Doing Cams: Why Bother Unbolting Oil Pump From Cam Plate?
Doing cams on a 2007 FXSTC.
All the instruction I read calls for unbolting the 4 bolts that hold the oil pump to the back of the cam plate, prior to removing the cam plate assembly from the engine.
It seems as though you could just as easily slide the oil pump out with it bolted to the cam plate. This would also negate the need for rotating the rear wheel to align the oil pump when reinstalling.
Why is this step necessary?
Thanks

not required
not necessary, unless you are changing the cam plate or oil pump. in the instructional video supplied with my FM big bore kit the oil pump is left intact and reinstalled with the cam plate. hope this helps.

Please tell me a little about cams. I've got a new Road King and tomorrow I'm getting the mods added. I've paid for an engine upgrade...adding a cam. I know my service man at Harley will do it right...I'm just wondering if that means one or two cams. I'm paying about $1,000 for this upgrade. I'm expecting to feel the extra power. Will it meed one or two cams? And will the increased power be easy to feel?

Those are not called cams on the camshaft , there called cam lobes , 1 exhaust and 1 intake , they are ground at a precise degree on the cam to achieve a desired valve timing. A camshaft is one piece including the lobes.

Nice video's, very informative. I have an 06 so when I go in to do mine I am going to upgrade to the SE kit so all that is coming out of there anyway. Has anyone gone to the SE kit, hi flow and scavenge oil pump? Shoot, come to think of it most of you's guys bikes are newer and don't need that upgrade. Mine also only has 6k miles on it so I am in no hurry. I have many miles left before I have to change them out. I probably won't wait until it needs it though, I really like the idea of having that higher output oil pump with the high compression motor I'm running. Anyone? Gone to that SE kit? Thoughts? Tip's? Any noticeable difference? I am told it will run a few degree's cooler, true? Thanks in advance for any input.
