I salvaged some engine parts out of my '91 FXRP after my accident before I allowed the insurance co. to take it away. The parts are as follows, EV 27 cam, andrews adjustable rods, lifter blocks and hydraulic lifters all with 2,000 miles. I would like to know if I could expect any problems if I were to install these into my '98 FXDS. I checked the fitment through some catalogs and found they will fit but I need to know if there any implications as to installing used engine parts from one bike to another.
