My 2005 harley fat boy fell over in the garage.The kick stand must of slipped out.It fell on the left side of bike opposite the side with oil fill tank.There was a large amount of fluid that leaked out.It stinks really bad like its burn't.Is that transmission fluid or oil. It looked to clean for oil.This is my first bike and don't know what to check first.And how do I refill the fluid tanks with a cold motor?All the directions say to have a warm motor.

Top right side just below yer engine oil reservoir but above the frame rail about 10". An allen head plug, approx. 5/16ths faces up & forward @ about a 45 degree angle (it's your dip stick too) Takes about 1 qt. ??? Q is...how do you DRAIN it ???

Stand the bike upright. Remove the dipstick from the oil tank. Remove the drain plug on the bottom right side of the frame. While the oil is draining, replace the oring on the drain plug. Remove and replace the oil filter, after filling the new filter half full of oil. Replace the drain plug. Put 3 quarts of oil in the oil tank. Replace the dipstick. Start the bike and check for leaks. No leaks, you're done! I use HD Syn 3 synthetic oil in my '04 Fatboy, but you can also use a conventional 20w50, as long as it's made for use in and air cooled motorcycle. Don't use car oil!

theres 3 which one? Primary left side of bike bottom of inner primary just below derby over, transmission under bike between rear shocks , oil is right side bottom in frame just in front of pivot shafts . 5/8th plug

It should hold between 36 and 44 ounces. Stand the bike as straight up as you can and still be safe. Remove the derby cover and drain the old oil. Refill the primary with oil until the oil level is right at the bottom of the outer clutch drum. If you fill it too high, your clutch will drag and you' will not be able to find neutral with the engine running.

Good Luck

The oil drain hose comes of the lower back side of the oil tank on the right side of the bike. It runs down behind the transmission and comes out just in front of the swingarm down low on the frame. It either dead ends there with a plug in the end or it connects to a crossmember of the frame that runs underneath the transmission. If it connects to this crossmember, the drain plug is on the bottom side of the crossmember directly opposite the hose.

Good luck

I believe all 2005 Fat Boys were EFI and no production models w/carb. Generally, the difference between an EFI tank and carb tank is that the EFI has a fuel return port. If you look at the left side bottom you will see what appears to be two fuel lines. One is supply and the other is return from the fuel pump. I believe 1999 was last year of carbed Fat Boys. Left side tank has only one fuel supply port.

About a quart. Stand the bike straight up and remove the derby cover. Fill to the bottom of the spring in the clutch assembly. Do not overfill or you'll be unable to find neutral with the engine running.

Good Luck

look Under bike,just in front of rear wheel. You should also see oil filter there

Grretings!

Sounds like your gear box is wounded... actually, its possible excessive gear box oil is comming out the vent. Check the gearbox oil level before your next ride and check for leaks.
