Current motorcycle cable technology uses nylon liners inside the cable and require no lubricant. Oiling them will make the liner turn to mush. The only area that requires lube on this type of cable are the attachment points on the ends and the lever pivots. Check your cables for nylon liners before pouring any kind of lubricant into them.
Just went out to the shop and pulled the crimped end cap off a throttle cable that came off my Bullet this summer. Sure enough, no nylon liner so regular oiling would be in order. I stand by my statement concerning nylon lined cables being ruined by oiling so make sure to check which type you have before oiling. Probably only an issue if you have a cable from a source other than RE. I'm not some young kid from the bicycle shop trying to show off what I know, I am however a 51 year old professional motorcycle technician with many years of experience working on many differant brands.

Thumper.A quick penned line sketch scanned and on here would be appreciated I'm sure (unless of course Kevin sells these in which case I don't want to affect his sales figures)!
