, transmission output shaft (clutch shaft) on the trans itself, the inner primary seal where the trans shaft runs thru, the engine sprocket shaft oil seal, inner primary O-ring, the bolts that hold the inner primary to the engine/trans, the primary chaincase gasket and the drain plug. Hopefully when you get it apart, you will see which seal is leaking. If not, replace them all. Still want to fix the leak? LOL
SOURCE: High Idle On Start-up.
Most fuel injected motorcycles do start up in a "fast idle" mode. Although I don't know much about fuel injection on Harleys (H-D will not tell you much about it unles you are one of their technicians), I don't think the system is equipped with an engine temp sensor. Since the crank case sensor get it's pulses from pockets cut into the outer edge of the left side flywheel half, the sensor will have oil on it.
