Oil Line installation is crucial to engine life. If you are not sure that
you can properly perform this operation, please contact the S&S®
Tech Department for a referral to a shop in your area.
NOTE: Installation instructions are based on an engine and transmission
already in the chassis.

transmission.

manual for instructions—and then remove the oil pan from the
motorcycle.

and use a scribe to mark the location of the 1⁄2" hole as shown in
Picture 8. Use a drill press to machine the 1⁄2" hole as marked in
Picture 8a. Use a small file or deburring tool to make sure no chips
or pieces are left on the 1⁄2" hole and then clean the oil pan and
baffle with solvent before reinstalling the pan with a new gasket
on the motorcycle.
