Currently running Heavy Hitters (48.3 base weight) with a 54/46 Dalton helix, Maxx Perf primary spring, red secondary wrapped at 70*. I have the weights loaded up (steel 7/16 bolt, 2 thick washers, one thin) in the tip, (steel 3/8 bolt, one thin washer) in the mid, and 1/2 allen screw in the heel. Can't keep my rpms below the 8500rpm mark. I can throw one more thin washer in the mid, but thats about all I can throw at these weights. Is there a different primary spring I can try to get the rpms to a more favorable peak rpm? Should also mention that I think this is contributing to my poor fuel MPG. I only got about 9mpg the last time I went riding. 
Thanks!
Thanks!

hows the belt or the center to center on your clutch's?
Belt is fairly new and center to center, I'm assuming, is good. Haven't blown a belt since I got the sled and it doesn't squeel. I could try a different belt, but I don't have a brand new one.
