Looking to upgrade my winch cable to synthetic rope on my zforce 800. Anybody done it yet? Looking for some advice on it. What rope to buy ect. Never replaced one. Thanks! 

Buy a good 6mm dyneema rope, or sk 75 fibre. If it melts with a lighter it's fake.
6mm should get you about 20m on the spool.

I replaced my cable with a Dyneema rope.  Your winch cable is held in the drum with a small allen screw.  I unbraided my rope and threaded half through the drum hole and then rebraided it back together.  The full thickness of the rope will not fit through the drum hole.  To access the winch I removed the two bumper blocks and the lower plastic.  It took about 5 minutes to get it off.  That gives you pretty good access to the winch.  Also, make sure that your fairlead rollers are smooth.  If there are any burrs they with catch the rope and tear it.

I've switched my ATV and CFMoto over to rope.  I will never go back to cable.  The rope on my ATV is almost 5 years old.  Its taken a beating but is still going strong.  I've spooled it up wet, drug it over rocks, and generally abused it over and over.  When it breaks, I'll tie a knot in it to get me unstuck.  When I get home, I'll buy another off of Ebay.

It's interesting you mentioned that it doesn't melt.  I tried to melt the end to prevent fraying.  It would not melt.  I guess the Chinese stuff off of Ebay is legit.

One of the first things I did. Found one on Amazon that came with a sleeve and hook already, was fairly cheap and has been great. I wanna say around 60 bucks or something. Never tried burning it though, didn't know that trick. I'll try it some day.

Thank you all for the help! Might just go ahead and change the rollers to the hawse fairlead when I change the cable to rope. Will any hawse Fairlead work or is their a certain size I need?
