Hi, this is my 1st post so I hope im doing it right. I pulled my bike apart a few months ago and am just putting it all back together. What I need some help with is my hyper charger. I found a small spring on the ground and think it is for the end cap that holds the butterfly shaft together. Does this sound right and if so should there be another spring for the bottom end cap? if someone knows I would appreciate some help. Thanks
