Default Raced Harley Fat Boy 103

I was on a poker run yesterday and one of the guys I met up with had a 2011 Harley Fat Boy with the 103 upgrade and a stage 4 kit (whatever that means). He and I raced from 5 mph up to about 75 mph.

We were neck and neck the whole way. He seemed to have to shift alot more that I did. No one won, I would call it a tie.

Just a story for reference.

After some looking around, here is what the stage 4 kit includes:

From the Harley Company Site:
"This Street Performance kit provides the maximum horsepower output for a legal 103 kit that will maintain the factory warranty.
Kit includes
  • Screamin' Eagle® CNC Ported Factory Cylinder heads
  • 58mm ETC throttle body
  • SE-259E cams
  • 10.5 to 1 compression pistons
  • Perfect-Fit pushrods
  • SE clutch spring, and all required engine gaskets

Street Performance kit produces 103 hp and 110 ft-lbs of torque
All EFI-equipped models require ECM calibration (priced separately)"

I bet he had a lot more $$ into his rig than me....

Cams, throttle body, pistons, and new heads. I would think he had a lot more than you into it. Sportsters are the fastest HD outside of a V Rod.

Default harley upgrades =$$$$

theres a lot of aftermarket support for outdated harley powerplants because it takes a lot of $$$$ to just catch up to anything more modern as the vic is!! their biggie is almost nothing to adjust beside the fluid changes and of course worn-broken parts!! harley sells bling + look i am driving a harley! "big deal" when i tested an 08 hammer everyone was "lookin"

He had more money into his rig before he even thought of the "stage4" kit.

If you can do the work, for about $1,00 or so Lloydz would put you clearly out in front for probably about the same as he paid for his bike.
He'll need a rebuild way sooner too !!!!

But....we will never have that "harley sound"

If he spent that much on that bike and he couldn't walk away from you then I would say you kicked his ass.

At least he should be pissed............

Well, boys and girls, the difference is right there in front of us. Victory owners can make 130+ HP with the STOCK HEADS and STOCK THROTTLE BODIES. The HD is lucky to make 1 HP/CI with aftermarket heads and big ol' 58mm throttle bodies.

In all seriousness, if you want to make power with a Harley, the best way is to sell the HD engine on ebay and buy a real engine from S&S, R&R, G2, or have a 120R prepped and beefed up by a competent builder. It will be cheaper in the long run and more reliable to replace the engine than to try converting a stock Twin Cam into something that makes strong power reliably.

If the 'stage 4' HD engine has a stock bottom end/crank, I'll bet dollars to donuts it won't live long if he flogs it. The OEM pressed crank ain't much. The best money spent on one of those is weld/plug/true/Timken bearing treatment on the bottom end. You didn't build your house on a foundation of Dixie cups, did you?

He had a LOT more $'s in the bike and then even more $'s in the engine work so figure you are probably around $5K less $'s sunk into yours.

The other thing I (love/laugh) about are the HP/TQ "claims". I'd like to see a stage 4 harley actually GET those numbers. For comparison, your Highball probably came stock with around 83-87HP and the stage 1 might have gotten it up to around 92-94HP, right? If he had actually gotten anywhere NEAR the numbers they "market", he would have walked you.




It's not just any victory.... It's MY Victory!
