I just finished swapping out my stock P700's driven spring and relpaced it with the EPI black spring. I also removed both shims. It now squeaks at idle (and slightly surges) in gear but WOW what a difference! My front tires may never touch the ground again! I can now wheelie and feather the throttle to keep the quad balanced.


This mod is well worth the $30 and the time.

is driven spring the primary spring?
