103 Stage II Builds - Feedback
I have read numerous comments and feedback on the SE 103" Stage II engine build, with the 255 Cam, and am looking for comments +/- on your results. I am looking to get this done in two weeks with excitement to my 2009 Road King Classic. Already have a SE race tuner, Rinehart slip-on's and a Wimmer Better Sucker high flow airfilter.
Appreciate any feedback - also, posting under engines.

There is a major difference over a stock 96. I thought the 96 was a dog from the start, but the 103 kit with 255 cams made it a winner. The only thing I have different is V&H Monster ovals. It has not been tuned, just a basic download. I want it tuned by next Spring.
I had a stock 88 motor on a Deuce and the 96 had less performance. The 103 is faster than the Deuce even though it is a couple hundred pounds heavier.

Make sure you have a builder that pays attention to the little details, such as deck hight, squish and can cc your head chambers to get the compression as close to the cams "favorite" compression. The dealerships generally slap them together without spending time on those lil details,..... and those details often make the difference in "who buys the beer" after a race with your buddy!
The motor will be apart anyway, might as well put it back together the bestest way possible.

I didn't do the ACR's and it's ok. Some hot start issues. If I was doing it again I would think about it. I love my 103 build ,lots of low end. Are you doing the heads? It was worth it . Like others have said pay attention to the details.

It makes a big differance in how it rides. Lots of power. Its too early to tell for me. Its been to cold for me to ride more than 600 miles be it seems to be hotter than a 96 but that could be my dyno tune and power comander

Go with the compensator...
There are several fixes if it has starting issues later but all are more expensive if not done with the inital build. Not all will have issues and need the compression release but why not now when it is easier. Love the improved torque in the RPM I spend most of my time in... mid range.

I really like my 103" build. I had some hard start issues when the motor was hot. It's all taken care of now. That's a topic that I don't care to discuss much anymore because there are so many who want to argue about what they think will work and what won't.
I have ran my bagger against several different types of bikes with several different builds. It is not the fastest on the road, but it surprises most who run against it. The best part is all the tq I have in the normal cruise range. I twist the throttle to pass cars without downshifting first.
It's probably not the best build for lighter bikes or people who like to ride in the upper rpms alot, but it fits me just fine.

Try some Andrews 54's at about 9.9:1 to 10.2:1 and you'll get a cool running well behaved motor with lots of low end grunt along with some high rpm power too. No need for compression releases. I run mine at 10.4:1 but I am pushing the limit there.
