I drain the transmission fluid out of my 74 Sportster Ironhead thousand cc's and got about 2 quarts out of it should I put about 2 quarts back in

If you don't have a dipstick marker then there should be a fill hole. When you get the fluid to the bottom of the fill hole you have enough in it. Make sure you are level when you do this. It may or not be 2 quarts depending on where you were at when you started.

How to do a transmission oil chage on a 1980 sportster

There is a drain plug under the back end of the primary cover. Drain the oil and refill through the primary chain inspection hole. There is a "fill level plug" on the outer primary towards the front. Remove this plug and fill until oil runs out of the hole. Should take almost a whole quart when bike is standing straight up.

Good Luck

Where is the fill spot on the primarry chain on a 79 xlh 1000

Some of the Sportsters had a "level test hole" that had a screw in it up near the front of the primary cover. Look just beneath your shifter lever and there should be a screw in the primary. Remove the screw and fill the primary unitl oil runs out of the hole with the bike standing straight up.

Need to know what type fluid goes in clutch housing cover on 79 sportster 1000

Harley-Davidson Sport Trans fluid or equilivant. Now, there are several aftermarket makers of this oil. It is different from the oil used in the Big Twin clutch cover because in the Big Twin, the oil only lubricates the chain and the clutch. In a Sportster, the oil also is the transmission lubricant so it has to have the proper shear resistance and high pressure lubricant additives in it. Custom Chrome, V-Twin, Motor Factory, and many others make this lubricant. Order it through your motorcycle shop.
