When I had my Sportster, I would use H-D Sport Trans only. I use Castrol V Twin 20W-50 in my 2007 Dyna for now.
I think I need a new oil for my 03 Sportster

Switch to the Amsoil Harley 10w60 oil....u will love it! It's billed as a 60w oil.

If you can find it, this syn blend will do an excellent job, perhaps better than the other fine oils mentioned:

Just did this the other night on my '13 CVO Ultra...Schaeffers 20w-50 in engine and the 80w-90 in transmission. Saving $$$$ on oil changes.

NEVER run gear oil in the primary. The stator is in there, and many gear oils are not kind to yellow metals (copper windings)
Indeed, the Sportster is a quasi shared sump system versus a complete unit system like the big twin EVO and Twin Cams. The primary and trans share the same oil, while the Engine is separate.

Most sport bikes have a shared sump too,so shockproof heavy will do the same thing in a sport bike as it does in a Harley.
Maybe some time learning about bikes would help you as far as recommending fluids for them

I have more than a few friends who REALLY praise Amsoil in their HD's. quieter, better shifting. In my Buell, (engine made by Harley) I have run Mobil 1 a few times and right now Valvoline VR1. I like the VR1 better than M1 in my application: quieter, less oil consumption (I was using more than 1 qt M1 every 2k miles) and it seeps a little less. I suppose I should try Amsoil but I find it hard to justify in the Buell. (thumper. miserable paint shaker!)

Hopefully not the dino white bottle Castrol 4T. That stuff is utter garbage.
