You can geek out on Oil and Filters with this guy's information:

Be careful with the primary. It may or may not take a full qt. Overfilling it will make the shifter feel like crap. Download the manual and follow the directions EXACTLY. While you're in there it's a good time to adjust the clutch and check the primary chain tension too.

I'm changing mine for the first time today. The swing arm was black, but the oil that came out of the primary was red. It is a xb12r firebolt. Is there something better to run in there? I was planning on using the same Mobile1 as I did for the crankcase. Advice?

I run mobile1 in both on my sportster, but this thing is made for racing.

Red is transmission fluid. Its perfectly normal to use Type F transmission fluid in the primary.
My XBSX has had type F trans in the primary for the last 11k miles with no issues. In fact some clutch manufacturers such as energy one specifically call for it in the instructions.
:D

You can change back if you like but id make darn sure to let that primary drain before putting motorcycle oil in it. Id also change the primary again after a few miles just to make sure its flushed out good. Whats 1 qt of oil.

I'm finding out this bike has had a lot of custom work done to it. 27,000 miles. Who knows? I'm heading back to autozone... I'll give her what she's used to. Thank you Cosworth!
