For a bike that did not come with a slave sylinder this is a band aid, best save your money and re-route the cable and lube. Put your bike on a stand and rotate the bar's, you can see and feel where it binds. It's not a cable routing issue. While I agree it's not like a KTM with a built-in slave cylinder (I have one) it is still MUCH improved over stock. The pull is much lighter, the engagement better and it doesn't fade or need adjusting while riding. Well worth it IMO. There is always the rekluse option though.
