Oil Pressure and Neutral Swith issue 2003 Sportster 1200

Bike has been fine but after a couple days sitting I cranked it to find the oil pressure and neutral lights did not come on. I checked the fuses and everything is OK, power on both sides of the fuses. I checked power to the wires going to bulbs with the key on but I get no power. I also checked for any loose wires but find nothing. Was considering replacing the ignition swith since both of these lights get power from it.

Pin44, good day, i dont have a harley but i do work with bikes. good news is, with the way you describe it, theres nothing wrong with your oil pressure and the engine itself, some elements may have coroded the contact of your ignition to the LEDs, you may clean it using pressured cleaners of wd40 (be careful not to apply too much) or replacing it instead.

if you have more questions just let us know.

good luck.

Just replace the ignition switch because due to moisture it might have been damaged

Why is my 98 1200 Harley Davidson Sportster building pressure in oil reservoir and filling up and smells a little bit like gas

Mitchel. Fuel is probably getting into your crank case/oil because of sticking floats in the carburetors. Do not run your bike in this condition, severe damage could occur to engine. If you must run to get it to a shop for carburetor check/rebuild change oil first or have bike trailered in.

Just need to know where the drain plug is on 2003 1200 sportster-friend lost her manual

For the oil? On the oil tank you will see tubes coming off the bottom of the tank, there is two one to the motor and one will drop almost straight down. follow the tube and you will see the plug. most times it will sit right behind the tranny on the rh side of the bike. don't worry about the motor holds little oil and the tranny is separate and holds its own oil.
If you need more help please let me know

While warming up the bike in the driveway I heard a sound of metal slapping metal....( only one time ).the oil can indicator comes on when the bike is in neutral...the light is located on the dash...when...

I don't like the sound of that on two counts. The oil pressure warning lamp should come on only when the engine is not running and stay on until the engine is running, whether in or out of gear.
The metal slapping sound is possibly, due to the cold weather depending upon the high mileage, piston slap. That is not too serious in the case of an Iron Head, (like my 1963 XLCH1000) as they have done many miles but a newer machine it is somewhat worrying.
A good friend of mine has a 1200 Sportster. His problem was oil pump. The pump couldn't keep up with the engine revs and he finished up on one piston, the other was in the sump.

Make sure the oil pressure is good and check for dirty oil. If the bike has not been started for a while, the dry sump fills up with oil and that causes odd noises until it clears ina minute or so.
Check that oil warning lamp!!!

Is there a certain brand or weight of oil I should be using in my 06 sporster 1200 custom?

20w/50 synthetic

04-up is 3 qts.

Drain oil hot, r&r filter, put in oil,........let a couple ounces drain out of the hose to bleed the air out to prevent cavitation inside the oil pump.... run engine about 10 minutes, shut off & let sit for about 2 minutes. Check oil level with bike upright, oil should be at top mark on dipstick, fill as needed.

Don't forget about the Primary Oil...1 qt.

Also remember, there is WAY more to maintaining your bike than just an oil change, belt tension, throttle cable lube and adjustment, clutch adjustment, clutch cable lube and adjustment, primary chain adjustment, brake inpsection, tire pressures, fork oil every 10k miles, steering neck bearing lube and adjustment every 10k miles, etc.

No oil pressure

rhondatim990 If this is true your motor would have seized up. I would not operate your bike until this problem is clarified. Hook up a analog type oil pressure test gauge asap onto your oil pressure sender port.

What kind of oil does this bike use and the tire pressure should be what?

If the bike is 2005 Harley Davidson XL1200 Sportster, it uses Harley Davidson Syn3 20W50 oil. You can use any good petroleum or synthetic oil of this weight as long as it has a API code rating with CG or better for use in diesel engines. Amsoil makes a good substitute or Mobil V-Twin.

Tire pressure is 30 psi in the front 36 psi in the rear

Easiest or best way to add an oil pressure gauge to an 88 harley 883 sportster..

to add an oil pressure gauge, you'll need to put the pressure pickup tube at the same place where the oil pressure sending unit is now.

I've seen oil pressure gauges on Big Twins but I don't recall seeing one on a Sportster. I guess I ought to warn you that installing an oil pressure gauge on a Harley engine can cause you to have a heart attack. Why? Because when the engine is idling hot, it has very little oil pressure. The oil pressure sending unit is designed to turn the oil pressure light off at four, yes I said four pounds of oil pressure. The Harley engine is a high volume low pressure system. The reason for this is because it has roller bearings on the crankpin, not shell bearings like *** bikes. So, unless you get an extremely accurate gauge, when your bike is idling on a hot summer day, your gauge will read zero.

Besides, you have the best oil pressure gauge one could ask for in that engine. They're called hydraulic tappets. If you lose oil pressure, they'll let you know very quickly. They'll rattle so loudly that you'll be forced to turn the ignition off.

I have a 2000 1200 custom sportster. It leaks oil out of a overflow tube under the seat.It leaks on the rear end when riding or on the grnd when parked. One mech replaced trans seal, still leaked. Another...

if the oil tank is above the crank case, inspect the oil pump check valve. go online and study the check valve's functional purpose and see to it that the vale is operating properly. it should not be an expensive fix.
if you reroute hose be carefull of rear tire annnd what does the oil level in the oil tank sit at when full and after the leak happens after -say a day of riding- a week
