Look at my exhaust cam in pic,
my Dyna 07' FXDi has only ~5k miles, all stock, and the exhaust lobes show witness from the rollers of the hydraulic lifters.

This bike only carries 3 Qts of oil, any thoughts of why this is? Oil pressure? Lack of oil?

I discovered this while changing cam bearings, and will also be swapping cams to a set of Andrew's with quickee pushrods. Crank runout was less than .003" also.

 

I would post that in the tech section. There is a good number of builders , Hillside to name one that will be able to help you out with this

 

Normal

 

The cam in the back of the photo is normal, the front one is not. Maybe a local mechanic will help you out?
