you say smoke 'em if you got 'em? Pat Adamek makes Harley horsepower.
Serious horsepower. So when he says TwistGear can tug at big-inch high
output strokers and not back off, you know class is in session. Kinetic
Engines is especially noted for head work, but their expertise reaches
across the decades and encompasses knuckles, pans, shovels, KRs, XLs...if
it's birthmark's a bar and shield, Kinetic can decipher the DNA.

to oversee IronWorks July 2003 TwistGear installation feature, Pat had his
doubts at first. He's been there for a lot of the fads
come and gone over the years, and as the saying goes, fool me once.
But this time he knew there was a bit more to the story than what was
being talked about. What he didn't know was to what degree having a
true close ratio, instead of just a down low first gear, would mean
when it came time to light the fires and kick the tires. Instant horsepower,

(at All Pro Powersports) elicited the somewhat astonished comment — minus
expletives — that the only other bikes to exhibit the same over
the top raw power characteristic (breaking the rear tire loose in 1st-4th)
were turbo bikes making 200-300 horses. This is what having a true
ratio transmission means in terms of performance potential. Because
the torque to roller transfer occurs much quicker, particular
attention to proper tire inflation and tie down is crucial or the
rear end'll hop sideways and walk. Later, in the interests

the right throttle hand just couldn't resist chirping that rear rubber,
