What are your objectives for the stage 4? Let us know what you are wanting, and we can probably get you pretty close.

No idea what "stages" are.

I think that Harley calls Stage 1 a free flow airfilter and slip-ons, Stage 2 is a fuel controller and full exhaust, Stage 3 is big bore, no cams, and Stage 4 is big bore with cams.

Oh, in that case, go directly to stage 5 - big bore stroker with cams.... or stage 6 big bore stroker with cams and headwork.

you left somethign crucial out. stage 8, which is all of the above, with the addition of carbon fiber parts to replace 90% of your steel bodywork and whatnot for a savings of another 150 pounds, along with a blower running 4 psi boost into your motor and a holy book of your choosing affixed to the bars for handy pre ride prayer.

HD lists only stage 1 & 2 kits that I could find.

Gotta link?

If you go by the little dyno comparason charts, they are very optimistic.
The most important thing with whatever kit you do put in is tuning.

BTW: Stage 9 is having to sleep out in the garage with the bike after the Missus sees the CC bill.:

If you're going by the "dyno graphs" in the screaming eagle catalog, those are horsepower and torque readings as measured from the crank. Expect about 15% less when measured on a dyno due to drivetrain losses.

Well, it looks like they changed it since the last time I downloaded the SE catalog (2007?).

I just downloaded the 2008 one and they are now listed as rear wheel corrected.


Sorry for the confusion.
