I read on RM ATV that it was a requirement but have never read that type of info here or at RF before? Thanks.

they are not required even for the stage 3 cam....u can check out their site and it says there......some may advise to upgrade springs if u spend a lot of your time up around 7500 rpm......my personal experience has been very good with the HC2 and would recommend it for quick, cheap, and very easy HP :rockit:

DL700 is dead on the money. It seems that they always confuse the 660 for the 700.......I know about a 100 people running the Hotcam stage 2 on stocks springs, and beatin' the snot out of 'em with no problems:thumb:
