Got the black/violet dalton spring installed and tested it out this weekend. Went from 7400 ish rpms to 7750 ish rpms when i go full throttle from a rolling start, until it starts revving out to 8050. I didnt notice any over revving or lost speed on the top end so thats a plus. For $40 CAD im happy with the results, pulls noticeably harder now. The last ride of the weekend i got a rock caught in between the brake and the rim punching a hole through the wheel, so now ive got some 28" blackwater evo's with STI HD3's on order, 6+1 offset. Hopefully i don't loose rpms again lol
