i have a 2004 sporster custom with led tail lamp and turn lamps with engine running i have no running lamps or brake lights on rear but have all turn lamps working fine please help me with this problem also ihave checks all fuses and the brake lamp switch they are ok

SOURCE: left side turn signals ( front & Back) won't work

Check the bulb for the actual indicator light on the dash

SOURCE: accessory fuse keeps blowing, headlight not working

I know this sounds aomewhat general, however please give the following some thought:
Check your relays, if you have an aftermarket horn you may have a different relay. To troubleshoot unplug your headlight, unplug your horn, etc.. Turn your ignition switch to accessory only. See if the fuse pops. If it does unplug whatever added accessories you may have still have plugged in. Once you can get the fuse to stop popping, turn the ignition switch to on. Then one at a time plug you accessory, headlight, etc. back in. When you find what pops the fuse, unplug that item, start plugging in the other items, if the fuse has not popped you have potentially isolated the circuit causing the issue. Now check the wiring for loose connections, bad ground, and CHECK the relay if that item has one. Hope this helps,

SOURCE: oil blowing out throttle body on filter and

The oil may not be coming out of the throttle body. The crankcase breather system is actually in the rocker box covers. Yes, there is a breather gear in the crankcase but that is for the oil return to the oil pump.

The crankcase ventilation system vents crankcase pressure into the air cleaner as required by the EPA. The purpose is to route oil mist contained in the crankcase ari that is vented into the engine to be burned. There are 'umbrella valves" in the center section of the rocker boxes. Over time, the heat makes these pieces get hard and brittle since they are made of a type of rubber. When this happens, they don't stop the oil mist as well as they used to. The oil mist is blown into the air filter where it coaleses into drops of oil. This is normal for any Harley due to their engine design.

But, if it's too bad, I'd suggest replacing the umbrella valves. Simply remove the top and center section of the rocker boxes by removing the six bolts that hold the parts on the top of each cylinder. Replace the umbrella and the edge gaskets and replace the covers. Torque the bolts to 10-13 foot pounds.

Good Luck
