Cable lubricating has many aspects and much advice.
This site CLICKY has good information on cable lubrication and many other motorcycle tasks.
Personally I use WD40 and copious quantities of engine oil together with a dollop of grease around the lower cable end to delay the effects of gravity on the oil.
I use Inox MX3, the lanox is also very goodboth like like WD40 but way better, won't dry out and evaporate, if you can't get it in the UK there are lots of differnt gun lubes about, I use it on my AirRifle and it stays oily for months
Have fun
