We love the way our Iron 883 looks and rides, but to tell you the truth the 883cc power plant leaves us with that “need for speed” feeling. Also, since our bike is new and still under factory warranty, we didn’t want to go all crazy and start adding all sorts of aftermarket go-fast parts that would take us to void city.
Both of these aforementioned facts left us in search of some modifications that would speed our bike up, yet let us keep a sound-riding bike. That is where the Screamin’ Eagle 883 to 1200 Stage 1 kit came in. This $1361.95 kit is designed to bring those 883 bikes up to XL1200 specs and includes Sportster Stage I Air Cleaner Kit, XL1200 cylinder heads, and XL1200 cylinders and pistons. With this kit there is no case machining required, meaning the motor can stay in the bike, so the install time is hours and not days.
Once this kit was put on the bike, the real fun began. Bumping up to the 1200cc kit on this 565-pound machine made an already fun bike feel lean and mean with gobs more torque than the old 883cc had. The numbers don’t lie. The stock 883 sees 45 hp and 55 lb-ft and the 1200 kit gets 65 hp with 72 lb-ft. Not only is the performance improvement immense, that’s a pretty healthy horsepower-to-price ratio as well.
If you are into pepping up your Sporty, read along and we’ll show you just how we did it.
1. Here’s a shot of
the stock 883cc
It’s good looking
dressed in all black,
but we wanted some
between our legs.
2. This is what the kit
looked like right out
of the box from H-D.
Now we are going to
get to installing it.
3. To get the access
to the rocker boxes,
heads, and jugs, the
gas tank had to be
4. The throttle body is
connected to those
same parts, so it
had to come off as well.
5. The stock front and rear
pipes were then removed
from the cylinders.
6. The rocker box covers were
carefully removed and given
a bath in degreaser.
7. The rocker boxes were also
removed, inspected, and
8. Both of the heads were untorqued
from the jugs and
9. The pushrods, pushrod
tubes, and tappet blocks
were removed from the
10. Now that all of the ancillary
parts were removed, we
could now take the cylinders
off the bike.
11. We then removed the stock
pistons from the OEM
pushrods. The assembly
12. The New Screamin’ Eagle
pistons were installed onto
the stock pushrods with the
13. New rings from Screamin’
Eagle were also installed
onto the 1200cc pistons.
14. With the aid of a piston ring
compressor tool from H-D,
we slid the new Screamin’
Eagle 1200cc cylinders onto the
15. The stock pushrods, pushrod
tubes, and tappet blocks were
reinstalled using all new gaskets
16. A set of Screamin’ Eagle 1200cc
heads were then added to the
17. We then torqued the heads and
cylinders down to factory specs.
18. The OEM rocker boxes were
reinstalled and tightened within
19. The blacked-out H-D rocker box
covers were then put back on
20. Instead of installing the Screamin’
Eagle “ham can” air cleaner
that came with the kit, we
opted for the SE Heavy Breather
for its looks and performance
21. It was at this time that we upgraded to the
Screamin’ Eagle Performance slip-on Shorty
muffers and black head pipes.
22. We also added black Buckshot heat shields to
add even more black to the setup.
23. The kit came with a heavier clutch spring, so
we frst had to drain the primary case to gain
access to the clutch assembly.
24. Once the fuid was all drained out, we took off
the outer primary case.
25. The old H-D 883 clutch face and spring were
26. The new Screamin’ Eagle 1200 clutch spring
was installed in the stock location.
27. A new primary casket was put on before the
outer primary was reinstalled.
28. New primary case oil was poured into the fller
hole and topped off to specs.
29. And the mission was completed. In a few short
hours we bumped up the old Iron 883’s ponies
by 20 and gained tremendous amounts toque
with the help of our Screamin’ Eagle 1200 kit.
