If you are running a VM36 with the stock throttle...you either have to buy a cable from Lancer, have someone custom make you one, or make one yourself.
I bought the parts I needed from a bicycle shop, and I used the stainless teflon coated inner wire. It is really smooth....took me a while to learn how to solder to stainless. I needed a special flux.
If you are at all handy with a soldering iron, you can get throttle cable kits from Venhill. The inner cable is galvanized to make it easy to solder - but it didn't make a cable as smooth as the stainless inner and bicycle shop outer.
