If somebody could answer this without me having to measure them that would be awesome. My belts have seen better days, I have the greddy pulleys (no air pump). The other is still stock. I need either a part number or the length of these things. Thanks a bunch to the person who answers this.

 

i believe it is 5pk780. it has been a while, i could be wrong...
try the search function.

 

That sounds about right, good luck trying to find the right belt, i dont think they make it. I tried to find one for my friend and no one seems to make one. I know they make a 4pk780 or something similar, i'm using the 4 pk740 but i'm not using the pulley kit. www.k2rd.com sells the belt for $15.

 

The replacement is the 5PK775. Check here: http://www.k2rd.com/Online_Catalog/FD3S/FD3S-index.htm
