HD and many manufacturies of these things start out with a
One, an Engine. in this case inline, front to rear.
Two, the Primary area is the connection between the engine and the transmission with a clutch in there also. Most use a force multipilier to gain extra everage. Hd uses sprokets with double row chains. and has for about 100 years, actually has.
Three, the transmission. Transmission has a output sproket that connects to the rear wheel sproket.
These are the three holes that require lubrication. In the HD and some others these are separate from each other with the late models
Each has its own unequie requirements as they each do a seperate job.
the Engine---Engine oil. Million choices. use the best. Million openions
the Primary---I use a light oil for lubrication and cooling. ATF is fine. Clutch is like a Automatic type in design.
The Transmission --- a gear oil about 90 Wt. and this can have EP additives as it doesn't contact the clutch.
Everybody has all kind of, mostly good, ideas about all this.
As far as what to use and where.

Whats food for though is the tiny holes the TC has for piston cooling jets.
And the plain bearings used in the outside areas of the cams.
I keep meaning to, next time I'm at the HD shop, to look at these cooling jets.

Thanks for taking the time to explain Old Gunny. Much appreciated.
I have a 2005 883c Sportster Custom and have changed engine oil and transmission oil (Formula +) by opening the big round cover, I have not seen any other hole or lubrication that I might have missed changing, or have I?
An independent study showed K&N filters fitered the greatest amount of oil on a single pass thru the filter than all comers.
Yes but on that single pass thru., the filter, what was the smallest micron the filter removed and the precentage it has removed for the KN filter as per the industry standard ISO 4548-12 etc? The HD claims that their filter is a 5 micron, but again how many passes to remove that small and the precentage it removed, also to what industry standard are they testing it?
