Finished install on my brothers 06 883 custom for a new set of bars and cables. When I removed the primary cover I noticed the oil did not look like the primary oil in my road king. I know they are two different bikes but his oil looked more like a dark gray color instead of the clearish light tan color im used to seeing. Is it cause its a sportster or should I be looking to inspect the clucth hub? Could it be rubbing the friction plates some where inside causing the oil to be gray? Or is that the normal color and Im over thinking things? Bike only has about 3500 miles so I never cracked open the primary until now.
YES
The Sportster is a Different animal. IT's Primary SHARES lubricant with the Tranny..
Completely different as the big bikes have 3 places for oil and the sportsters have TWO. (engine and primary)
I would recommend to use
HD's Formula + in the Tranny shared Primary-clutch area.
Formula+ is Wet Clutch approved and also a good Gear Oil.
Big TC bikes could use it in their tranny OR in their Primary (some do)... But many other choices for me in my TC's then Formula+..
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 a HD Sportster oil filter.
(make sure the filter is for a sportster. Using a TC oil filter will burn up the sportster motor)
Now in my big bike, 09 FLHR
I use
Redline 20/50 engine and a HD oil filter (for twin cams)
MTL Redline in the clutch/primary (not for sportster primary/tranny)
Redline Heavy ShockProof in the tranny. (not for sportsters at all)
As far as the sport primary/tranny/clutch lube color, It may be due to the type of oil used? and OR in need of Changing.
(first change? over due in My Book)(second change OK at those intervals)
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...
Don't tighten UNLES you know what you are doing.... Much damage can be done IF you tighten it Tooooo tight.
And Not the proper way.
