How big do you want it? I had a 98 sportster lx, and a buddy of mine had a 02 sportster lx, the wake keeps getting better and better with more weight, add it evenly or slightly more to the front. 800-1000 and it really starts to shape up nicely! Just watch the rollers, that boat sits low to the water as is and we have had a few actually come over the sides, but hey that just adds more weight until the bilge pumps it out!
