My CPR Piped viper with HH hits about 9100 RPM's then falls to about 8800 and stays there. What can I do to fix this? Also what should I be running for rpm's. Also the 8800 shows about 111MPH on the dream meter! What is eveyone elso getting?

Well with information you gave, with no helix numbers, spring color,grams of weight...etc, I would say its obviously overshifting and then cannot recover from the overshift from (A.) secondary helix finish too big (B.) secondary spring not enough spring rate to hold back the overshift (C.) too much weight in the tip of weights . The 9100 right off the bat is from breaking the track loose and therefore overshifting, and then the motor cannot recover. Of course, this is only based off the information provided, to further look into the problem, theres a ton more information required......

If You Running Jeffs Hh Setup, Take Some Weight Out Of Hole 2,mine Couldnt Pull His Setup Either, Had To Go To The 7/16 Head Bolt With 2 Thin Washers And 1/4 Allen In The Hole 1
yeah I am running jeff's setup, however I am not sure what the settings are as I can't remember. I will have to take out the weights tomorrow and check.

If Thats Thing Is Luging Under 9000 Rpm, I Would Let Out, Keep It Above,what Colour Is Your Primary Spring?i Found That Pulling The Allens Out Of The Heal Brought Me Back Up Close Also,but Im Running On Snow No Picks, So Coming Out Of The Hole A Little Lighter Might Be Good,
