Cams swap - slowly but surely.

Cams swap - slowly but surely.
As I posted several weeks ago, my 'winter' project is to do a cam swap in my '010 FB, so I spent the better part of today doing the prep work. I decided to keep the OEM pushrods rather than use the adj kind, so I removed the tank/console + rocker covers, in addition to the exhaust + foot controls + cam cover. After a good nights rest, I will tackle the cams tomorrow - yank the EPA sticks and put in the SE 254E set. Hope to post successful results when finished.

SE-254E cams are in!
SE-254E cams are done!
Working slowly and methodically I was able to complete the SE-254E cams install last night. Went for a shake-down run today and all's good - no strange noises or leaks. Idle is smooth, exhaust sound is not that much different than the stock cams. If you’re looking for the classic hot-rod Harley “po-ta-to, po-ta-to” tune then these cams aren’t for you.
Power output, though, is noticeably up over the stock bump-sticks, right from idle and on up to at least 4000 rpm - I’ll rev it higher once the new parts are properly broken in. It felt good. One surprise I didn’t expect was that there was absolutely no popping on decel, and I tried to make it happen three or four times. I am planning on adding an auto-tuner sometime in the future (T-Max, PowrVisn) but right now it seems the XIEDs are up to the task so I’m in no real rush.
I used the Heartland cam puller/install tool kit that comes with new B168 bearings, and except for one minor detail the tool kit was of great assistance in getting the job done. Out of the box, the fingers on the puller were spread a little too far apart to fit into the old bearings, so I had to tweak the fingers a bit with a small hammer before it would slide into position. The installer is set up so that the bearing is automatically pressed in to the proper depth - no guesswork on your part necessary. Overall, it’s a great kit, and the fact that it comes with new bearings makes it a very worthwhile investment at $115 or so.
I wasn’t as happy with the #C9664 Cometic Cam Service Kit however. The gaskets weren’t cut/punched very cleanly and needed some “detailing” for the install. Also, the rocker cover gaskets don’t come with the silicone beads like the MoCo’s, so I ended up going down to the dealer to pick up some OEM gaskets. One other comment: there are a variety of O-rings required for the install, and you have to carefully match up the old and new rubber parts by eye as there is no description/drawing included with the kit. Given all the above, if I ever have to do this over again, I would just buy OEM parts to begin with.
All in all, I’m completely satisfied with the cam swap and actually enjoyed wrenching it myself. If any of you have been walking the fence on tackling this kind of mod, take it from me - with the excellent S&S vid, your service manual, this forum, and a lot of time and patience you too can get it done.
Here are some pics - I will create an album on my member's page after I sort out the rest. Thanks for your interest - ride safe.
