I have a 12 flhx. Motor is stock except for a PC5 with auto tune kit, rhineharts, and stage 1 kit. When I accelerate from a stop or accelerate after making a turn the oil pressure drops to around 10 psi or less but comes back up when you get up to a steady speed. No light has came on. No abnormal noises going on. Oil level is correct. Bike has almost 18,000 miles and is still under warranty. I've always worked on my own cars, and bikes but have never have seen this problem before. Any suggestions besides take it to the shop?

 

No worries; 10-12psi at hot idle is fine. Should run up to 32-34psi at cruise. Early models would show about 3psi at hot idle, sometimes the oil light would blink on/off at a stop.

 

Oil pressure is 32+ at all times except under moderate acceleration. That's the only time it drops and then comes right back up.

 

32psi at hot idle is not normal and dropping under acceleration is not normal. Gauge could be faulty; check with a manual guage.
