THE 2004 & UP SPORTSTER
From $820.00 |
|
Turn your
new XL
 into
the absolute nastiest hot-rod around! These kits take your Sporty out to
the maximum bore size you can get in your stock cases. Of course, this
engine kit comes with the finest quality components money can buy:
Axtell
all-aluminum, Axtell iron lined aluminum, or Axtell cast iron
cylinders, matching
forged
Hurricane pistons with tool steel wrist pins, Total Seal rings, and
Cometic EST
gaskets! Note: case boring is
required for installation.
90ci Kits With Axtell Cast Iron
Cylinders
Cast iron construction offers
the ultimate in structural integrity and ring seal. This is especially
important in the 90ci application as the cylinder wall becomes thin. Our
testing has shown that aluminum is not strong enough to maintain good
ring seal in this application, but cast iron works very well. Cylinders
come only in black baked finish. Fin highlighting is not available.
Powder coating is available for an additional $100.00

Performance tip: Although
the XB/'04 XL1200 head is a better piece, Thunderstorm type pistons use
an angled squish band that improves chamber efficiency over the flat
bathtub style used in the XB heads. For the optimum in performance, let
NRHS cut a 15 degree squish band into your XB/'04 XL1200 heads and match
this up to a Thunderstorm engine kit. |
