Wondering what to do to wake up this 103. I bought it with a set of rinehart duals, se air kit and a pciii that has supposedly been dyno tuned. (Previous owner didn't have a printout of the tune, but it runs smooth with no decel pops or other problems, I've never put it on a dyno personally.)



I was wondering what you folks that have had the cams changed in these early 103' did to yours and if you had it to do over---
Would you do it again? 

I've looked at all the dyno sheets I could find on here, but what I really would like to know is how much  "bang for the buck" you guys got for what you did.

It looks like Redshift and Yuill Bros make cams specific for this motor. I've read where some said the Redshift cams were noisy, are the yuill's also noisy?

If I just replace the cams with one of the above and re-tune that's probably the most cost effective route for  a hp/tq bump.

Or go ahead and have the heads worked and use another cam?

Just looking on a little imput on what some of you have done, and would you do it again. ( if not what would you change)

The Rineharts are staying, they're paid for and I like them.

Thanks

I would deck the heads .040-.050, put in a S&S 570 cam with ez starts and do a .030 headgasket and little bit of headwork.  Sach's
on this site does a lot of these builds and would be a good guy to contact.  CVOSTU has this build as quite a few of my buddies and they run great.  I think Stu's numbers are like 119 torque and 116 hp.

At 10:1 compression hard to beat.

Just had the zippers 575's delaminate in an 05SEEG after 35k

Had Sachs do just what Unballanced said above. Runs sweet

[Cvostu]

can't beat this set up... be nice to John   he is da best!!!

I 'm kinda interested in this query also. I bought an 05 SEEG about 7 months ago. It was all stock with 10K miles on it. Did a Fuel Moto tune with a PV and FM's Jackpot mufflers and an AN big sucker. Really pleased with the performance boost but I know I'm gonna have to do the tensioners in another 10K. Don't know if I should change the cams when I do the tensioners or not. It's my understanding these things came stock with SE-253 cams. Read a lot of the older posts on here but I too am interested in what has worked best over time.

Anyone have a dyno of sachs work?

id go with gear drive cams... the S&S 570s are great with THAT 103..   Add some compression, good exhaust,,TTS and a good tune,,  you will be very happy   OH,, clean those heads up too

[Sundog1258]

Went to my tree farm for a few days, thanks for the input. Anyone had problems with the ez start cams
Phil

[Cvostu]

My 103 starts easily with my set up.

[Sundog1258]

Andrews cams? set at what compression?
Thanks,
Phil

Sundog,

It is sorta comparing apples / oranges, but to be sure that is a 110 with the 54's, only change to the motor is they put in a .030 headgasket to raise the comp just a tad for the 54's.   Its approx 9.7 to 1 if you go off an avg of the pistons being .005 in the hole.

Should be roughly 182 cold cranking  and static compression of 9.73

Hello Sundog, I also have a 2005 SEEG. I installed a redshift 575 gear drive cam. Did not tear motor apart, just cut pushrods and installed adjustable ones. Had it dinoed at 99hp/109tq. Love it.  Tony

'Chose to leave this one stock, except for K&N and PowerCommander.

It'll "smoke" the 110 that has K&N, V&H PowerDuals, Fuel Pak and Throttle Pak!!!

I just love tellin' the boys it's stock (the stock mufflers are still quiet at almost 50k mi.) after I get into their feelings

The only thing in the motor is update the tensioners with Harley's "kit"

Those '05 SEEGs are runners!! And they handle good!!

Whatever you decide to do, keep us posted

You know, I've been reading a lot of threads here on upgrades. I took my cam cover off at 25,000 mi. just to check the chain tensioners. The outer one was a credit card deep so I put her back together not looking at the inner shoe. At  30.000 mi. I heard a rasping sound at idle on the cam side so decided to park her and do the cam upgrade since  I'd check this out. Holy crap... the outer shoe was not much more them the credit card depth worn. But the inner shoe was fricken worn almost down to the steel backing. chit from the shoe was evident in the cam plate ports every where. This could have taken out  my engine. So I cleaned her out, bought all the Harley upgraded  hyd. Cam plate, adjustable push rods, 204 cams, new lifters, new cam gears, new high output oil pump, new inner Timken cam brgs, new gskts kits, etc. Got a Race tune as well. Put her all together had to redo the oil pump alignment, cause nobody told me I had to turn the fricken engine twice over before tightening the oil pump to the cam plate. Once done I tested her out and had a rasping noise on the left side. Took off the chain cover and found the compensator nut backed right off grinding up against the housing. Firetruck sakes...what next... Cleaned her up and torqued her down with red loctite and took her for a test. My does she pull now. Those 204 cams come in at 1800 and pull right up to 6500 in all six gears. Gave the Race tuner back cause I did 115 with this old pig bagger in a 1/4 mile stretch. Happy with that.

Badass2,

You gave back the Race Tuner did you mean SESPT, but anyhow since you changed your cam from the 253's to the 204, how are you tuning the bike to handle the air / fuel changes that need to be corrected ?

FWIW and to set the right expectation on the cam the 204 while a good cam gives up the ghost at around 4800 rpm.
