RE: FXDX vs FXDB
Harley says there is a 19% increase in torque.
The next generation in big twin performance from Harley-Davidson
Milwaukee, Wis. (17 July 2006) -
Harley-Davidson launch an all-new Big Twin powertrain for 2007, as the Twin Cam 96/96B engine, active intake and exhaust system (for European and select international models only) and 6-speed Cruise Drive transmission feature on all Touring, Softail and Dyna models.
The new engine, with standard Electronic Sequential Port Fuel Injection (ESPFI), offers a nine per cent increase in displacement and up to a 19 per cent increase in torque (varies by model) over the Twin Cam 88/88B engines it replaces. It also features a number of design changes intended to make it smoother, more reliable and convenient to operate.
"The Twin Cam 96 has been the biggest new-engine programme in the history of Harley-Davidson," said Skip Metz, Programme Manager-Big Twin Powertrain. "There are more than 700 new parts associated with Twin Cam 96/96B. The only areas that didn't change are the cylinders, rocker arms, rocker boxes, and items in the top part of the engine. Crankshafts, connecting rods, crank cases, transmission cases, and all the transmission parts are new. We think this next-generation Twin Cam will set a new V-Twin standard for the industry."
The Twin Cam 96 displaces 1584cc, compared to the 1450cc of the Twin Cam 88 engine it replaces. The added displacement was achieved by increasing stroke from 101.6 mm to 111.1 mm. The Twin Cam 96 cylinder bore is 95.3 mm, the same as that of the Twin Cam 88. The Twin Cam 96B is designed to be rigid-mounted in Harley-Davidson Softail models, and is equipped with internal counterbalance shafts that quell 90 percent of primary engine vibration.
The Twin Cam 96 produces up to 123 Nm of peak torque at 3400 rpm, compared to the Twin Cam 88 at up to 109 Nm at 3400 rpm. Performance improvements vary by model.

schwangster: your buddy with the '02 not have a service manual? I can copy and send the sdjustment info if you need it, or you could have a read at the dealer...they should have an '02 service manual. You've got compression and rebound dampening on the forks, rebound dampening on the shocks and pre-load front and rear to play with...

RE: FXDX vs FXDB
I am really enjoying my FXDX. I thought about a street glide for a while but I just got a cushy seat, windshield and nice trunk back and I am set to travel and carve up curves.

RE: FXDX vs FXDB
Thanks Sharkey. I have seen the manual instructions when I had my 03 FXD.
My buddy set his up and doesn't touch it.
Myself, I like to screw with things, usually til they break.
At 210lbs it would be good to know the 'just set it at this' instructions.
Note, haven't picked up the bike, still on my WG.
I love it, but sure hard to keep up in the twisties.

RE: FXDX vs FXDB
I'd start at whatever pre-load front and back gives you a bit of sag when you put your weight in the saddle; may want to pre-load the front a bit for your weight and the age of the springs (they do "tire" out...) Then for compression dampening on the front, start in the middle of the adjustment range and set rebound in the upper third of the adjustment range front and back. If all else is good, such as tire quality, pressure, alignment etc. you should have a good start through the curves...a bit of front end weave when leaned over and encountering road irregularities may indicate the need for more (higher) rear rebound adjustment...if you've got time and a good quiet test road, you can try the lower range of each adjustment and see what you feel when you change it.

The FXDX is a beautiful machine. Out of the showroom it's the best handling Harley made. But with some patience and $ you can make the FXDB a great handling bike, too. AND you'll have a frame that was redesigned in '06 and made more rigid, a 6 speed tranny with all the bugs worked out of it, and a new bike. Here are some suggestions for upgrading the Street Bob:

I'm still working on mine- the detachable saddlebags, composite rotors and detachable bags go on this spring. Jay
