Somethings going on with that rpm. With the bender kit they give you loaded up 8ek and new primary spring sec spring and helix.I found that with that kit it would over rev 8900-9000.Run the heel clickers loaded as much as you can in the heel 7-8 washers and 4.5-5.5 tip.I think the bender helix is way to aggresive. I'm running a roller rooster 41\37 silver at 70-80. I also run the shockwave sec at 45 straihgt and it works well to! With the above set up pulls 8600-8700 all the time, pulls hard.
