What oil change schedule do you use for your track bike?

I have a bike that I use exclusively for track riding. If I go by the bike's owner's manual, I would change oil every 4000 miles. I'm at only 2000 miles since my last oil change, but I wonder if track riding puts more stress on the engine and so requires more frequent oil changes.What do you think? via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/b6chrc/what_oil_change_schedule_do_you_use_for_your/?utm_source=ifttt
