Just picked-up a service manual for 02 Sportster. Glad I did, it contains a bunch of good info and will save me $285.00 that HD wants to charge for the 1000 mile service! Just a quick question though: on reading about the primary oil change/drain, the book does not state to put any type of Loctite on the threads. Should I Loctite it before reinstallation? Thanks for any info.
