what motor ack?? 389?? 3x the ci

but, what, 7x the weight?? 6x??

that's a fast goat.

My dyna puts out (in it's current state of tune & cam) 42% more HP at the rear wheel than a stock 96" dyna, and it puts it out near the top of it's extended rev band (about 6,200 RPM). It will reach 110-115mph quickly, but aerodynamic is rearing it's ugly head in a big way at those speeds, even tucked in tight and with no mirrors it struggles to gain much more top end after that (I.E. need LOTS of staightaway)......

those are both FXR's...but very good vid...def worth watching.thanks

 

i smacked 120 the first time i was out on the street bob, but I stay around 100 now was kinda SCARY before, i dont need to go that fast again.

 

Haven't had mine over 105 yet, but I did that in pretty short order passing some folks, and me fully loaded for Sturgis, on the way there (saddle bags, windshield, t-bag...). I hate it when people speed up when you start to pass them..... dropped to 4th, grabbed 5th at 75 and upshifted to 6th at about 90... kept pulling like a train till I rotated the wrist back up at 105. Felt like she had a lot more to give.... I won't push her much past that withoug a good dampner installed tho. She was nice and solid at that speed. At slower speeds... like slowing down to a stop, I can't take my hands off the bars... she starts a wobble.

 

Try this calculator:

I can pull 6000 rpm in 5th on my T-Sport, but it's not as "comfortable" as a CBR 1000 at that speed. Routinely do just over 100mph when passing; that happens easy and quick...

 

that is one badass lookin' FXDX-T ya got there,man

 

Yeah, nice FXDXT. What's in the motor?? Couldn't open the speed calculator. Maybe mine would pull 6000 rpm in fifth, who knows. With main jet too lean and timing retarded i was pulling 85 TQ/95HP @ 6,000. It's putting out more now. I put in the #175 main jet i forgot and i'm working on writing an ignition map to eliminate low end roll-on pinging. High speed advance should be just right.

 

Burried the needle (120 mph) and still pulling in fifth. (Broke through 100 mph in 3rd). Was still accelerating when I developed a wobble so I backed off. I'll throw the Garmin on one of these days and get a true top speed number.
