FAQ Sportster primary oil type

What gear oil for Sportster primary?

I would have been happy to go with Redline 75w90 gear oil in the primary but I don’t want to cause grief with the stator / yellow metals. From searching the forums it seems the only guaranteed safe oil for the Sportster primary is HD’s Formula +.

Why is the oil in my Sportster so dark?

Using a TC oil filter will burn up the Sportster motor) As far as the sports primary/tranny/clutch lube color, It may be due to the type of oil used. and OR in need of Changing. Check the primary chain free play, as it may cause the color of the oil IF the chain IS too loose and rubbing inside the aluminum housing…

What type of oil do you use in Your Sport R?

I DO use HD’s Formula + in my 06 Sport R for lubing my primary chain/clutch/tranny. ALL in one location, Filling thru primary behind the derby cover. For the engine, 20/50 Redline and an HD Sportster oil filter. (make sure the filter is for a Sportster. Using a TC oil filter will burn up the Sportster motor)

How often should I change the oil on my Evolution Sportster?

The Evolution Sportsters have a wet clutch and primary drives. It is recommended to change the oil at 1,000 miles, then every 10,000 miles after that.

How much free play should my primary chain have?

If the bike is cold, adjust the top strand 5/8-7/8″. When the bike’s hot, move 3/8-5/8″. The following steps should be followed when you adjust the chain to the low end of the spec. Set the transmission to high gear. 

Take out the spark plugs. The rear wheel should be slightly elevated from the ground. You can have a drunk friend, squaw, or circus freak turn the rear wheel and observe the rise/fall of the top strand. 

Some sprockets are runnier than others, so it is possible that some bikes have a higher or lower top strand of the chain. When the chain is at its highest point (most taught), have your trusted assistant stop turning the rear wheel. This is when the chain free play can adjust to the lowest limit.
