Owners Manual For All JIMS ® Engines 120, 131, & 135
Thank you for purchasing one of JIMS engines, which has been designed and
manufactured to give years of safe Racing fun.
This owners manual gives you an in-depth look at the maintenance required
to keep your JIMS engine running strong. Any and all repair information that
is needed can be found in a service manual for the year and model of JIMS
engine you have installed in your motorcycle.
The use of an H-D parts book will be helpful for viewing the parts and part
numbers required for any repair. Please note that all JIMS engines use a Timken
bearing for the retention of the flywheel assembly in the left case. With that
being said, you will also need a service/parts book and manual for model year
2002.
JIMS will be making periodic improvements to these engines. With these im-
would not fill and pits would be empty. There would be no friendly arguments
about 'which cam' or 'what exhaust' works best. Drag racing is one of the most
popular motor sports in America. The fans are often racers themselves, have
been racers, want to be racers or know a lot about the nuts and bolts of drag
racing. We at JIMS have spent years developing the JIMS 120, 131, & 135 Race
engine for drag racers and those who want to become drag racers. The 120,
131, & 135 engine is a strong, ground pounding and reliable base for your ex-
ploration into the complex and fascinating sport of drag racing. We hope you
enjoy your new 120, 131, & 135 as much as we are pleased to bring it to you.
Pre Start procedures:
Do not connect the oil return line from the engine to the oil tank. Fit a hose
from the engine’s oil return fitting and run the hose into a large catch-pan.
Note: Remove the spark plugs from the engine. Attach the plug wires to the spark
plugs and lay them on the cylinder heads to prevent damage to the coils.
Be sure the oil tank is properly filled with the correct oil. Use the electric starter
to turn the engine until the oil pressure light goes out or until the pressure
gauge reads 10 -15 psi. Re-install the spark plugs, torque to 12 to 18 ft lbs., at-
tach plug wires. Depress both compression release plungers. You can hold the
rear compression release plunger as the engine is trying to start. After engine
has started, release compression release plunger. Allow the return oil to run
into the catch pan. Run engine between 900 and 1500 rpm until the tops of
the cylinders have reached 200 degrees Fahrenheit (too hot to touch). This
normally takes between one and two minutes. Note: Do not allow the oil level
in the tank to get too low while the engine is running. Stop the engine and let
it cool to room temperature. Inspect the installation for any oil or gasoline leaks.
Top – off the oil tank. Repeat the warm-up and cool-down procedure three ad-
ditional times. Note: Watch and maintain the oil level in the tank. You may re-
connect the oil return line to the oil tank after at least two quarts of oil have
been pumped into the catch pan. Discard the oil in the pan.
EVO-TWIN CAM: Checking and Adding Oil
Caution: If JIMS EVO Twin Cam engine will be installed in a Softail or
any model motorcycle that will have its oil tank higher than the engine,
you will need to follow the instructions listed below. Install the recom-
mended amount of oil and type per your owners manual in oil tank.
Ride the motorcycle until the engine is up to operating temperature. Idle mo-
torcycle on kickstand for 2 minutes. Turn the motorcycle off and with the bike
still on kickstand, remove and check oil level on the dipstick. Add oil if neces-
sary until oil registers on the upper groove of dipstick (Full, Hot Line.)
Performance Twin Cam Engines:
Valve Train Components should be inspected every 5000 miles of service. More
often if an engine is used under severe racing conditions, i.e. full throttle race
operation. As with all high performance engines, components are under or
subject to more stress in one-way or another, many times more than a stock en-
