STEP 20: 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 then the engine you will need to follow the instructions listed below.
Install the recommended amount of oil and type per your riders owners manual in oil tank.
1. Following the start up instructions in box 3. Ride the motorcycle until the engine is up to oper-
ating temperature.
2. Idle motorcycle on kickstand for 2 minutes. Turn the motorcycle off and with the motorcycle
still on kickstand, remove and check oil level on the dipstick. Add oil if necessary until oil reg-
isters on the upper groove of dipstick (Full, Hot Line.)
Oil Cooler Recommendation: (ALL MODELS)
The JIMS 120, 131, or 135 should be fitted with an effective oil cooler. JIM'S recommends you
use the current H-D Accessories Book Oil Coolers. Order your cooler kit for the correct year and
model of the motorcycle.
Chassis Oiling System:
Make sure that the entire oiling system is clean. If you are fitting your new JIMS 120, 131, or 135
Race Kit engine into a chassis that has been used, be sure to completely clean the oil tank together
with all lines and fittings leading to and away from the engine. If the old engine has more than
20,000 miles of use, or, if it has suffered any unusual wear, dismantle the oil pan and hoses and
thoroughly clean them.
