does the swashdrive whip come with the stay up spring under the a bar? i had a knockoff one that did, and i just bought a limited ed rev red one from a guy, but there wasnt a spring under there. there was a hole on the a bar for it, and some kind of notch on the frame, but no spring. i took one off the cheapo and put it on. seems to work fine. just wondering if they come with one out o the box
