Warm the engine to ensure maximum oil drainage. Steady the bike on a stand or secure jack, as close to level as possible. Ensure the availability of a pan that can contain at least three litres of oil, with enough extra room to lift and move the pan. Slide the catch pan under the center of the oil pan, and remove the large oil drain plug from the center of the oil pan. If the catch pan is large enough to reach the oil filter, loosen the filter at the same time to allow better flow. Once the oil has finished draining from the plug hole, replace the plug and torque to setting. Remove the oil filter. Apply a film of oil to the gasket of a new filter, and install the new filter as per the manufacturer recommend tightness as listed on the package. Remove the oil filler plug on the left side of the engine case and pour 3 litres of 10W40 or 20W50 (depending on climate). Replace the oil filler plug.

The two switches you are having problems with are thermetically controlled; they can easily short out which will cause the light to stay on. First what I'd like you to do is disconnect them at the sending unit, if the lights still stay on you have a short somewhere deeper in the wiring. Most likely it will be a grounded wire. If the lights do go off you will then want to use an OHM meter to check continuity at the senders. If you get solid resistance then the sending unit is shorted out, if one remains open then isolate the other. You may have a situation that one switch is causing both to stay lit.
Let me know if this helps you out at all. Tell me if you don't have the resources to co the diagnostics as described and I'll be happy to give you a work around. We will just have to be a little creative.
Either way let me know and I'll be happy to help you resolve the issue. I'm inclined to thing your problem is a short not a heat related issue since both sending units are both indicating a problem.

You don't mention which intake you have but you probably DO know that this motorcycle is Fuel Injected.
If you're using the stock intake, make sure the air filter is clean.
I'd also -highly- recommend that you clean the throttle bodies near where the butterflies are located. These are known to carbon up and the little ring of carbon around them impedes airflow.
Next (again if it's a stock intake setup) get yourself a can of Sea Foam and introfuce it into each throttle body per the instructions on the can.
I use a syringe and fire 10cc's directly into each TB, shut it off and let it sit for a ferw minutes.
Seafoam in the tank will help clean your injectors as well.
I always use it in higher concentrations then called for and the bikes always resond well to this treatment. Fact is, the bike would run just fine with only the seafoam in the tank,
Are you running an aftermarket FI controller?
These can be adjusted as well.
I own a 2005 Drifter 1500 and an 06 1500 Classic with 24000 and 51000 miles on them respectively. FINE MOTORCYCLES.
