My 2007 BMW K1200S overheats in warm weather when riding in lower gears for periods of 5 minutes or longer. A dealer cleaned the radiator and bled the system however the problem still persists.

sounds like a head gasket problem. A minor leak there will pump compression into coolant and force it out of heater core. Any unusual steaming from tail pipe? Also: if radiator was flushed "in car" sometimes debris does not come out. Try flushing with it out of the vehicle. Jeep radiators are notoriously small for their application if not at at least 90% they will not work correctly.I'd look at the hg first though otherwise, your symptoms seem to be contradictory.

SOURCE: extremely long warm up time 25 minutes. ok once it comes on.

Just a shot in the dark- I think your main projection lamp is going bad- If the set is more than a year or 2 old it can happen. Unfortunately they are a little expensive.
How is the brightness level after it warms up??

check fluid levels, could be your thermostat or water pump. check oil. its probably your water pump or thermostat...could be blocked radiator. For bikes they have this ICE coolant you can get at a motorcycle and atv shop, it might help :) fix these problems before you keep riding or you are going to blow a ghead gasket, SPENDY :)
