Cam and tensioner upgrade S&S? Screaming Eagle?

Looking to replace stock cam tensioners on 03 Electra Glide. Should I upgrade to SE plate and Hydraulic tensioners? Should I replace cam at same time? Upgrade? Not looking to build a rocket, just want dependable great running bike.

Any help would be great!
Thanks,
Chake

Go with the newer setup and you may want to replace the lifters also.

SE203's are what I run. :thumbsup :thumbsup
Check the cam bearings...I used the SE upgrade,cam plate, oil pump...working great....but when they got in there the cam bearings were the bigger problem so replaced them and put new cams in also....

Just be sure to get the Screaming Eagle up-date kit , not the low ball kit . An SE-204 cam with new S&S lifters and (Torrington) cam- bearings up-grade , then you should be good to go !

Why the SE204 over the SE203 ????????????
oops
Why the SE204 over the SE203 ????????????
:know
Cause I like that lumpy-cam sound .......just my personal choice .
Both are bolt-in cams but your right , the 203 is better for a heavier bike . The 204 has a little more grunt on the big end ! Either one is really considered a good low end torque cam though .
Thanks!
Think I'm gonna go the SE route. Like the sound of more low end with the se203. will I need to remap the EFI?
If you're going to go with hydraulic tensioners, you'll have to upgrade the cam plate, and if you upgrade the cam plate, you might as well throw in the SE high-volume oil pump. My 2012 103 went from 32psi of oil pressure at 3000rpm hot, to 48psi, and from practically zero at hot idle to 15psi. Oil can't lubricate or cool if it's not circulating. You might want to look at the Zipper's dual-piston cam chain tensioners also. If you're building for reliability, it won't hurt to improve the oiling system and go with a better tensioner while you're in there. As far as cams go, you could do a lot better than an SE, as their smaller cams tend to favor the EPA over anything else. Do a search for "Twin-Cam Camshaft Comparator" and check out the options.
Thanks! I'll check it out! Definitely want to change tensioners, and while im at it ill do the oil pump. Plate will change no matter what so for a couple extra $ might as well do cam. Gonna go with adjustable rods so think lifters can wait a bit.
I did the SE oil pump upgrade with the hydraulic cam plate.

The cam plate kit does come with an oil pump, stock on the 2007+ bikes which are higher flow than the spring tensioner bikes.

The SE oil pump is higher flow yet than that.

07+ pump PN# 26037-06 - increases flow by 8% and scavenging by 22% over stock pre 07 pump (comes with hydraulic tensioner upgrade kit)

SE pump PN# 62400001 - increases the oil supply by 23% and scavenging by 50% over stock pre 07 pump

Lifters are too cheap not to replace while you got the cam chest opened up IMO, especially on a 11 year old bike.

Yep, I did the SE kit (P/N 25282-11) in my 2012 FLHTC at 10K miles. Came with the SE cam plate and SE pump. I did this specifically to address what I considered to be low oil pressure in a basically stock, low-miles 103 (=/<38psi hot @ 2800rpm, 0-5psi hot @idle). To me, you can't have too much oil pressure as long as it's being scavenged and you're not bursting filters. While I was in it, I also replaced the inner cam bearings with Torringtons, and I installed the Zippers dual-piston cam-chain tensioners, even thought the stock units had very little wear.

I'll eventually upgrade the cam, lifters, and push-rods, but I wanted to increase reliability before I increased tq/hp. This is my long-range bike, and I don't want to have to worry about something simple breaking 1000 miles from home. When I want to amuse myself around town, I ride this:

Agree! One of the finest rides I've seen.

(I would like to see you stage it for a portrait with a more complimentary background)


Oh, and Welcome to the Forum!

Thanks man. S&S 124 w/a Mikuni HSR48, IST ignition, 675G cams, head work, and D&D Boarzilla exhaust. I'm at 148ft-pounds of torque, and 152 HP right now, and I can't get enough back tire under it. It'll pass anything but a gas station.
Oh, and Welcome to the Forum!

Thanks Silverback.
Love the colors and would love to have that much power.

Thanks man. It can be interesting when the back tire breaks loose at 50MPH in third gear.
