Haven’t seen this posted anywhere so thought I’d pass it along.

Andrews and many forum members have posted lists of the parts required to convert to 2007 camplate & “N” cams. 4 parts on those lists are included in Primary Drive Kit 25585-06. If you purchase the kit, it will save you around $85 or more compared to buying the included parts separately. I found this out recently just trying to be able to order less parts. Another savings is to use SE Oil pump 62400001 compared to stock ’07 pump 26037-06. This is the high volume pump from the Hybrid cam plate kit 25284-11. I have read some discussions regarding the lower priced SE pump and all were favorable.

Primary Drive Kit 25585-06 $34 at Boardtracker. Includes:

25675-06 Chain, Primary Cam Drive
25728-06 Sprocket, Cam Drive, 34 T
25673-06 Sprocket, Cam Drive On Crankshaft, 17 T
25566-06 Cam Drive Sprocket Retention Kit

The last 2 pages of the instructions for Hybrid cam plate kit 25284-11 list the primary drive kit and its contents, so you don’t have to take my word for it.

The cost of the sprockets, chains and stock oil pump had always bothered me. I was also considering the above SE Hybrid kit, but once I saw the primary drive kit & SE pump prices, the 2007 upgrade became more palatable and if all goes to plan, I’ll be putting in 21N’s this weekend. It's also getting new inner bearings and lifters.

 

You'll love the 21's.

 

Great post! So what was the net savings purchasing everything this way over the 25284-11 kit?

 

just added cams 255's to 07 softtail and did the cam plate upgrade, (came with new high volume oil pump) with kit ($499.00 from HD). well worth the money, also changed lifters (S&S) and inner cam bearing, (B38) wish I had checked crank run out while we were there, might be surprised or feelings hurt!! hint, hint if you are doing this work,, check it!!!

 

I am going to be preforming the same upgrade on my 2003 Fatboy and was wanting to know how the screaming eagle oil pump worked out, and anything I should be concerned about. Also will be installing Andrews 21n cams, and did they give you a little more low end and midrange torque ?

 

I installed 21n cams over the winter in my TC88 - I love them!

I went with the stock '07 cam support plate, '07 stock oil pump, and roller chains front and rear. The SE kit still leaves you with the silent (multi-plate) chain on the rear.

The 21's have really smooth good low to mid range pull. Great for solo or 2 up back road twisties. They do run out of steam at higher rpm's, but I don't spend much time there any way. Plenty of power for passing etc... I'm running a V&H FuelPak, motor runs really well and much smoother throttle response than stock. Mileage is about the same, except I don't seem to get into the upper 40's like I used to on occasion.

 

Sounds great. I will be installing the 07, cam plate also. I am going to use the screaming eagle oil pump if possible since it is a little less costly, If it can't be used with the 07, cam support plate I will have to go with the 07, oil pump. Thanks for the info on the 21n cams, sounds like what I need. Just purchased the 2003 Anniversary Fatboy with only 4600 miles from a guy who I have worked with for years and which he purchased new. Since I will be pulling the cam cover to check the tensioners I might as well change it to the newer hyd. tensioners since I will be putting a lot more miles on it.

 

Only 4600 miles? Most don't check the tensioners until 20-30k miles. You should find them in pretty great shape.

 

Yep only 4600 miles amazing I know,but he kept it in the garage covered and rode it only about 300 miles a year. Rebuilt the carb, bike looks like new. I know they don't wear out that quick but with age and them being plastic I will feel more comfortable checking them and replacing them with hydraulics.

 

I think he just liked sitting in his garage and looking at it. I'm going to ride it. Had to talk him into selling it.
