well i got my new clutch cable, motion-pro. im also installing the HD easy clutch ramps. i contacted motion-pro about lubing the cable but they said it wasn't necessary, if i were to try and lube it, with what and how.
Hang the cable up by one end, open up the adjuster all the way until it comes apart, apply a light/cable lube to the top end and the adjuster, work the cable back and forth. Repeat a few times leaveing it hang. hope this helps.
im going to see if checker or autozone carry a liquid graphite. i assume you were in the 82nd. i was there for awhile before i shipped to the 173rd. that was way back when.
