I have the 46mm gates and they creep. Make sure if you run them put them on the outside of a turn on the header. My 15 pound springs crept to 18 and that was only to 6500. I bet I will see over 20 if I try to go to peak power.
Thank you for that info will let Big_Al to do that, hes building me the turn downs now, once I get my gates missed them on Friday cause they required a signature.
