    i adjust my clutch (on both xj700's) with just a little play and after putting a couple hundred miles or so the play will get bigger like the locknuts are coming loose but theyre not and both top and bottom adjusters are tight so is my cable stretching? I have new clutch cables too

    You did lube the new cable when you installed it, right?

    Because new cables need to be lubricated too. They come "dry" and the inner sheath will quickly wear if the cable is not properly lubed.

    depends on what the inner sheath is made of. never oil teflon, nylon maybe, generic or doesn't say, go ahead and oil it

    Teflon sheathed cables should be lubed. It will extend their life, and flush out any grit that finds it's way inside the sheathing, as well as preventing the cable from corroding.

    Teflon non-reactive with everything except molten alkali metals and highly reactive fluorinating agents (cable lubes are not flourinating agents).

    Well golly, I use Tri-Flow which contains of all things... PTFE (DuPont's brand name for PTFE is Teflon.) I'm thinking Teflon lube should be fine with Teflon cables.

    Lube your cables. Even if new.

    Get one of these and make it easy on yourself:

    More on PTFE from Wikipedia:

    "The best known brand name of PTFE-based formulas is Teflon by DuPont Co., who discovered the compound."

    "neither water nor water-containing substances wet PTFE..."

    "PTFE has one of the lowest coefficients of friction against any solid."

    TriFlow: http://www.triflowlubricants.com/Tri-Fl ... icant.html

    I also have a tube of TriFlow grease. Good stuff.

    why should you "oil" it then?

    Stuff dosen't stick to Teflon, but grit will abrade it, and steel cables will rust.

    right you are, i guess it pays to get pre-lubed cables with stainless wire

    Maybe it does, but I like the smell of oil of wintergreen, so I'd lube the cable anyway just for that.

    I got a cable luber tool (pictured above) and am about to replace my clutch cable (thanks Len!).

    Is the cable luber supposed to spit/ leak when applying lube to the new cable?

    Cable sheath/ crimp is 'topped' out in the luber tool and the bare cable is coming out of the small slit on top of tool.

    Thanks!

    Yes, the cable luber will spit/leak when being used, I always just wrap a shop rag around it; plus another one at the other end of the cable to catch the lube once it starts spewing out there.

    Thanks Fitz.
    Good, got it.
    Doing choke cable now.
    Edit - struggled with sheath/crimp staying in place on choke control lever ..... Set cable position proper on carb connection and all is good! :D

    Sadly enough I cracked the nipple off my fuel filter taking the tank off. Gonna put a straight fuel line on an go for a ride! :D :D

    That just means it's time for a new one.

    I got my cable luber from the Yamaha dealer I bought my '78 SR500 from, back in '79, as a promo gift with the new bike.

    It's blue and gold and has "YAMAHA" stamped into it. I had never seen one before. Nowadays, I use it all the time.
