Lubricating a nylon outer cable to help with easing a clutch. Read this might help, but mind what lubricant you use to prevent damage to nylon lining. Before nylon cables I used just gearbox oil. Is this ok with the newer nylon outers ? What lubricant is to be avoided. No funny answers please ! :lol:

Try a silicon based lubricant like gt85

I've always been told,wether its true or just a rumour,that you should never use ordinary oil,such as gearbox oil,on nylon lined cables because it makes them swell up.

I just put a thin layer of silicon grease on - no adverse issues

Most nylons will swell after coming into contact with hydro carbons.

The design idea of nylon lined cables is that they don't need lubrication - but here we are...
Perhaps the wrong grade was used, although that is hard to imagine happening in Lambretta World.

Silicone grease or maybe a decent PTFE lube may work. Are the inners coated too.
You can get PTFE tubing - liners for mig welding torch used on Al. for example - use that to line a regular cable.

^ I use this as well, I only resort to 2 stroke oil if changing a cable when out on the road

Putoline PTFE cable guard spray is the only product I have found that's specifically formulated to help lubricate nylon lined cables.
I also use it on my road (cycle) bikes too. Unfortunately it looks as though Putoline are dropping it from their range of "care products".

That's handy. Got a can of this sitting on the shelf. I thought this was the same as wd40 , but reading the can it contains ptfe. PTFE is also known as Teflon I see after a quick Google of the abbreviation.
