Bone stock HP? 80 may be to high. Between 53-64. I'm using this reference of course: http://www.nightrider.com/biketech/hplist_twin_cam.htm

Torque, between 66-78 stock.

The factory specs the tq between 84 & 86 lbs. depending on model. I was told the stock hp was anywhere from 62 to 64. The site Sarge links to looks more realistic.

Maybe 80hp at the crankshaft but close to 63-64 at the wheel on a dyno.

The website Sarge mentioned above shows 67 hp and 80.4 torque for the stock 2005 FLHTCI. I guess that's at the rear wheel, correct?

A recent Cycle World article shows the stock '06 SE FLHTCUI with the 103" engine at 79 hp/79 tq. rated, although I don't know where the number came from. They loved the bike but hated it's $33.9K price tag.

No more problems but waiting to install what I should have done a year ago on the original build.

Anxious to try the GP Pinion Support in the primary with the 3:37 gears. And I am very anxious to try the complete Feuling setup in the cam side.

And of course getting the Forged rocker supports in for that piece of mind.

Thanks for asking.

If that 103 only made those numbers I would never want one for sure.

Your mileage may vary but my "stock" bikes made those numbers on a NEW dyno jet with PC III, and those 2 other mods.
