now that I think about the engine design I s'pose that makes sense... now about the "lack of power" thing...

I've never had issues with the XB's walking :idk: I personally believe because this bike was so TALL and the COG was over a foot higher made it more "paint shaker" than a regular XB

I LOVE a daggone XB and WILL OWN ONE

What about their engine design is so unusual? I thought it was just an ordinary twin.

The angle of the V. That and both sparkplugs fire at the same time. And it's a single throw crank.

Bounces around at idle because of the motor mounts. Once you get moving, everything is smooth..

and it's a crapload of hardware moving all around at once given the size of the engine

If I remember correctly the engine Buell used was a 45 degree twin which supposedly doesn't inherently cancel out vibrations like a 90 degree twin (Duc, TL, SV) does.

Well I had an Aprilia with a 60 degree twin, what about that?

..

What is the advantage of doing it that way? Don't most twins fire in opposing order?

I've never ridden the Uly, I'm not tall enough for that bad boy. I can only speak of the Firebolt, which I own, and the Lightning that I've rode. Oh, and the Blast, which I rode in the MSF and sounds like a go kart.

Aprilia uses a counterbalancer to offset the vibrations. I don't know if Buell did the same thing.
