installed it today. haven't went for a ride yet, i still need to find a screw to put that last spring in. but the weight difference on the hub is INSANE. the clutch is MUCH quieter now
Took it for a spin, bike revs up and down much quicker and feels alot more free. 6 springs feels MUCH better than 4.
however after removing my Rapid bike 3 module, the bike started surging like nuts 2-3k hunting, shut it off, unpluged o2 sensor, then it was fine, pluged o2 back in, and it was fine again. sporatic surging.
