the engine when you start up.
Front cylinder head mount 2008 to present Touring models
JIMS engines come with the mounting hole provisions for the front head mount
to be installed without any modifications. You can use your original mount and
hardware or chrome, polished or black anodized JIMS Billet front head mount
and chrome Heim joint link. This is a stronger and better looking mount sys-
tem. Order separately. See JIMS No.1437 and 1444 in catalog or on the web-
site. Follow either H-D service manual or JIMS instruction sheet for installing the
front head mount and torque specifications.
All Models Installing Primaries and Clutch:
Follow installation instructions for inner and outer primary, clutch assembly,
sprockets, primary chain, adjustment and alignment, per H-D service manual
for the year and model you will be working with.
Engine Compensator recommendation:
We recommend a H-D No.40274-08A or equivalent. This kit comes with heav-
ier springs and increased travel to meet the demands of race engines. This kit
will support up to 7 times the energy absorption capacity of the original equip-
ment compensator In return, this will help protect the engine and driveline
components during extreme drag race launches. The 2012 & 2013 models
come stock with this.
Clutch Recommendation:
The high torque output of the JIMS Race engines do require a clutch with in-
creased torque capacity. The Screamin’ Eagle
® No. 37976-08A clutch or JIMS
High Performance Billet Clutch No. 8382 are two examples you can use.
Battery :
It is very important to always use a well maintained battery with performance
engines. Always keep a full charge on the battery or you will cause damage to
the starter drive system. JIMS recommends usage of the H-D OEM maintenance
free battery for the correct model application.
Battery Cables:
JIMS recommends Super Flex performance battery cables because of the ma-
terial quality of the cable and eyelets and flexibility. See JIMS catalog for a full
model selection.
Starters and RIng and Pinion gear sets:
If your starter can't handle that big inch engine or is just plain worn out see JIMS
New 2013 catalog for our selection of Performance High Torque starters. We
also offer High Torque Starter Ring and Pinion Gear Sets to help take the stress
of your starter.
Ignition for Carbureted:
Follow the ignition manufacturers instructions when installing per application.
JIMS recommends for carbureted models the JIMS Race Ignition that can be or-
dered separately from JIMS’ Sales Department.
Use JIMS No. 2344 JIMS Race Ignition on 1999 - 2003 Alpha carbureted mod-
els.
Use on 2000 - 2003 Beta carbureted models.
Use H-D 32124-04 ignition race turner or equivalent on 2004 - 2006 Alpha or
Beta carbureted models.
Tuning for EFI:
Application information for fuel injected engines
JIMS recommended ignition for fuel injection engines is the Screamin' Eagle
Pro Super Tuner and the Screamin' Eagle Pro Tuner Software with "Smart Tune".
You may also need a Pro Tuner cable kit and a Pro Tuner training DVD. These
are for race application only.
Use H-D 32109-08C Screamin' Eagle Pro Super Tuner for 02 and later EFI Dyna,
Softail, and 02 - later EFI Touring, and Trikes.
