114 hp Sportster drag race 11.40s
Having trouble right now getting the bike back down in the teens. This is
my quickest pass on video. Mph is down from 118 too. starting to shift
without clutch, keeps the wheel down in second gear when i shift like that.
Air was thick the night of racing, waiting on a hot afternoon without
humidity to get some passes, bike makes great power in those conditions.
1992 sporty with factory gearing, 1250 hammer performance kit, xb heads
ported by hammer 1.98 intake valves, 600 lift hammer cams, 45 mikuni with
hammer intake, patriot Exhaust. Bike
makes a 114.8 hp and 88lbs tq on 91 octane pump gas. I weigh 220lbs with
boots, jacket and helmet on.
Buell Exhaust Comparison, Hawk vs. EBR
I switched out the Hawk Exhaust on my
Buell XB12R with an Erik Buell Racing Exhaust. Here's how they stack up.
Both units use all of the stock mounting points, though the Hawk unit keeps
the Exhaust valve servo mount. The EBR
unit has a deeper, smoother sound, which makes it seem quieter. The Hawk
muffler has a sharper tone and will set off car alarms (@2:03). Both pop
regularly off-throttle. On the stock ECM with a K&N the EBR feels much more
torquey and smooth down low. With the right tune I suspect that the Hawk
would make more power on the top end.

Buell XB12R Wrecks Following a Ducati 1198
My buddy riding his Buell XB12R following a Ducati 1198 ends up wrecking
when he doesn't commit to a bend. His riding and lines were on point but I
think coming in hot on the previous bend and almost going wide spooked him
out and he stands the bike up and runs straight into the ditch. Bike and
rider had minor scratches, but rode home fine :-).
