Did my 1st oil change on my soft tail this week end . Everything went good . Put mobile 1 v-twin mobile in the engine , spectro in transmission and the hd oil in primary . I wimped out a little on the torque on the plugs , i torqued them to 15 ft. Lbs. , didn't want to strip the threads . I did notice that from the 1000 mile service the dealer used teflon sealant on the threads so i also used that when putting back in . I also changed both o-rings no way could i reuse the old ones so not sure if the dealer changed them or not . I don't have a jack to lift it up so i did have a transmission spill do to the fact my oil container was just high enough so i could't get my hand between it and the plug so had to drop the plug and quickly move the container under it . When i loosened both plugs they really didn't seen that they were that tight but they never leaked either , that's why i just torqued to 15 ft. Lbs. , it was very gratifying doing the work myself .
